Chapter 6

Necrophore

The Lazaret classes the pupating brood as Necrophore; common folk call it wakelight, for the light its adults carry. It is the only brood that wants nothing from the living, and the one a party leaves behind, in its dead. The Lazaret’s standing instruction for it: make no light, make no dead.

How a necrophore works

The brood is three lines of moths on one closed loop: adults lay in fresh corpses, larvae climb out and eat the dead, and a larva killed by the wrong damage seals into a husk and opens as an adult. Nothing is implanted in the living, nothing infects, and nobody catches anything. What the brood needs is bodies, and a party moving through its territory produces them faster than anything else in the world.

NOTE

Nothing a line leaves behind hampers that line. Gravewax is Difficult Terrain for everything except the tallow line that laid it down, and a lychfield — every line’s leavings at once — is Difficult Terrain for everything except Necrophores.

Reproduction

A corpse becomes seeded when an adult lays in it, and a seeded corpse takes no further laying. An adult never gets inside a body — a moth the size of a fishing boat could not — so it settles over the corpse and lays through its ovipositor. An eligible corpse has been dead no longer than 24 hours and contains no living sallow graft. A corpse with a living sallow graft cannot be seeded. Once its Quagdam emerges, the remains are no longer eligible.

The chronology after a death is:

An adult that reaches an eligible, unseeded corpse lays immediately. An adult present at the death can reach it with its Seed the Dead Reaction.
Inside established colony ground, an eligible corpse that remains unseeded becomes seeded exactly 3 hours after death. This 3-hour rule applies only to established ground and replaces the adult-arrival roll there. It represents an adult laying while unobserved.
Outside established ground, 1d4 adults arrive 1d6 + 2 hours after a death that draws them: a minimum of 3 hours and a maximum of 8. If the corpse remains eligible and unseeded, the first adult to reach it lays; the others remain nearby and fight interference.
The larvae emerge 1d6 + 2 hours after laying: a minimum of 3 hours and a maximum of 8.

A corpse seeded by the fixed 3-hour rule therefore hatches 6–11 hours after death; a corpse first reached by arriving adults hatches 6–16 hours after death. An adult present at the death produces larvae 3–8 hours after death.

Adult	Lays in	Larvae
Emberwing	An eligible corpse	1d4 Cinder Nits
Tallow Imago	An eligible corpse	1d4 Gravewax Grubs
Reliquary Imago	An eligible corpse	1d4 Crypt Instars

The cinder nit and gravewax grub can pupate after hatching. A Crypt Instar must first feed on the dead for 30 days and grow into a Sepulchre Nymph. Pupation begins when one of these three final larval forms drops to 0 Hit Points from anything but its line’s destructive damage.

NOTE

Adults lay outside a fight as well. Seed the Dead resolves a laying the party can see. The established-ground rule resolves adult visits that happen out of sight.

Pupation and the husk

Three creatures in this chapter pupate: the cinder nit, the gravewax grub, and the sepulchre nymph. Each is the last larval stage of its line, and each carries the Pupation trait on its stat block. The trait always works the same way: reduced to 0 Hit Points by anything except the damage its line cannot survive, the larva seals where it stands as a husk, and 1 hour later the husk splits and the adult takes its first turn.

Each husk has a stat block of its own, at the end of this chapter:

Line	Husk	Destroyed by	Opens as
Ember	Cinder Nit Husk	Cold	Emberwing
Tallow	Gravewax Grub Husk	Cold or Thunder	Tallow Imago
Reliquary	Sepulchre Nymph Husk	Radiant	Reliquary Imago

Nothing else husks: instars and masses are destroyed at 0 Hit Points like anything living, and an adult, once opened, never seals again. During its hour a husk is immune to every condition, takes no actions, and keeps its Vulnerability to its line’s damage the whole time.

NOTE

Failed husks. Not every husk opens. In a rare few the change halts partway, and the light that should have flown stays where it is and roots. What that becomes is the Lych Lantern.

A colony’s territory

A Necrophore colony has no den and no center. Its territory is wherever corpses are. A site becomes established ground when a Necrophore adult opens from a husk there. Established ground uses the fixed seeding step under Reproduction and has no adult-arrival roll.

Adults navigate by warmth and by one another’s light. Fresh death outside established ground can draw them from nearby territory, and a Wakelight Wisp can reveal a corpse to every adult within 1 mile.

A corpse burned, frozen, sunk in running water, or sealed from the air before seeding produces nothing. Burning or freezing a seeded corpse before its larvae emerge also ends the laying. The Lazaret pays for clearing every corpse from a battlefield before these windows close.

Reading the ground

The signs are leavings: split husks beside old bones, runnels of gray wax down a stair, scorch-rings in grass nothing ever burned, small carcasses wedged into thorn trees at head height — the last being not the brood but the thing that hunts it. A creature that succeeds on a DC 13 Intelligence (Nature) or Wisdom (Survival) check reads the signs, and the age of the oldest husk dates the colony.

Resting and light in a colony’s ground

Fire after dark in a colony’s ground is a beacon, and so is a lantern. A party that keeps a cold, dark camp passes the night beneath the colony’s notice unless something nearby dies.

The diseases

The Necrophore has no disease and no counter: nothing in this chapter infects a living creature, and nothing here is cured. Of the spells in What magic does, two have a use against this brood:

Detect Poison and Disease marks every seeded corpse in range.
Gentle Repose prevents a corpse from being seeded. An already seeded corpse’s clock stops for the spell’s duration, and a body can be carried home through the brood’s own territory.

The creatures

The ember line

The ember line runs hot: its larvae hatch warm, its adults carry a banked-coal heat instead of a lamp, and its territory smells of ash where nothing ever burned. Cold is what it cannot survive:

Cinder Nit

Tiny Monstrosity, Unaligned

The first stage of the ember line: a hot, restless mite the color of a banked coal, hatched from eggs laid in a fresh corpse. It feeds on carrion and warmth. Killed by anything but cold, it seals where it stands and finishes becoming an emberwing.

Cinder Swarm

Medium Swarm Of Tiny Monstrosities, Unaligned

Where one corpse held many eggs, the nits stay together: a rustling, glowing carpet that moves like poured coals and strips a body to the bone in a night. A swarm is not a pack. It is a nursery that has learned to walk.

Emberwing

Small Monstrosity, Unaligned

The winged adult of the ember line: a moth of ash and smoldering wing that hunts by its own dim glow and lays its eggs in the newly dead. Everything it lands on, it scorches.

Pyre Matron

Large Monstrosity, Unaligned

An emberwing that has outlived enough layings: heavy as a warhorse, wings like sheets of beaten char, the air above her shimmering with body heat. Matrons roost where the dying has been steady for years — border forts, plague towns, roads the wars keep using — and the ground beneath a roost never frosts.

The tallow line

The tallow line renders the dead: its larvae turn a corpse’s fats into gravewax, its adults carry the corpse-light, and everything it holds long enough ends up sheeted in gray. Cold cracks it and thunder shakes it apart:

Gravewax Grub

Small Monstrosity, Unaligned

The larva of the tallow line: a fat, slick, candle-pale worm that feeds on the fats of the dead and renders them into gravewax. Killed by anything but cold or thunder, it hardens into a husk and opens as a tallow imago.

Wax Spit (1/Day). Dexterity Saving Throw: DC 12, each creature in a 15-foot Cone. Failure: 7 (2d6) Bludgeoning damage, and the target’s Speed is 0 until the end of its next turn. Success: Half damage only.

Gravewax Mass

Large Monstrosity, Unaligned

In a rich larder — a plague pit, a sealed barrow, a battlefield plowed under — the grubs of several corpses meet, and rather than compete they fuse under a shared coat of their own wax. The mass moves like slow porridge and eats like a tide.

Pseudopod. Melee Attack Roll: +5, reach 10 ft. Hit: 12 (2d8 + 3) Bludgeoning damage plus 3 (1d6) Necrotic damage.

Wax Slough (Recharge 5–6). Dexterity Saving Throw: DC 13, each creature in a 10-foot Emanation originating from the mass. Failure: 10 (3d6) Bludgeoning damage, and the target’s Speed is 0 until the end of its next turn as the wax sets on it. Success: Half damage only.

Tallow Font

Large Monstrosity, Unaligned

A mass that stopped moving. Anchored over a deep larder, it turns entirely to rendering: a pale, breathing hummock that sheets its chamber in gravewax and feeds the line's young the way a spring feeds a valley. The Lazaret classes fonts as infrastructure rather than fauna, and burns them with the same priority as bridges.

Traits

Rooted. The font can’t move and can’t be moved against its will.

Waxen Ground. The ground within 15 feet of the font is sheeted in gravewax and is Difficult Terrain for creatures other than Necrophores of the tallow line. A creature that takes the Dash action while on it must succeed on a DC 12 Dexterity saving throw or have the Prone condition.

Font. A Necrophore larva that starts its turn within 30 feet of the font regains 5 Hit Points.

Rendered Deep. When the font drops to 0 Hit Points, unless the damage that reduced it was Cold or Thunder damage, it collapses in a wave: each creature within 15 feet of it makes a DC 12 Dexterity saving throw, taking 14 (4d6) Bludgeoning damage on a failed save or half as much damage on a successful one, and 1d4 Gravewax Grubs emerge from the ruin with their full Hit Points.

Actions

Multiattack. The font makes two Scald attacks.

Scald. Ranged Attack Roll: +5, range 30 ft. Hit: 7 (2d6) Bludgeoning damage plus 4 (1d8) Fire damage, and the target’s Speed decreases by 10 feet until the end of its next turn as the wax sets.

Tallow Imago

Large Monstrosity, Unaligned

The flying adult of the tallow line: a heavy, greasy moth shedding a sick corpse-light. The wax held only the grub; the wings open as it rises, which is how it ends up spanning a cart. It drains the living with its bite, lays in whatever dies near it, and keeps the last hour of every creature its larva ate, pantomiming them without a voice.

Traits

Corpse-Light. The imago sheds Bright Light in a 30-foot radius and Dim Light for an additional 30 feet. A creature that starts its turn in that Bright Light and can see the imago makes a DC 13 Wisdom saving throw. On a failed save, the creature has the Charmed condition until the start of its next turn, and it must move toward the imago on its turn if able.

Inherited Memory. The imago retains the final hour of memory of every creature its larval stage consumed. It can pantomime those memories but can’t speak them.

Actions

Multiattack. The imago makes two Proboscis attacks.

Proboscis. Melee Attack Roll: +6, reach 10 ft. Hit: 10 (2d6 + 3) Piercing damage plus 7 (2d6) Necrotic damage, and the target’s Hit Point maximum decreases by an amount equal to the Necrotic damage taken. The reduction lasts until the target finishes a Long Rest.

Scale Cloud (Recharge 5–6). Constitution Saving Throw: DC 13, each creature in a 20-foot Emanation originating from the imago. Failure: 18 (4d8) Poison damage, and the target has the Blinded condition until the end of its next turn. Success: Half damage only.

Bonus Actions

Guttering. The imago extinguishes or reignites its Corpse-Light, or it moves up to half its Fly Speed without provoking Opportunity Attacks.

Reactions

Seed the Dead. Trigger: A creature the imago can see dies within 30 feet of it. Response: The imago moves up to half its Fly Speed toward the corpse without provoking Opportunity Attacks. If it ends that movement within 5 feet of the corpse, it settles over the body and lays through its ovipositor. After 1d6 + 2 hours, 1d4 Gravewax Grubs climb out of the body.

Catafalque Moth

Huge Monstrosity, Unaligned

The tallow line's elder: a moth the size of a fishing boat that no longer bothers to fly far, draping itself over biers, gatehouses, and charnel-chapel roofs like a pall laid by an enormous hand. Its corpse-light is the softest in the brood and the hardest to look away from. What it remembers, it remembers in crowds.

Corpse-Light. The moth sheds Bright Light in a 30-foot radius and Dim Light for an additional 30 feet. A creature that starts its turn in that Bright Light and can see the moth makes a DC 15 Wisdom saving throw. On a failed save, the creature has the Charmed condition until the start of its next turn, and it must move toward the moth on its turn if able.

Inherited Memory. The moth retains the final hour of memory of every creature its larval stage consumed. It can pantomime those memories but can’t speak them.

Actions

Multiattack. The moth makes two Proboscis attacks.

Proboscis. Melee Attack Roll: +9, reach 10 ft. Hit: 16 (2d10 + 5) Piercing damage plus 9 (2d8) Necrotic damage, and the target’s Hit Point maximum decreases by an amount equal to the Necrotic damage taken. The reduction lasts until the target finishes a Long Rest.

Wing Pall (Recharge 5–6). Constitution Saving Throw: DC 16, each creature in a 30-foot Emanation originating from the moth. Failure: 27 (6d8) Necrotic damage, and the target’s Speed is halved until the end of its next turn as settling wax coats it. Success: Half damage only. Failure or Success: Nonmagical flames in the Emanation are extinguished.

Bonus Actions

Guttering. The moth extinguishes or reignites its Corpse-Light, or it moves up to half its Fly Speed without provoking Opportunity Attacks.

Reactions

Seed the Dead. Trigger: A creature the moth can see dies within 30 feet of it. Response: The moth moves up to half its Fly Speed toward the corpse without provoking Opportunity Attacks. If it ends that movement within 5 feet of the corpse, it settles over the body and lays through its ovipositor. After 1d6 + 2 hours, 1d4 Gravewax Grubs climb out of the body.

Legendary Actions (3/round)

Immediately after another creature’s turn, this creature can expend a use to take one of the following actions. It regains all expended uses at the start of each of its turns.

Drift. The moth moves up to half its Fly Speed without provoking Opportunity Attacks. The moth can’t take this action again until the start of its next turn.

Wax Fall. Dexterity Saving Throw: DC 16, each creature in a 10-foot Emanation originating from the moth. Failure: 9 (2d8) Bludgeoning damage, and the target’s Speed decreases by 10 feet until the end of its next turn. Success: Half damage only. The moth can’t take this action again until the start of its next turn.

Seize. The moth makes one Proboscis attack. The attack deals only its Piercing damage, with no Necrotic damage. The moth can’t take this action again until the start of its next turn.

The reliquary line

The reliquary line remembers: its young feed slowest and grow largest, its adult speaks in the voices of everything it has eaten, and its territory is wherever the dead were laid with care. Radiance is the one thing it cannot pass through:

Crypt Instar

Small Monstrosity, Unaligned

What climbs from a corpse the reliquary line has seeded: a hand-length burrower, translucent as church glass, that spends thirty days eating before it is anything worth a file. Instars work in broods, dragging the newly buried down through the floors of their graves.

Sepulchre Nymph

Medium Monstrosity, Unaligned

The ground stage of the reliquary line, grown from an instar that fed well: a burrower strong on the dead it drags under. Killed by anything but radiance, it seals into the hardest husk the brood makes and opens as a reliquary imago.

Bonus Actions

Burrow Away. The nymph burrows up to half its Speed without provoking Opportunity Attacks.

Reliquary Imago

Huge Monstrosity, Unaligned

The apex of the reliquary line: a vast, luminous moth that carries the final memories of everything its larva ate and speaks in their voices. The husk held only the body; the wings come out folded and open as it rises, which is how it ends up shading a road. A creature that has eaten the right corpse knows things nobody living knows.

Reliquary Light. The imago sheds Bright Light in a 30-foot radius and Dim Light for an additional 30 feet. A creature that starts its turn in that Bright Light and can see the imago makes a DC 17 Wisdom saving throw. On a failed save, the creature has the Charmed condition until the start of its next turn, and it must move toward the imago on its turn if able.

Inherited Memory. The imago retains the final hour of memory of every creature its larval stage consumed, and it can speak in any of their voices.

Actions

Multiattack. The imago makes three Proboscis attacks. It can replace one attack with a use of Charnel Shroud.

Proboscis. Melee Attack Roll: +11, reach 15 ft. Hit: 17 (2d10 + 6) Piercing damage plus 13 (3d8) Necrotic damage, and the target’s Hit Point maximum decreases by an amount equal to the Necrotic damage taken. The reduction lasts until the target finishes a Long Rest.

Charnel Shroud. Constitution Saving Throw: DC 18, each creature in a 20-foot Emanation originating from the imago. Failure: 27 (6d8) Necrotic damage, and the target has the Blinded condition until the end of its next turn. Success: Half damage only.

Bonus Actions

Guttering. The imago extinguishes or reignites its Reliquary Light.

Reactions

Legendary Actions (3/round)

Immediately after another creature’s turn, this creature can expend a use to take one of the following actions. It regains all expended uses at the start of each of its turns.

Drift. The imago moves up to half its Fly Speed without provoking Opportunity Attacks. The imago can’t take this action again until the start of its next turn.

Wing Dust. Dexterity Saving Throw: DC 18, each creature in a 10-foot Emanation originating from the imago. Failure: 10 (3d6) Poison damage. Success: Half damage only. The imago can’t take this action again until the start of its next turn.

Seize. The imago makes one Proboscis attack. The attack deals only its Piercing damage, with no Necrotic damage. The imago can’t take this action again until the start of its next turn.

The husks

A husk is an hour of work left undone. It does nothing, it cannot be moved, and only its line’s damage reaches what is sealed inside:

Cinder Nit Husk

Tiny Monstrosity, Unaligned

A nit that died of anything but cold, sealed where it stood: a knot of hardened ash the size of a walnut, warm to the touch and faintly lit from inside. It has an hour’s work to do and no way at all to defend itself while it does it.

Traits

Sealed. The husk can’t take actions, and its Speed can’t be increased. Nothing reaches what is inside it except Cold damage.

Opening. One hour after the husk forms, it splits and an Emberwing emerges in its space with its full Hit Points and takes a turn immediately. Destroying the husk before then ends the line’s cycle here.

Gravewax Grub Husk

Small Monstrosity, Unaligned

A grub sealed inside its own rendered wax, pale and smooth and warm as a living body. The surface sets hard enough to turn a blade and stays soft enough to hold a thumbprint, which is how a Lazaret officer tells this hour from the next.

Sepulchre Nymph Husk

Medium Monstrosity, Unaligned

The hardest thing this brood makes: a case of packed grave-earth and fused casings, the size of a curled person, that rings like fired clay when it is struck. Light is the only thing it was never able to keep out.

Strays of the wake

Two creatures belong to no line and to all three. The Lazaret files them under malformations, which is accurate for one of them:

Wakelight Wisp

Tiny Monstrosity, Unaligned

A scrap of living wing that peels from an adult in flight and drifts on its own, dim and warm and searching. Wisps are how a colony finds the dead it did not make: they ride the wind until they cross a corpse, then settle and brighten.

Immunities: Poison; Charmed, Exhaustion, Frightened, Grappled, Poisoned, Prone

CR: 1/4 (XP 50; PB +2)

Traits

Wakelight. The wisp sheds Dim Light in a 20-foot radius.

Death Sense. The wisp knows the location of any dead creature within 300 feet of it.

Actions

Scorch. Melee Attack Roll: +4, reach 5 ft. Hit: 4 (1d4 + 2) Fire damage.

Beacon. The wisp settles on a dead creature within 5 feet of it and brightens, shedding Bright Light in a 30-foot radius and Dim Light for an additional 30 feet until it moves or is destroyed. Every Necrophore adult within 1 mile knows the location of a corpse a wisp has beaconed.

Bonus Actions

Snuff. The wisp extinguishes its light or rekindles it.

Lych Lantern

Small Monstrosity, Unaligned

Not every husk opens. In a rare few the change halts partway: the thing inside dies, the light it was growing does not, and the sealed case roots where it stands. What remains is a lantern of shell and wax, glowing softly, forever — and the glow calls to whatever is close to death.

Resistances: Necrotic
Immunities: Poison; Blinded, Charmed, Deafened, Frightened, Poisoned, Prone
Senses: Blindsight 60 ft., Passive Perception 11
CR: 2 (XP 450; PB +2)

Traits

Rooted. The lantern can’t move. Uprooting it requires a successful DC 15 Strength (Athletics) check; an uprooted lantern dims and dies within 1 hour.

Grave Glow. The lantern sheds Bright Light in a 20-foot radius and Dim Light for an additional 20 feet. A creature that has fewer than half its Hit Points remaining, starts its turn in that Bright Light, and can see the lantern makes a DC 12 Wisdom saving throw. On a failed save, the creature has the Charmed condition until the start of its next turn; while Charmed this way, it must move toward the lantern by the most direct route on its turn, and if it ends its turn within 5 feet of the lantern, it has the Incapacitated condition until the start of its next turn.

Actions

Root Lash. Melee Attack Roll: +4, reach 10 ft. Hit: 6 (1d8 + 2) Bludgeoning damage plus 3 (1d6) Necrotic damage.

Reactions

Flare. Trigger: The lantern takes damage. Response: Constitution Saving Throw: DC 13, each creature within 10 feet of the lantern that can see it. Failure: The creature has the Blinded condition until the end of its next turn.

Their hunter

The brood has a predator, and the Lazaret’s files on it are unusually warm:

Mort Shrike

Large Monstrosity, Unaligned

A gaunt, hook-beaked bird the size of a pony that feeds almost entirely on the wakelight brood: it hawks adults out of the air, cracks husks like nuts, and wedges its surplus into thorn trees at head height. Where the brood is thick, shrikes follow, and their larders mark a colony's borders more reliably than any survey.

Skills: Perception +5

CR: 5 (XP 1,800; PB +3)

Traits

Husk-Cracker. The shrike deals double damage to objects and to Necrophore husks.

Wake Sense. The shrike knows the location of any Necrophore creature within 300 feet of it.

Actions

Multiattack. The shrike makes one Beak attack and one Talons attack.

Beak. Melee Attack Roll: +7, reach 5 ft. Hit: 13 (2d8 + 4) Piercing damage.

Talons. Melee Attack Roll: +7, reach 5 ft. Hit: 11 (2d6 + 4) Slashing damage, and if the target is a Medium or smaller creature, it has the Grappled condition (escape DC 14). The shrike can fly while carrying a creature Grappled this way.

Impale. The shrike slams a creature it is Grappling onto a spike of wood, stone, or bone within 5 feet of it. The target takes 15 (2d10 + 4) Piercing damage, the grapple ends, and the target has the Restrained condition until it or another creature within reach of it succeeds on a DC 14 Strength (Athletics) check made as an action to work it free.

The old ground

Lychfield

Gargantuan Monstrosity, Unaligned

Some killing grounds are used too often. Seeded and hatched and seeded again, year over year, the ground stops being ground: husk casings pack into strata, gravewax runs the seams, cinder warms the deep layers, and the field closes over its dead like a mouth. A lychfield is no line's work. It is sediment — all three lines' leavings grown into one organism the size of a churchyard.

CR: 16 (XP 15,000; PB +5)

Traits

Legendary Resistance (3/Day). If the lychfield fails a saving throw, it can choose to succeed instead.

The Field Itself. The lychfield is a stretch of ground up to 60 feet on a side. Other creatures can enter and move through its space, which is Difficult Terrain for all of them but Necrophores, and the lychfield’s attacks can originate from any point of its space.

Teeming. At the start of each of its turns, the lychfield regains 15 Hit Points unless it took Cold, Thunder, or Radiant damage since the end of its previous turn. If it drops to 0 Hit Points, it is destroyed, and nothing hatches from it.

Seeded Ground. A creature that dies in the lychfield’s space is taken into it and laid in at once, no Reaction required. After 1d6 + 2 hours, 1d4 larvae of a line of the Game Master’s choice climb out of the ground where it died.

Actions

Multiattack. The lychfield makes three Grave Surge attacks.

Grave Surge. Melee Attack Roll: +12, reach 15 ft. Hit: 20 (3d8 + 7) Bludgeoning damage plus 9 (2d8) Necrotic damage.

Exhale the Wake (2/Day). The field splits along old seams. 1d4 Cinder Nits, 1d4 Gravewax Grubs, and 1d4 Crypt Instars emerge in unoccupied spaces in or within 10 feet of the lychfield’s space. They act on the lychfield’s Initiative, taking their first turns immediately after this one.

Legendary Actions (3/round)

Immediately after another creature’s turn, this creature can expend a use to take one of the following actions. It regains all expended uses at the start of each of its turns.

Close Over. Strength Saving Throw: DC 20, one creature in the lychfield’s space. Failure: The ground closes on the target’s legs, and it has the Restrained condition (escape DC 20). The lychfield can’t take this action again until the start of its next turn.

Husk Burst. Dexterity Saving Throw: DC 19, each creature in a 10-foot-radius Sphere centered on a point in the lychfield’s space. Failure: 13 (3d8) Piercing damage as buried casings shatter upward. Success: Half damage only. The lychfield can’t take this action again until the start of its next turn.

Wakelight. Buried lights kindle under the surface. Wisdom Saving Throw: DC 19, one creature in or within 30 feet of the lychfield’s space that can see it. Failure: The target has the Charmed condition until the start of its next turn and must move toward or into the lychfield’s space on its turn if able. The lychfield can’t take this action again until the start of its next turn.
