Fragments Beyond the Veil #14
Trivia Question❓
Myconids communicate through a unique telepathic mechanism rather than spoken language — but what is the specific term for the spores they release to create a shared mental space, and what is the name given to the communal "dream-like" experience that results from it, during which Myconids can share memories, emotions, and even commune with the dead?

Monster of the Week
The Hollowcap Devourer
Large plant, unaligned
Deep beneath the earth, where corpse-mold climbs ancient ruins and the air tastes of wet stone, some Myconid circles whisper of a failed sacred experiment: a guardian-beast grown from fungal memory, cave rot, and the hunger of dead things. The result was the Hollowcap Devourer.
At first glance it resembles a massive quadruped made of layered shelf-fungus, root-cords, and pale chitin. Its “head” is a great hollow mushroom cap split open like a jaw, lined with frilled spore-gills that pulse when it breathes. Inside that cap is not a tongue, but a dangling cluster of bioluminescent feelers and bone-white feeding tendrils.
Some Myconids keep juvenile devourers as grove guardians, feeding them carrion and letting them prowl tunnel borders. Others consider them blasphemies—fungal hunger made flesh—because older specimens stop distinguishing between vermin, trespassers, and Myconids themselves.
A Hollowcap Devourer works well as:
a pet or guardian tended by a Myconid sovereign
a living siege beast the Myconids unleash when threatened
a rogue fungal predator that even Myconids desperately want destroyed
Visual depiction
A hulking, four-legged fungal predator lopes through the Underdark on root-thick limbs. Its body is armored in overlapping mushroom shelves like rotten pauldrons. Where a head should be, a giant hollow toadstool cap gapes open into a wet, toothless maw lined with ribbed gills and whipping white tendrils. Sickly blue spores drift from its body with every breath, and faint green bioluminescence pulses from cracks in its bark-flesh as it stalks through towering mushrooms and bone-strewn caverns.

Traits
Fungal Regeneration.
The devourer regains 10 hit points at the start of its turn if it has at least 1 hit point and isn’t in sunlight or has taken fire damage since the end of its last turn.
Spore Sympathy.
Myconids and other fungal creatures have advantage on Wisdom (Animal Handling) checks made to calm or direct the devourer, if such a check is appropriate.
Siege Maw.
The devourer deals double damage to objects, fungal barricades, and nonmagical structures of wood, bone, or packed earth.
Burrow Into Carrion.
The hollowcap devourer moves up to half its speed toward a corpse, a heap of fungus, or rotting organic matter it can sense. If it ends this movement within 5 feet of that material, it gains 10 temporary hit points.
Deathburst Spores.
When the devourer is reduced to 0 hit points, it erupts in a cloud of necrotic spores in a 15-foot radius. Creatures in the area must make a DC 14 Constitution saving throw, taking 14 (4d6) poison damage on a failed save, or half as much on a success. The area becomes lightly obscured until the end of the devourer’s next turn.
Actions
Multiattack.
The devourer makes two attacks: one with its Cap Maw and one with its Tendril Lash.
Cap Maw. Melee Weapon Attack: +7 to hit, reach 10 ft., one target.
Hit: 17 (2d10 + 6) piercing damage plus 7 (2d6) poison damage. If the target is Medium or smaller, it must succeed on a DC 15 Strength saving throw or be grappled (escape DC 15). Until this grapple ends, the target is restrained, and the devourer can’t use Cap Maw on another target.
Tendril Lash. Melee Weapon Attack: +7 to hit, reach 15 ft., one target.
Hit: 13 (2d8 + 4) bludgeoning damage, and the target must succeed on a DC 15 Constitution saving throw or have its speed reduced by 10 feet until the end of its next turn as clinging hyphae spread across its limbs.
Hunger Spores (Recharge 5–6).
The devourer exhales a 20-foot cone of choking spores. Each creature in that area must make a DC 14 Constitution saving throw. On a failure, a creature takes 21 (6d6) poison damage and is poisoned until the end of its next turn. While disoriented, it can’t take reactions and has disadvantage on opportunity attacks and Wisdom (Perception) checks. On a success, it takes half damage and suffers no other effect.
Bonus Action
Spore Step.
If the devourer is standing in dim light, darkness, fungus, or soft earth, it can move up to 10 feet without provoking opportunity attacks.
Combat Behavior
A Hollowcap Devourer fights like a territorial ambush predator.
It prefers to cling to cavern walls or squat among giant mushrooms until prey approaches. It opens with Hunger Spores, then isolates a smaller target with Cap Maw while battering defenders back with Tendril Lash. If wounded, it withdraws into fungus-choked terrain and uses carrion piles or corpse beds to recover.
When commanded by Myconids, it acts more like a patient guardian than a berserker. It blocks tunnels, breaks fortifications, and forces intruders into spore-filled chokepoints.
Myconid Relationship Variants
1. Grove Hound
A Myconid sovereign raised it from a spore-pod and uses it to protect sacred fungal gardens.
Change: it becomes neutral and won’t attack creatures bearing a colony’s spore-mark.
2. War Bloom
A desperate colony unleashes several half-starved devourers against slavers, duergar, or drow.
Change: add pack tactics and reduce HP to 110 if using more than one.
3. Rot-Saint Abomination
The colony tried to merge the memories of dead guardians into one fungal beast. It became unstable and now hunts the very Myconids that created it.
Change: its Hunger Spores also force a DC 14 Wisdom save or the target is frightened until the end of its next turn.
Adventure Hooks
The Missing Circle.
A peaceful Myconid colony has gone silent. The tunnels nearby are covered in feeding scars and pale mushroom growth. Their guardian devourer has grown enormous and begun consuming its handlers.
The Sovereign’s Weapon.
A Myconid leader offers safe passage if the party helps recover a stolen spore-urn used to control a Hollowcap Devourer before rival Underdark factions turn it into a war beast.
The Bone Garden.
Travelers disappear near a cavern of glowing fungal blooms. The devourer has been dragging corpses back to a ruined shrine, where something in the spores is making it smarter.
Using It at the Table
This creature works best in:
narrow fungus forests
corpse gardens
wet caverns with vertical walls
battles where terrain matters and visibility is poor
Pair it with:
Myconid adults and sovereigns
violet fungi
gas spores
spore servant thralls
duergar or drow hunters trying to capture it alive
Joke of the Day
Why don't Myconids ever get invited to Drow dinner parties?
Because every time someone asks them to "bring something to share," they release Rapport Spores and suddenly everyone's crying about their childhood trauma and nobody gets to eat the rothe steak.
Weapon Spotlight
Lash of the Remembering Circle
Weapon (whip), rare (requires attunement)
This living whip is grown from fungal fiber, root-thread, and pale chitin. Its surface is threaded with soft, fibrous ridges and faint bioluminescent veins. The material flexes like living root rather than leather, and the grip is firm and naturally contoured to the wielder’s hand.
You gain a +1 bonus to attack and damage rolls made with this magic weapon.
Lore
This whip was not made in a forge. It was grown in the hush of a myconid circle over many seasons, fed on memory, breath, and song. Its keepers used it to end violence, hold the line around a colony, and share warning without speech.
It remembers circles that no longer stand.
Those who hold it too tightly feel grief. Those who wield it to defend others feel steadiness return through the grip.
Properties
Colony Breath
When you hit a creature with this weapon, you can force it to make a DC 15 Wisdom saving throw. On a failed save, the first attack roll it makes before the end of its next turn deals only half damage.
Root the Aggressor
When you hit a Large or smaller creature with this weapon, you can force it to make a DC 15 Strength saving throw. On a failed save, the creature’s speed becomes 0 until the start of your next turn.
You can use this property 3 times, and regain all expended uses daily at dawn.
Hallucination Mist
As a bonus action, you release a hallucinatory spore cloud in a 10-foot-radius sphere centered on a point you can see within 30 feet. The cloud remains in that space until the start of your next turn.
Each creature of your choice in the cloud must make a DC 15 Wisdom saving throw. On a failed save the creature can’t take reactions, and choose one:
The creature’s speed is halved
The creature has disadvantage on the next attack roll it makes before the start of your next turn
You can use this property 3 times, and regain all expended uses daily at dawn.
Circle Memory
When a creature you can see within 30 feet hits you or an ally with an attack, you can use your reaction to reduce the damage by 1d8 + your proficiency bonus.
If the attacker is within the whip’s reach, it must succeed on a DC 15 Constitution saving throw or its speed becomes 0 until the end of its turn.
You can use this property 3 times, and regain all expended uses daily at dawn.
Spore Communion
When a creature fails a saving throw against one of this weapon’s properties, choose yourself or one ally within 30 feet of that creature. The chosen creature gains one of the following benefits until the start of your next turn:
Advantage on the next saving throw it makes
Advantage on the next attack roll it makes
Its speed increases by 15 feet
It doesn’t provoke opportunity attacks the next time it moves
This property can trigger once per turn.
Underrealm Bloom
While underground or in an area with abundant fungi or roots:
The saving throw DC for this weapon’s properties becomes 16
When a creature fails its save against Root the Aggressor, you can pull it up to 5 feet
When Spore Communion triggers, the chosen creature gains two benefits instead of one
Location
This weapon is most often found in places where myconid life once gathered or defended itself:
the center of a dead fungal ring
wrapped around the remains of a colony guardian
sealed in a damp shrine grown over with shelf-fungus
hanging from roots above a silent spore pool
It is often discovered dormant until exposed to breath and moisture.
Crafting
To grow this weapon requires:
living fungal fiber from a sovereign circle
root-thread taken from a place where two biomes meet
pale chitin shaped but never smelted
spores gathered during a myconid communal song
burial in warm soil for one full turning of the moon
The final step is awakening: the whip must be held within a living circle as memory is shared into it.
Destruction
The whip can be destroyed only if:
it is burned to ash in total dryness, and
the ash is scattered where no root, mold, or spore can grow
If even a living strand remains in fertile dark, it may grow again.
Quote of the Day
"Down here, beneath the weight of a million tons of stone, even silence has a heartbeat — and if you press your ear to the fungal bloom long enough, it will show you exactly how you died."
— Sovereign Phylo, Myconid Elder of Neverlight Grove
Player’s Corner - Subclass Spotlight Circle of Spores Druid
What It Does The Circle of Spores Druid channels the darker side of nature — decay, decomposition, and the strange life that blooms from death. Their signature ability, Symbiotic Entity, lets them expend Wild Shape to awaken a fungal aura: bonus HP, extra necrotic damage on melee attacks, and resistance to the damage that kills most things down here.
Why It's Interesting Most Druids celebrate life in bloom. Spores Druids understand that rot is the engine of all growth. They occupy a fascinating design space — part necromancer, part naturalist — and they're the only Druid subclass that genuinely thrives when things are dying around them. Halo of Spores chips passive necrotic damage just for enemies existing near you. Animate Dead (added to your spell list) means the fallen don't stay fallen.
In the Underdark You're not just playing a Druid down here — you're playing someone the Myconids might actually respect. Where surface Druids fear the dark, a Spores Druid hears the Underdark the way a Myconid hears a Meld: as a living conversation between what was and what grows next. Your character understands that nothing in the dark truly dies. It just changes form.
The sovereign doesn't see you as an outsider. It sees you as overdue.
Interesting Facts
Myconids Don't Actually Need to Eat — They're Running a Democracy Instead. Myconids absorb nutrients directly through their bodies, meaning they have zero survival pressure driving conflict. No hunger, no territory wars, no resource competition. This is why their entire civilization is built around communal melding and philosophical contemplation rather than conquest. They're the Underdark's only truly peaceful society — not out of weakness, but because they literally evolved past the need for violence.
Myconids Have a Word for Death That Translates Roughly as "The Final Meld." Because Myconids experience consciousness as a shared, collective thing through their rapport spores, they don't perceive individual death the way humanoids do. When a Myconid dies, its final spore release is considered sacred — a last broadcast of everything it ever experienced, absorbed into the colony's collective memory. Effectively, no Myconid is ever truly forgotten. Their dead live on as shared memory inside every surviving member of the circle, which is why they can also use spores to commune with deceased Myconids during a Meld. They don't mourn. They archive.
The Underdark Has Its Own Weather System. Most players imagine the Underdark as static and dead, but it has active ecosystem mechanics — fungal blooms that release spore clouds dense enough to choke visibility, underground rivers that flood entire passages seasonally, and bioluminescent "tides" tied to magical resonance rather than sunlight. Some passages are only navigable during specific fungal bloom cycles. The darkness isn't empty — it breathes.

Answer: to Trivia of the Day
The spores are called Rapport Spores, and the shared experience they create is called a Meld (or Melding). During a Meld, Myconids — and any creatures they choose to include — enter a wordless communion where thoughts and sensations flow freely. Myconids also use a second type called Animated Spores to reanimate the dead as fungal thralls, and Pacifying Spores to subdue threats — but Rapport Spores and the Meld are the heart of their social and spiritual life deep in the Underdark.

Adventure Hook of the Week
🍄
A Myconid spore courier arrives at the surface — alone, erratic, clearly damaged — releasing fragmented rapport spores that flood nearby minds with a single repeating vision: a vast fungal colony burning from the inside, and a sovereign screaming a name in a language no one in the party speaks. The creature cannot communicate beyond the vision, but pressed into its cap is a crude map etched in bioluminescent ink, leading somewhere deep in the Underdark that doesn't appear on any known chart. Whatever happened down there, the Myconids couldn't send anyone else — this one was the last.
Until Next Week, Wanderers...
Thank you for descending into the dark with us — the spores are still settling, and we hope a little of that fungal magic followed you back to your table. We'd love to hear from you: has your party ever encountered Myconids, and how did your players react to a creature that doesn't fight, doesn't flee, and just wants to meld?
Next week we go deeper. The Underdark isn't done with us yet — and what's coming out of the dark next has been forging grudges in magma-lit halls for centuries. Come ready. They don't forgive, and they never forget.
— See you below the stone.
