Description. Forged from refracted crystal and bound by planar resonance, Lightshard Wardens are silent sentinels left behind by the Prism Wardens. They defend calibration vaults with unwavering precision, reacting violently to destabilized illusions.
Mirror-Sight. The Warden can see invisible creatures as long as a reflective surface is within 15 feet.

| 14 (+2) | 17 (+3) | 16 (+3) | 7 (–2) | 11 (+0) | 10 (+0) |
Description. Fractal Lurkers are mirror-hopping predators that stalk the reflective vaults of the Keep. They strike from impossible angles, punishing those who dare to gaze too long into the glass.
Pain Reversal. The first time the Lurker is damaged by a creature each round, that creature takes psychic damage equal to half the damage dealt (once per round).

Description. These spectral remnants of the Fracture Choir drift in dissonant harmony, their voices echoing across mirrored vaults. Their song is not meant for mortal ears—and those who hear it rarely forget.
Flight of Voices. The Echo leaves a shimmering afterimage. Ranged weapon attacks against it have disadvantage.
Resonance Surge. When reduced to 0 hit points, the Echo releases a final hum. One creature in line of sight must make a DC 15 Charisma saving throw or suffer disadvantage on Concentration checks for 10 minutes.
Sonic Pulse (Recharge 4–6). The Echo emits a discordant wail. Each creature within 20 feet must make a DC 15 Constitution saving throw. On a failed save, a creature takes 22 (5d8) thunder damage and is deafened for 1 minute. On a successful save, it takes half damage and isn't deafened.

Description. A recursive predator born of planar misalignment, the Axis Mimic feeds on indecision and paradox. It warps time and choice, forcing adventurers to relive their worst outcomes.
Recursive Body. The Axis Mimic regenerates 10 hit points at the start of its turn if it took psychic or radiant damage during the previous round.

Slam. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 15 (2d10 + 4) bludgeoning damage.

✦ Choir Wail Node (Environmental Hazard)
Location: R5 – The Fracture Choir

- Be deafened for 1 minute
- Have verbal spell components fail for one round
Disabling It:
- Silence spell ends the node's effect for 1 minute

Challenge 10 (5,900 XP)
| STR | DEX | CON | INT | WIS | CHA |
|---|---|---|---|---|---|
| 14 (+2) | 16 (+3) | 17 (+3) | 16 (+3) | 15 (+2) | 14 (+2) |
Description. A distorted echo of a possible self, the Recursive Simulacrum is a mythic-level entity that mimics its enemies, disrupts time, and unravels memory. It is a reflection of what might have been.
Simulated Self (Mythic Trait, 1/encounter). The Simulacrum chooses a PC within 60 ft. and generates a distorted reflection of that character—copying one class feature, one weapon/spell, and up to 30 hit points for 3 rounds. The reflection mimics their movement and makes an identical attack each time they do.
Chrono-Desync Aura. Creatures within 15 ft. begin to lose temporal coherence. At the start of their turn, they must succeed on a DC 15 Constitution save or treat their initiative as 5 lower until the end of the round. Does not stack, but prevents reactions.
Multiattack. The Simulacrum makes two Refraction Strike attacks.
Refraction Strike. Melee Spell Attack: +7 to hit, reach 5 ft., one target. Hit: 16 (2d10 + 3) force damage. On a crit, target sees a flash of an alternate life or death—they suffer 1d10 psychic damage at the start of their next turn.
Mind Cage (Recharge 5–6). Target creature makes a DC 16 Intelligence save. On a failure, they are trapped in a mental loop—unable to distinguish turns. The target takes 4d6 psychic damage and cannot move or take bonus actions until the end of their next turn.
Legendary Actions (1/round):
- Shatter Echo (Costs 1 Action): Dispel a single illusion within 60 ft.—even beneficial ones.
- Glimpse of the Not-Path (Costs 2 Actions): One PC must describe a moment their character chose not to take in their backstory. The Simulacrum acts on it, gaining inspiration or one bonus action next round.
- Unwrite (Costs 3 Actions): The Simulacrum targets any one visible glyph, magical effect, or nameplate—temporarily erasing it from memory. The effect ceases to exist until restored via greater restoration or Void's intervention.
DM Note: The Simulacrum may emerge organically in late-stage dungeon areas, particularly if escalation is maxed or if a PC has begun mentally syncing with Void. It can act as a test, protector, glitch, or narrative shadow—entirely optional but highly evocative.
