The Gdornuu Vault
Blue light leaks from the floor while something enormous pulls once against its chains beneath the northern door.
The Blackreach Vault lies beneath a shelf of glassy stone, its rounded chambers cut into a natural cave and reinforced with white ceramic brick. Once a shared dormitory, laboratory, archive, and prison for the five White Asphodel schools, it now shelters undead scholars sustained by the aura of a captive star-born entity.
Cold mineral air presses through every chamber, carrying the smells of wet stone, lamp oil, old paper, and faintly sweet decay. Blue-white radiance leaks from cracks in the rock, while distant chains scrape at irregular intervals and dead voices murmur behind sealed doors.
☠ Threat
Gdornuu, a star-born magical creature, hangs chained in the deepest chamber. Its aura keeps the dead scholars moving and distorts memory, gravity, and spellcraft throughout the vault. Some undead retain enough intellect to restore the old experiments, while others seek the release rite, believing that Gdornuu's freedom will return them to life.
History
The Blackreach Vault was built by the White Asphodels, five secretive magical schools that borrowed their name from an old flower in their distant homeland. They carved the first chambers as a shared dormitory and archive, then expanded them into laboratories for forbidden necromancy. After an experiment involving Gdornuu went wrong, the alliance imprisoned the creature, converted the lower rooms into cells, and abandoned the vault when the schools turned on one another.

Quest Hooks
Quest giver: Hedra Pell, a soft-spoken archivist from the surface town of Neralu
A scholar's journal has surfaced in a nearby settlement, containing the first half of a release rite and the names of three missing apprentices. The party must retrieve the second half before a necromancer reaches the vault.
A sealed spellbook containing three fourth-level necromancy spells that can be safely cast once each
Quest giver: Torvik Kett, a hard-edged mine captain with a cracked brass prosthetic hand
Dead voices have begun speaking through wells and mine shafts near Blackreach, repeating the phrase, "Five must open what five closed." The party is hired to determine whether the phenomenon is a haunting, a warning, or a summons.
A claim to recoverable relics from the vault and 250 gold pieces
Quest giver: Geth Korran, a severe old battlemage who refuses to name his former school
A surviving member of the White Asphodels wants Gdornuu destroyed, not freed, and offers the party a weapon designed for the task. The weapon is genuine, but its use will collapse the vault's magical supports.
The Asphodel Starbreaker, a single-use weapon effective against aberrations and constructs
Corridor Notes
Five shallow copper inlays run along the walls, each marked with a different school seal. When a living creature passes, one line briefly glows and points toward the control center.
Small black handprints stain the stone at knee height, as though dozens of children tried to climb toward the dormitory. The prints end abruptly at the door to Room 2.
A broken speaking tube runs through the ceiling, carrying fragments of whispered lectures from the research rooms. Listening for one minute reveals a warning about the chained prisoner.
Iron rings and scraps of numbered parchment line the deeper corridors, remnants of the vault's prison period. Some rings tremble whenever Gdornuu shifts its chains.
