The Obsidian Lyceum
Knowledge bleeds purple light from the cracks of a dying mind.
An ancient underground academy carved from volcanic glass, now fracturing under the pressure of the Feywild. Shards of obsidian and pulsing violet energy dominate the landscape, creating a beautiful yet lethal environment for explorers.
The air smells of ozone and old parchment. The lighting is dim, provided primarily by the rhythmic, violet pulsing of ley-line cracks in the obsidian floors and walls. Sound carries strangely, with whispers from nearby rooms echoing as if they were right behind the listener.
☠Threat
The Arch-Overseer Malakor has survived within the rift, his physical form replaced by a chassis of sentient obsidian and Fey-energy. He seeks to finish his original experiment, which would bridge the Lyceum permanently to the Feywild, effectively deleting the surrounding miles of the Material Plane. His clockwork sentinels and the echoing ghosts of his staff guard the deepening levels against any interference.
History
Built centuries ago by the Veil-Shatter mages to study planar convergence, the Lyceum was the world's premier center for arcane engineering. A catastrophic experiment aimed at harvesting Feywild energy backfired, trapping the faculty in a half-material state and infusing the walls with erratic magic. The academy was sealed to prevent the rift from consuming the surface, but the obsidian doors have recently begun to weep purple light once more.
