The Mindflayer's Psychogenic Stash

The psychic dampening field of the chamber collapses alongside the Mindflayer. As its purple form slumps to the cold stone floor, the party discovers a hidden compartment beneath its throne of smoothed obsidian. Here, the creature stored its most prized psychological tools and the spoils of its various conquests across the planes. The air smells of ozone and brine, lingering traces of the entity's presence clinging to the treasures recovered from the lightless depths.
