The Abjurer's Sanctum Hoard

As the final protective sigil carved into the floor fades, the Abjurer falls and the three Helmed Horrors collapse into piles of lifeless plate. The treasury's inner sanctum is revealed, housing a collection of potent artifacts and raw gemstones used to fuel the magical wards. A crystalline chest at the center of the room hums with residual force energy, its lid slowly creaking open to reward the victors.
