The Spiral Crown
A silver crown with a spiked halo, adorned with gemstones of all colors placed in a swirling pattern. Hidden beneath the Spiral Chapel in the Death Ziggurat ruins, in a circular depression in the floor below the painted galaxy of Heedless Creation. To reach it, the spiral-patterned metal disc (hidden in a compartment behind a mural of a priest gazing out over the Cosmos) must be placed in the depression and pressed. Pressing without the disc summons a lightning bolt for 2d4 damage.
Wearing the Crown: Lightning shoots into it and the wearer becomes a cosmic vessel, seeing strange and nightmarish visions of the infinite, collapsing Cosmos. The wearer is allowed at most three DR12 Presence tests (one per round) to remove the crown. Should all tests fail, the wearer is irrevocably lost to the Cosmos.
Wearing the crown also reverses Akünh's channeling and quickly drains her health by d4 HP per round. She will instantly teleport and try to stop it.
Who made the crown, when, and which faction (the Cretun knights? a pre-Cretun cult? Heedless Creation itself?) is unwritten. The "collapsing Cosmos" visions are atmospheric but not detailed.
