Ancient spires of fused glass rising from the Jahazai sands. The Ederhi raised them by magic in the age before the desert, and the Glassing sealed them: when casting turned lethal, the shapers died at their work and the towers fused solid around them mid-growth. The glass is unlike anything modern artisans can produce, harder and clearer, faintly luminescent at night. No entrance has ever been found because there is no inside to enter. Treasure-hunters who cut into the spires find only more glass, threaded here and there with the shadow of a shaper caught in the work, and an Ederhi script no living scholar can read.
