Xorn of Stafknir Hrerbjof

Xorn

In the Dawn War, the Dezellâm were sent to the Sands of Hell by the primordial Storralk. They were tasked with harvesting crystals growing from the bodies of xorn. Being a pacifist people, the Dezellâm followed catch and release procedures when they harvested the xorn's precious cargo.

Xorn of Stafknir Hrerbjof roam the shallow Underdark beneath the desert. Since they are not native to this plane, they produce a white crystal on their bodies that grows like cyst on flesh. Storralk learned from  Geb that the crystals are a variation of deep crystals and useful for holding psychic energy. Storralk wanted these crystals to help his troops against psionic heavy primordials that turned against him and to combat those angelic foes with great psionic potential.

In the Demon Spawn War, the Dezellâm used powdered deep crystals to fortify their ceramic shields. This powdered deep crystal is used when making ceramic, resulting in the material ceratimus. The krivian ghouls are thought to have learned the process of making ceratimus from Dezellâm tomes found in the ruins of Gallo-Bagd.
