The Shadow of Bukrai, also known as the Breath of Klyss, is a horrific ethereal phenomenon, a malign energy emanating from Bukrai itself. The Shadow is the basis of existence for Morgath’s undead servitors, the Amorvrin and Gulmorvrin. The Shadow of Bukrai is the deadliest of foes to mortals. There are many dangers and foul creatures to destroy the flesh, but nothing else in all Kelestia has the power to destroy immortal souls. Worse, if a person is sacrificed by Morgathian cultists, the destruction of the eternal soul in the primal chaos of Bukrai is merciful. More often the soul is fed to Bukrai, while the body lingers as an undead Gulmorvrus.
