Skatsim
From Diablo Wiki
Skatsim was the religion in Kehjistan prior to the rise of the Zakarum, and is thusly known as the "Old Religion".
Though Skatsim appears to have been forgotten since the rise (and eventual corruption) of the Zakarum, there are a handful of Skatsimi artifacts that remain in the jungles of Kurast. One such artifact is a holy dagger known as the Gidbinn, which held powerful magic, held by servants of the Zakarum to prevent the enemies of the Prime Evils from reinforcing the warding spells that kept the jungle-hell from claiming the Kurast Docks. Another was the Black Book, written by a sage named Lam Esen, who studied Skatsimi rites and the effects of the Prime Evils on the world; the book was considered heresy by the Zakarum and found its way into one of the abandoned, ruined temples around Travincal.
The Taan Clan use Skatsimi rites in their magic. Ormus was a member of the Taan who resided in the Kurast Docks, and was able to invoke the Skatsimi rites, using the power of the Gidbinn, to strengthen the wards that protected the dockside.
