Nergal

Nergal is the twin sister of Kyhulla (formally known as Sisk'rostar). Both gods were created to be protectors of life shortly after the formation of Gadriel.

Over time Sisk'Rosham became bitter, everything they created eventually died, decayed and faded into nothing. Seeing that life was an illusion Sisk'rosham became Nergal sire of the dead.

During the dawn wars Nergal needed powerful allies and formed an alliance with Asmodeous ruler of the abyss, they sealed their alliance by having a child which they named Orcus.
