Nethu is one of the Cytharai, the elven gods of the underworld. He is known as the "Keeper of the Last Door" and is said to guard the spirits of the dead until the Rhanda Dhandra, the last battle of the Gods. His accoutrements are a silver harp, which he uses to tease the souls of the dead from their bodies and heavy iron key which opens the door to the Mirai, the underworld. He is owner of a host of Dark Pegasi, which guard the gate to the Underworld. According to legend, the Pegasi feed on both the bodies and souls of their victims.
