Issa is the god of the Nyissans. His totem animal is the serpent. Even while he is physically present in the world, Issa spends long periods sleeping. Whilst in slumber, his manifestation is a large statue behind Salmissra's throne. When all the gods save Torak left the world, he gave the governance of his people over to his beloved high priestess, Salmissra, but neglected to prolong her life. A series of replacement Salmissra-s ruled in her stead, and also kept certain secrets such as the ability to summon a physical incarnation of Issa—calling his spirit into the stone statue. Salmissra eventually gets turned into a snake by the Sorceress Polgara.
