Though physically present in the world, Issa spends long periods sleeping, disguised as a large statue behind the royal throne of Nyssa. When all the gods save Torak left the world, he gave the governance of his people to his high priestess, Salmissra, but neglected to prolong her life. A long line of subsequent Salmissras ruled in her stead, each chosen by their resemblance to the original, and also given the ability to summon a physical incarnation of Issa. The last Salmissra is eventually changed into a snake and made immortal by Polgara.
