Otha was the Emperor of Zemoch and servant of the god Azash. Originally a humble shephard boy, he found the idol Azash had been imprisoned in, and by appealing to his cruel nature Azash convinced Otha to be his servant. Eventually with Azash's help he rose to be the Emperor of his people and was granted an extraordinary lifespan reaching across centuries. Bloated almost to immobility, Otha is killed by Azash in his own palace at the climax of The Sapphire Rose.
