Antor Trellig, head of a ruthless interstellar syndicate, had seized a super computer with godlike powers, which could make him omnipotent. The Council offered master criminal Mavra Chang any reward if she stopped Trellig - and horrible, lingering death if she failed.

When the opponents were drawn across space to the mysterious planet, they found themselves in new alien bodies, and in the middle of a battle where strange races fought desperately, with the control of all the Universe as the prize.
