A humanoid android from a destroyed world lands on Earth in 1635. Six centuries, and 25 lifetimes later, he is tasked with saving an already crippled world from the Miranas. Like locusts, they travel from system to system destroying worlds, stripping them of resources, enslaving those they can use for work, and annihilating those who are unsuitable. As Admiral Arthur Martin, he must coax the scientific community into advances that allow him to build a force that can face the Miranas.
