The Kha'Zul are dying. Face to face with total extinction due to absolute female infertility, Kaelen has been dispatched as a Seeker across the stars. His mission: locate a compatible species to carry their lineage. Naturally. Without chemical alterations. When his sensors pick up a primitive, undocumented bipedal race calling themselves humans, he procures a specimen to begin testing immediately. Every threshold will be cataloged. Every limit will be tested.
