The Galactic Core Corps collects recently departed minds to augment prepared hosts on back-up planets, such as Icarus, the Planet of Lost Things, near Sagittarius A*.

One such host is a centaur variant, a harlequin equitaur of quadruped physique and sobriquet Non Sequitur. When he acquires his Earth-mind and equips the exquisite quantum-queueing quaternion staff Icosian, he's subsequently sent on a quest that requires the quick conquering a grotesque quagmire of squalor and iniquity. Along the way he befriends an ivory-billed woodpecker while learning portals and other scientifically realizable powers.
