At the edge of the galactic disc, shadows gather. A spectral threat seen only by the Xaji, a race whose consciousness straddles the overworld and the dream. But the Xaji are far from united, their enigmatic founder lost somewhere in the celestial winds. Into the breach steps Threnody, the youngest of the species, who has as much to learn about himself and his kind as he does about the penumbral swarm bearing down upon this island of light in a dark cosmos. To defeat the anomalous enemy, he must descend into the murky past, learning truths which threaten to shake his foundations, and perhaps those of the galaxy. In the space between realms, the ghosts of eons past hold crucial answers. But they may not be the answers he wants to hear.
