The origin story of Caedon, villain of the Stormclouds/Harbingers fantasy series, and his brother Maeldoi, the Dark Rider.

The gwrgi are not werewolves. Not exactly. But the strict gwrgi discipline trains a gwrgi not to let his inner beast come out. What happens if he's taken away by a demon instead? One brother to the castle of the arch-demon mage, Gilles de Rais. One to the harsh discipline of the gwrgi capital—and all their suspicions. And when gwrgi brothers raised as enemies confront each other in rage, expect something a little monstrous. A little strange.
