True Vryloka would make a good cavalier, it would be a strange mix, the virtue loving Cavalier with his radiance powers and the vampire like Vryloka. Actually I'm pretty pleased with the Vryloka's flavour. Instead of stealing the vamps or damps flavour the have thier own. The Vryloka aren't vampires, they don't seem to need blood to survive, they can walk around during the day just fine, yet they still gain vampire like power and can learn to draw substance from a foes death. Thier not related to vampires either like the dampyr either, its more like they used magic to steal the power of vampires. They're a race that survives by immatiating vampires.
