Douglas Clegg - The Vampyricon Trilogy (Books #1-3)

1. Priest of Blood: Aleric the falconer meets his destiny in the bloody clutches of the seductive Pythia, sending him on a quest to unearth the mysteries of the ancient vampyre race.
Set in a dangerous world of ancient forests and buried kingdoms, of dangerous magic, and vengeance beyond lifetimes, The Priest of Blood is an epic dark fantasy of sword, sorcery -- and vampires.

2. The Lady of Serpents: The kingdom is home of the shadow-priests of the Veil, who whisper dark secrets to their new queen as white towers rise and forests fall. Heretic's burn on the Illumination Nights and an enormous arena houses endless gladiatorial blood-fights between vampyre and shapeshifter, and somewhere in the bowels of the castle sits an infernal machine for the torment of the vampyre race -- called the Red Scorpion.
In a medieval world, within a forgotten century where dark and dangerous magic lies hidden among lost cities of legend, Aleric the Falconer must escape his prison and find the vampyre Pythia, who has been taken prisoner herself halfway across the world.

3. The Queen of Wolves: In a world of gods and monsters, love and betrayal, handmaidens of Death, terrifying and beautiful vampyres, shapeshifting wolf women, shadow priests, epic battles, and magnificent underworld kingdoms, The Vampyricon concludes with a titanic battle fought between the Queen of Wolves and Aleric, Falconer, the priest-king of the race of vampyres
