Drasmyr by Matthew D Ryan
The vampire Lucian val Drasmyr, the protector of an ancient talisman of great power, is drawn into a conflict with a Wizards Guild when he kills the head wizard of the guild and tries to cover his tracks with a fire.
Coragan the Bounty Hunter and his compatriots are hired to find out what happened to the now dead guild master. Their investigation leads them to the vampire’s castle, but, overmatched, they are forced to flee.
The vampire, knowing his secrets have been exposed, begins a relentless assault on the guild.
Together with the head wizards of the guild, Coragan and his companions prepare a trap for the vampire. But they must have care, lest they deliver the creature’s power to a secret insidious evil rising amongst them.
