Bloodwing

Walkthrough
Talking to the Royal huntsman in the Druids' Cave lets you learn about a garkain haunting the Swamp Cemetery. There are a couple of other garkains with him, and a couple of wraiths might join the fight, too, so using Vampire oil is highly suggested. The target is set apart by his name, Vesper, and like with other trophy quests, bringing his head to the Royal huntsman will earn you money and experience.
