Ronthil

Ronthil is a vampire in The Elder Scrolls V: Dawnguard. Like most vampires, he resides in Castle Volkihar.

Most likely a new initiate, Ronthil does not hold very much respect. So less that his sleeping place is not a coffin but a space behind an adjacent cupboard in the west of Castle Volkihar, behind the laying dead alchemist.

He is a merchant who is willing to trade with the Dragonborn. His interest seems to be pleasing others as much as possible, perhaps to gain other's trust and make a name for himself.
