Vasily Lantsov was the eldest of the princes of Ravka and older brother of Nikolai Lantsov. He was the only natural son of Alexander III, King of Ravka, as Nikolai was considered to be the bastard of the Queen. He was the heir to the throne of Ravka before the attack on Nikolai's birthday party, where he was slain by the Darkling's nichevo'ya.
He was first mentioned in the first book of the trilogy, Shadow and Bone.
He is described by Alina as almost handsome, if it were not for the weak chin that he inherited from his father, and his eyes so heavy-lidded that it is hard to tell if he is bored or drunk.
- There were several Russian rulers named Vasily from the 14th to 16th centuries, which may have been the inspiration for Vasily Lantsov's name.
