The Witcher: Nightmare of the Wolf, a new anime origin film focusing on Geralt’s mentor Vesemir, has released a new teaser trailer, and also announced the English voice cast for the film.

This latest teaser begins with a scroll that reads “Witches are rogues without virtue, true diabolical creations, for only killing. There is no place amidst honest men for them…” It certainly seems true that they are made for killing, as the teaser shows Vesemir fighting horrific monsters, and even drinking a potion that looks to turn him into a monster as well. As an origin story for The Witcher, this teaser definitely focuses on the action in the new film written by Lauren Schmidt Hissrich and directed by Kwang Il Han.
