if you dont know what a wolfwalker is i wrote (copied) a text to sum it all up Wolfwalkers are humans who possess the power to live in the forest as wolves while their bodies as human lay sleeping and they become wolf at night. When being bitten by a Wolfwalker, they will become one as well. It is unknown if one can be born a Wolfwalker.

or you can just watch the movie trailer idk https://www.youtube.com/watch?v=M72avENUrbY
