The so-called Wolfwalkers are individuals (most often found in northern parts of Faerun), with a werewolf as their ancestor. Normally, they would be the same lycanthrope as their relative, but they have upgraded their bodies with magic in order to gain control of the curse. This procedure requires a lot of knowledge and talent, at the same time being extremely dangerous. So normally, those people find an archmage or an archdruid, who could perform it safely. The downside is, the payment most likely will be pledging a life-long duty to their savior.
