[@Bishop] Currently, no. The first reason is that I'm still figuring out how powerful magic will be, how directly related to radiation it will be, and how common it will be. A human who temporarily stops being human depending on the phase of the moon is on the edge of all of those rapidly-shrinking confines, so it would be unfair to let you keep writing a character who might be too magical for the final OOC. The second is that while Terra is a pastiche of hard fantasy tropes, there should be no direct transplants of these tropes without running them through an irradiated filter -- the Greens are descendants of mutant humans who do not necessarily act "orcish", the elves are all weird mute psychics, catgirls/satyrs/angels are all direct results of bestiality, etc.

A halfbeast who coincidentally happens to look like the 1930's wolfman would be fine, a human with an incurable disease slowly turning them into a wolf would be fine, a wolf given a human body who still thinks and acts like he's a wolf would be fine, but a straight-up werewolf is not. Hope I have answered your question.
