[@AnaSilan Sunja] So I've been thinking about my creature, and is it okay to use a Wesen from the series Grimm? Probably something cat-like...

Wesens should be fine, as long as you make sure to make a mention of giving players a chance to not be controlled or something similar if the character you have in mind can secrete pheromones which enslave the victim's mind or the like. Other than that, they are considered Supernaturals so [@AnaSilan Sunja] shouldn't have a problem regarding Wesen.
