[@Fairyfloss] 1.Any species is allowed, you can be an alien if you want. I'll even make exceptions for more godlike entities if they have a good story to them

2. It depends on what kind of Supernaturals and the person, some religious types might not like Demons and Vampires but might like Fairies and Angels

3. Humans can he mages, and again it depends on the mage. A Necromancer might be feared and with attempts on their lives for example while a healer or alchemist might be praised
