Tenebres takes place in present day and focuses on the hidden society(s) of magic and monsters.

Characters can vastly range in appearance and abilities; many of the rules are set as suggestions rather than guidelines. The one thing to keep in mind in regards to looks is that if they interact with common folk they need to be able to "blend in" which can be achieved in a variety of ways. 

While there are some classifications that entirely define some characters in what they are, there are other circumstances where a character can fall into multiple categories. In these instances, there is usually one that represents them more than the other. 

Generally speaking all potential types of magic are fair game in Tenebres. The only exceptions are time and dimension manipulation, which are strictly prohibited by a common code kept by most Magi.
