Mages in the new World of Darkness are able to manipulate reality to a fundamental level (depending on their depth of knowledge and abilities.)
Can a mage bestow a supernatural template on a normal human being, or remove a supernatural template that someone already has?
In other words: can a mage turn a normal person into a vampire, a werewolf, a mage (practically awakening a Sleeper), etc? And, in reverse, can a mage turn a vampire, a werewolf, etc back into a normal, ordinary human being? My guess is that yes, a mage is able to do this - question is, what Arcana and what level of power and knowledge allows it.
Am I right to suppose the above? (If so, where do I find the rules or implied rules for this?) If not, why not?
Please, cite official sources, if possible. (I'd be most interested in "non-godmachine"god-machine" answers, since I'm still not really familiar with that additionedition.)
