Excellent! I'm not sure how long Snape will end up staying - I don't plan on having him die this time around, which means he'll be having some kind of heart-to-heart of a Snape-like kind with someone at some point. That will instantly transport him back to proper!Asgard, I suppose. But! In the meantime, he'll be fighting giants and, most likely, a certain dark wizard who shall remain nameless (ie., Voldemort).
