Hey everyone I was in the college of winterhold and something weird happened. I went into the hall of countenance and was talking to Phinis outside of his room. Than randomly a huge explosion occurred and knocked everything of the shelves. I looked behind me and all I saw was ghostly remains. Any ideas?

No idea.......the only thing i could think of is one of those enemies that appear right before labyrinthian.

It was like playing fallout 3 when you step on a landmine
