This
is a curiosity to say the least. Walking along and simply ending up in another place entirely. Appirition is terribly deliberate, not a magic that can be used by accident, which leads me to believe there must be another form of powerful spatial magic at work here, leaving my question to be who has the skill for such a thing. Further, I've come to the conclusion that this jump has not been simply over space, but time as well. I've no logical explanation for it at all, but the fact remains reality that this is what has happened.
Forgive my musing as I reason this out and do correct me if I'm wrong in my inference on the matter. What I ought to be doing is introducing myself. Remus Lupin, pleased to meet you all.
