Absolutely sane, thought not nearly as unfounded as you might think. I went down a similar path of thinking upon first arriving here. Any attempt at contacting or returning home doesn't seem to work, but I can't tell if it's just the magic of this world that is preventing it or if the magic of this world just thinks component materials must be incredibly expensive. Part of me is beginning to think it might be the former.
Anyway, hello. I am not an adventurer by any means, but I have found myself rather surrounded by them.
