This is Ohritori Island, in the Ultern region. It's a nice place, but it's also a hub of space-time phenomena where people are sent through the stream -- drifted, that is -- and essentially trapped here. The people have been very welcoming and supportive, though, which is a plus. And you're likely to find people who look familiar and have oddly similar life experiences, but that's the nature of alternate timelines at work.
