Afraid not, truth be told. Not as far as I know. But quite a few others have, and I've paid attention over the past couple worlds when they begin talking about their homes and the people they've met.

The closest I get it seems, is my .. ahhhh, darker twin wandering around here. I'm uncertain if we're alternate universe versions of each other or something else, but one day I intend to find out for certain. When the world isn't trying to end and all.
