Stone gives Watson a wry, slightly annoyed look because that was a rude question, but answers anyway, "The mentors say it was a scar formed in the womb. None one else in my bloodline has it, and I've had it from birth." He's used to it by now, but most people don't actually ask.

As for his actual question, Stone thinks a moment. "The Reaches where my colony lives is west of the Abascene peninsula, with a mountain range between them. There's a freshwater sea to the southwest, and a true ocean beyond that. The Reaches themselves are a multilayer forest of mountain trees. Trees that are--" He pauses, looks around, and gestures at the square as a whole. "--bigger around than this. Maybe two to three times bigger, and many many times taller. There are smaller forests built up on the platforms made by their branches."

Frankly, nothing like them exists on Earth.
