Tulip - It's a planet. It's the second extra-solar planet that humans have colonized. And it's a beautiful place - all twelve square miles of it. That's all the bigger the main island is - the rest of the planet is submerged under a freshwater ocean. Yep, that's right - barely any salt, but plenty of water, and no continents. But like I said, it's a beautiful place. The one island, in fact, looks a bit like a flower as seen from orbit - that's just the pink residuals from the acidic lichen they had to sand-blast off the rocks before dropping down the settlements. Oh, yeah, the lichen isn't really gone - all the sand-blasting really did was drive the spores deeper into the pores in the rock.
