An excellent Troika micro-sphere utilizing the colony ship theme. It recalled, for me, Heinlein's Orphans of the Sky. I could easily run a handful of sessions with this and  bit of invention. Great, flavorful stuff with just enough detail to take the heavy lifting off my shoulders. It has three backgrounds, a couple of monsters, a list of "Things to Do" (basically session plot hooks), and even a few spark tables for things like jobs on the Negotium and names of corporations. I have no real criticism for this. It has a great look and reads well. If I'm being picky, I would have liked to see a graphic or drop cap or something on page 1. I felt a little thrown into it.
