While I don't expect the core to be opening anytime soon, it would be nice to have a bit more of the storyline put in. i was thinking that there could be a mission where the spiral order scientists have created a small spacecraft that is just powerful enough to get to Cradle's moon and back. The order wants you to scout the moon, find out what it is, after all, why would an artificial planet have a moon? when you arrive, you find out that the moon is a prototype of cradle, or perhaps a failed first attempt.
