well, there are the two planets; one is 'Primus' a planet of the Apes only in the Freelancer world. The other is a robot planet (forgot its actual name). On either planet, you cannot take jobs from the apes/robots. Nor can you buy items. There is also a very distant star, which, if you have the time to travel to it, is completely harmless. That is, you can pass through it without getting blown to bits. Other than that, the system is not much to look at. The other "Unknown System" (the one accessible from Omicron Alpha) is completely empty, as far as I know. It is impossible to travel through it, as the whole system is radioactive.

That second Unknown system you mentioned is indeed empty, and pink. You can actually travel through it just fine as long as you have enough nanobots. I circled the entire system just to be sure there wasn't something I was missing

Ugly pink place.

That's all you need...Nomad Weapons
