Aliens 
Fraal Human Sesheyan T'sa Weren Others
The T'sa are the only other space faring technological race and have the most colonies and advanced ship technology out of the races. They are also surprisingly long lived despite a tendency to take risks just for the fun of it. The T'sa have what is perhaps the strangest home world of any species; mostly because its their fifth. They left numbers one through four out of boredom and a need for change. They are also likely the only race to send real estate salesmen along to investigate colony worlds and give a sales pitch on it's potential of being a new home world. The original T'sa home world also has some surprisingly advanced technology, but mostly weapons and shielding devices that no one remembers how to run any longer.
T'san society is set up as more of a controlled anarchistic monarchy with a democratically elected advisor to the ruler. Don't worry if you don't understand that -- most T'sa don't either, they just live with it. Previous regimes have been either a) too strange to work or b) genocidal or c) religious. Not that the T'sa have any problem with religion, its just that their religions tend to be really, really strange and bizarre. Surprisingly, they have no oddities that could be explained by another race that the other races know of.
HISTORY (As known by humans): The T'sa had their own 6 world empire when humanity found them, as well as ships capable of speeds almost equal to the speed of light. Humanities terraforming technologies, given a strong boost by Fraal environmental adaptations, tend to be very helpful to the T'sa, who exchange their own space-faring technology for it. The T'sa prove to be very adaptable to human ways and give humanity some very good advice on colonising other worlds. The T'sa also had visited the world of the Weren and were teaching that species space travel.
The T'sa are suprisingly long lived and that combined with a strong curiosity led them to the stars when humans were just learning to read. However, they tended to explore and settle worlds very thoroughly, which explains their relatively slow expansion rate. Or at least that's what they tell the humans . .
