[I'm running a SM game right now, and got a race of lizard-like people with a homeworld and everything in a binary star system. The empire name is Therataan Confederation, so T.C.S.S.=Therataan Confederation Space Ship]
"The Science Vessel T.C.S.S. Ganymede ceased transponder signals on January 21st, a mere 21 days after it's commisioning. A gunship squadron was despatched to the Tau Ceti system, in orbit of the fourth orbiting body, a nigh earth-like planet. There they detected life pods. Of the 237 crew members onboard the vessel, 57 survived. That of wich did not include the captain, Nlaso Urima. From the survivors reports, a unkown contact attacked them with lasers, thoroughly crippling them early in with a massive blast to their engineering section. As such they made haste to the life pods, but they could only hold so many. The Tau Ceti system. One jump away from their home starsystem. When the Squadron reached the homeworld and dropped the survivors off, they made contact with high command to inform them of their discoveries. The public was not informed.
As of current, a secret project codenamed "Black Sun" is being undertaken. It will utilize state-of-the-art sensor technology, and collier designs that have not yet seen the light of day. The planned expeditionary extermination force is as follows:
2x Gunship squadrons
1x Collier squadron
1x transport ship wich will transport 5 battalions to the planet to invade it.
If ground combat does not prevail, extreme measures will be taken. The planet will be bombarded to a frozen, radioactive wasteland by multiple missiles. The expected end of the conflict is estimated to be in one decade, hopefully. The government wants this to remain of utmost secrecy."
