Picture, if you will, a proud race of Minos. Living out there lives, oblivious to their surroundings. Until, one day, they realize there sun is about to explode and everything becomes a mad dash to leave there solar system and find respite on other planets.
Six Tetrinauts are sent to six different planets deemed terraform-able and to "ready" the planet for the impending mass exodus of Minos.
When the Tetrinauts arrive on the lush, fertile planet of Deneb, they are greeted with this...
The kingdom of the apparently equally as proud Denebians. Of course, this doesn't phase the Tetriminos. The conquest must continue. Poor Denebians.
I think they plan on them being a food source.
