A race of beings who inhabit a different world but are quite similar to Earthlings. They were actually the original humans who tried to colonize Earth, but their colony ship malfunctioned and about 5,000 colonists were stranded on Earth. The colonists adapted and after time became "primitive", then rebounded to what we have today. And since in the last hundred years Earthlings have been trying to explore space, the original humans have begun to take notice.
The comic actually was planned to focus on an 8 or 9 person special ops team of the other planet's military, and their missions and such.
...Strong influences include Hitchiker's Guide, Star Wars, and Schlock Mercenary.
