This Is just the basic fluff. Ill get around to making a story and such later...

The 671st is a regiment based on the planet Carssius, Located at the end of the Centaurus arm of the milky way. The exact coordinates are x=1267 y=599. This is a slowly developing plains world, with large flat expanses of grass and other local fauna. There is no water on the surface, but there are many subterranean rivers. The colony has started to become a prime test facility for new weapons and technology. A special few colonists, soldiers and scientists have been granted access from the Techpriests on mars to begin creating and testing a new weapon guidance system.

The 671st is Carssius's only defense. However, the 671st is trained extensively in defense and military engineering. This has caused the regiment to have one of the smallest casualty rates in the entire Imperium. However, the 671st is not meant to be on the front lines, or leading a spearhead.

The planets only contact with xenos was with the eldar from the neighboring Alaitoc Craftworld. A scouting party of 10 Eldar rangers landed near the city of Thems. The resulting skirmish caused 2 671st Casualty's, and 3 wounded. The eldar in turn suffered 1 casualty. However, the Governor of Thems called a cease fire and entered peaceful negotiations. The result was a Peace treaty With the Alaitoc, and the Senate are in open negotiations for a trade agreement with the Alaitoc.

Well, thats my fluff. Tell me how you like it.
