Ok the stuff I have here is out of a thing I have called the Fluff Bible. It's currently in it's second version. None of this is from Index Astartes. It has a ton of stuff in it covering transport systems and STCs to tatoos and Assassins. If you would like a copy, just send me an E-mail at the address on the Home page and I'll send it to you. Unfortunatly hotmail cannot hold it. it's roughly 3000kbs. Portentmail and some others can recieve it so if you don't have a big enough account go get one from
The Races
Imperial Guard
Sisters of Battle
Imperial Space Marines
Chaos
Orks
Tyranids
