Welcome to Librarium Online!
Hello, I am getting back into playing warhammer, i used to play fantasy a little bit and now Im wanting to try 40k. Through a friend I acquired a small(ish) force of Deathwatch themed units, and I really like them but I want to expand and as far as I can tell the chapter that most closely relates to their style of play is Raven Guard, I like the way that the RG look, so I think im going to try and expand this force into a RG force in the near future.
