30k bits plus possessed equals Word Bearers Gal Vorbak for my aspiring Heresy era army. The actual models are pretty sexy but they're stupid expensive and don't appear to have a lot of different poses which drives me apeshit. I also have a crippling inability to do anything without converting it at least a little bit, so here we go, lol.
If you haven't seen the rules for the Gal Vorbak you really should, they are the first possessed marines and holy crap they are crazy good.
