Oh, splendid. I love this stuff.
I really love the somewhat creepy 'Gothic Space-Catholicism' (for want of a better term) vibe that comes from the religious lore of modern era 40K. It is something that appeals to me much more than the original "Elves, Dwarves and Orcs in Space" thing we started with back in the 80s, and that they seemed to have dialled back quite a bit since then. I really must get and paint some Sisterhood figures myself one day. Probably not ever going to start playing 40K again, but I think I'd like to paint a few.
