Warhammer 40K's Adepta Sororitas: Nuns with Guns
In the "grim darkness" of Games Workshop's Warhammer 40K universe, "there is only war." Lucky, then, for the Imperium of Man that the Adepta Sororitas are on their side.
In the books, video games, table-top games, role-playing games, and graphic novels, these "Sisters of Battle" are the military arm of the Church of the God-Emperor of Mankind, and as such are charged with routing out witchcraft, heresy, and defending the shrine worlds. Organized into quasi-medieval Orders Militant, these battle-armored nuns and the cleansing fire of their flame-throwers have been a popular fixture in the WH40K canon since the game's genesis in 1987.
On the convention floor, cosplayers take advantage of the varied color schemes of the six different Orders Militant to spice up the flowing tabards and rigid armor of their particular Sister's uniform. Different ranks and functions, as well as weapons and "relics" (jewelry) all lovingly detailed and depicted in the gamers' manuals, offer additional nuance and variation. (Remember that all WH40K characters start off as wargaming miniatures, and the painters of such have an even greater eye for and obsession with detail than even cosplayers!)
Showing their devotion here are Illisia Cosplay, on the homepage and below left, DuckyJessica, above, Yin Han, below center, and Cosplay Lala, below right. Above right, cosplayer QuailChick finds some quiet shrine time alone.
If all this makes you want to start researching the Orders of Adepta Soritas for your next cosplay, we can't blame you. But be warned: It's NOT the cosplay to choose if you think you might be in a hurry to go to the bathroom. Nothing illustrates that better than the video below of an elite Celestian (complete with jetpack) at SVSCon in 2013...
