This I know, but for the sake of the RP and the current situation she is currently in, that will change in time as she learns of all around her. [i](Character progression yay.)[/i]

I'm gonna have to call bull on that one.


I'm not a SoB player (they don't have [i]nearly[/i] enough codex circulation to attract me), but from what I understand the Sisters of Battle are the most fanatical arm of the Imperium, unflinching in their dedication and entirely unwilling to trust in the opinions of their enemies. They've had Ecclesiarchal dogma drilled into them for [i]decades[/i], they've had all sense of wrongthink flayed and burned out of their skulls, they're literally so devoted that their stalwart belief can cause [i]miracles[/i].

 The fact that a Sister of Battle would [i]change her mind[/i] about what to think about heretics, xenos, and traitors being heretical and traitorous speaks volumes about how out-of-character she is being. It's simply ludicrous. As said by one of the most infamous 'Thoughts of the Day' in the fluff, "an open mind is like a fortress with its gates unbarred and unguarded". 

If you want to play as something from Warhammer 40,000, I must say that you pick a character who isn't known exclusively for scourging and purging those who don't seem like they dogmatically follow their viewpoint. Go for an unorthodox Inquisitor, an Imperial Guardsman, a Space Marine, you could even go for a [i]Chaos cultist[/i]-- just make it logical for them to change their mind without needing a lobotomy. A Sister of Battle has no place in a setting outside the Imperium other than as a source of unending belligerence.
