I'm not 100% on if she is allowed to be a Bloody Rose or not, it obviously suits her personality. But the line that I made bold makes me think I can have one from a different order. But if that isn't allowed then I'll just go through and fix it.

Rank: Obvious – they can range from a standard Battle-Sister, down to a Novice Advance, specialist ranks such as Repentia, Dominion/Retributor (Heavy Weapons specialist) and the like are also allowed; [b]if your character is part of a different Order, then feel free to use Order-specific ranks.[/b]
