Headscratchers / Warhammer 40,000: Rogue Trader

• I'm very confused about Sister Argenta's order. She says that she was sent to the Order of Our Martyred Lady and then assigned to the Orders Pronatus. I assumed that meant that she was assigned as a guard or escort, but apparently she's a Sister Pronatus. The Order of Our Martyered Lady is a Militant Order, and as far as I know, the Orders Pronatus are their own separate thing in the Adepta Sororitas. Am I missing something here?
  • If you pass a Lore (Imperium) check when asking about her Order, you can question her on exactly this and she'll explain her circumstances.
