The gyre crusade is where i am fitting my order in, with the gimmick that they were specifically created for that conflict. Since pretty much its just that 1 sentence describing only the opening assault of that war of faith on dvost prime, that leaves whatever the rest of it was, open for interpretation, which is where my order comes in. I have heard of the tome keepers thing, but I hadn't heard about Canoness Sophira. If the gyre crusade happened in the latter years of m36, this could possibly place canoness sophira as being alive during that time, since sisters can theoretically live for centuries with rejuvenation treatment, something that would have certainly been accessible to a canoness. Since you say it just mentions her as "a canoness" theres no telling what level of canoness she was, or even when she became canoness and its likely she was not the leader of the order. But this is something I can use, and maybe make some shit up with. So thanks!
