The bit about interacting soldier-to-soldier instead of soldier-to-captain was one thing I was thinking about. In the case of the former they’d probably develop more of a sibling-like relationship instead of just a commander (protector) to soldier (ward) type of thing. Especially considering he’d know she was the heir of Jehanna he’d likely do a bit of the ‘stay out of harm’s way’ type of thing. What I think would work nicely would be—

(Depending on how you want her to be make her 19/20/21/22)

864 – Ismaire joins the guild. (She could be 12/13/14/15); Captain would be 21
867 – Major destruction of most the troop, Captain (24) inherits position of leadership. Ismaire could be 15/16/17/18

This would leave four years between then and the start of the story. I was planning on having my thief character have joined after her and be a quite young/rookie type of member, but I can edit it if you’d like her to be the newest. I’ll also be playing three members, just for notes: the Captain, a Mage-type, and a thief; If you have no objections of course. If you make her 19 or 20 he’s probably going to be a bit more protective of her than if she’s 21 or 22 – Since if we go with the above mentioned he would have first meant her when she was quite young. Or if you’d like her to be younger she could have always joined 865/866 to age her up a little. What do you think?
