Sounds good. I'm also thinking of having one of the knights die during the first battle. I'm debating between either Tomas or Alan. Tomas dying would put more strain on Penelope as she'd be Mia's only lieutenant and Mia would be pretty devastated over his death. Alan dying would be sad for Gavin mainly and Penelope would definitely be there for him which could eventually lead to him misreading her feelings after his grieving. 
Idk I'm leaning towards Tomas right now but I'm also open to other ideas!
