Martel has...kind of an odd situation. The only loved ones of hers I am aware of aren't dead, while she is. I'm quite certain her parents are dead, but it's very possible they did not love her (this canon is brutal, okay). Otherwise she's the sort to love everyone and everything to some degree.

Then one of those specific loved ones is Mithos, her little brother who couldn't let her rest in peace and made existence hell for literally everyone for a few thousand years. She's been trying to not think about that part much because of the negative emotional effects, and I'm not quite ready for a huge backfire of this strategy just yet, but it can slip for anyone interested.

For good loved-ones memories, she has when her brother was an idealistic world-saving hero, and also her fiance Yuan (despite that pretty much being the only canon detail we have about that).

Bad... well, there's the horrible racism she faced throughout her life, her death which was related to the racism, her very long existence as an isolated consciousness while Mithos was systematically breeding and murdering people, and her canon point where she had an opportunity to try to get through to him and failed.

I'm wondering if I could work out something along the lines of her trying to use candles or something to honor everyone whose death he's responsible for, but that number is at least in the millions and she never really knew any of them.

ALSO I have not had her go by the Wall and see that his name is on there, so... there's another opportunity!
