FE:A personal headcanon (spoilers):
Valarie’s mark was originally in her eye.
She didn’t really know why Plegians kept chasing her and her mother down, but suspected it was because of the mark.
At one point, her mother ends up badly hurt protecting her, and the guilt makes her do…this.
Unfortunately for her, the dragon’s heart is so strong the mark ends up reappearing, and this time, more visibly.
I find eyepatch MU particularly interesting. So many potential stories. I don’t know that marks can work like that, but that’s what I’m going to go with for this one.
Ah well. At least she’ll have a timeline where she won’t remember this happened. Otherwise, Valarie’s got some serious guilt issues.
Whyyyy do I do this to myself.
