My plan for that is that something traumatic happened, either involving the gods of her old home, a natural disaster or a personal crisis. I haven't quite ironed out the details yet, but keep an eye out and you can see how it progresses ;3
Currently Ariadne is available for any types of plots. I am completely open-minded. She has never had much experience with magic or religion so I think I'd like her to meet someone skilled in magic and someone devoted to their religion so she can explore those aspects of Helovia. As it stands she will likely become a healer in any herd she joins.
If you'd like to throw your character(s) at her please let me know! She needs some lovin' <3
