I get the impression that Ovelia is some kind of rogue? Or at least starts out that way. Things obviously make an... interesting turn for her at some point.
Well she's something called a White Maegus. I don't know if you ever played or have seen the Final Fantasy Series, but it's a spin on a white mage. She's quite powerful in all forms of magic, since I felt that being able to completely mend somebodies wounded body with nothing but a spell deserved much more admiration that it gets. So a White Maegus needs to be able to understand and wield all elements of the world to capably harness the essence of life. She's about 200 years old too, so she's had a lot happen in her life. But where her story starts she's a wanderer that helps people in need while she searches for something very important to her.
