Her story is that there was a tribe of human barbarians that were close to the Latari. There was a prophecy that a child born of one woman from the tribe and a dark elf would one day rule elfkind. Dark elf meets up with woman, they have a child together, presumably with different intent for the child. Dad disappears, mom raises kid.
First Darkness happens, Uthuk kill mom. Kid wanders as orphan, spends years traveling the world, working on her powers and meeting people. Eventually goes to the Latari and manages to impress the king. Becomes his consort, inherits access to the Tear the Dark Elves left behind.
So, she's super old right? Over millenia?
