You can choose the languages. If you don't have a story associated with her, i'd guess like most dark elves she had something to do with wizards of earth. Her alignement as well as being dark elf itself would point more towards Federation of Magic, the rather dark and malicious magicians. She can be a spy or an emmisary for the Federation, or she could have not liked them and instead gone to hang out with Tolkeen mages.<br/>The Tolkeen mages themselves are a rather peaceful and non-violent group at the beggining, but as the war goes they seek all allies they can. Dark elves are hardly considered 'bad' when even daemons are sought for the war with Coalition States, and Tolkeen can offer a lot of knowledge and magical artifacts for payment. There's also a matter of Coalition States killing elves and other sentinent magical creatures like they would be mindless monsters, so desire to protect the likes of her, or getting stranded in the middle of the war with no way to get home could be her reason to be involved. I'm not forcing you to actually have alliegance towards Tolkeen, but most of the times it won't matter for nobody if you aren't.
