Dragon Age: Awakening, New Character Velanna

So far the first bit of news that hasn't come from today's X10 event is that Bioware's announcement of a new character in their upcoming Dragon Age expansion.
Dragon Age Origins: Awakening is going to include several new characters when it comes out on March 16, one of which will be Velanna, who seems to be a mage of sorts.

There was no official statement with this video, so your guess on what kind of role this character will play is as good as mine.
