"I mean they are possessed by demons -- lose all sense of self and will over to what possesses them. But we're targeted because of our connection to the place where they originate, as it is the source of our magic."

A risk one takes, although one can't simply opt not to be a mage. Not without become Tranquil, and Lavellan would rather be dead than face that fate.
