The second companion of the last Origins DLC is a human mage called Finn:

Finn is a young mage from the Circle of Magi in Ferelden. He considers himself the Circle's best linguist and foremost expert on ancient Tevinter history–even if others might consider him more of a bookworm, a recluse that spends all of his time in the tower's dark library. Finn is the unlikeliest of adventurers... but it may come to pass that his academic expertise will force him to out of the library and into an adventure where his arcane might is the only thing that stands between him and certain death.
