Áine.

Áine is a mage from Kinloch Tower. She was there during the blight and had Cullen as one of her acquaintances.
She fell in love with him but was too shy to say something about it. Nevertheless, he was in love with her friend Amell and didn't know she even existed.
A lot happened in their lives until they met again in Skyhold. And for the first time, the templar saw the mage as a woman and not as a charge.
