I’m afraid I’m drawing a blank on a non-warden MCIT, but here’s an Origins era story I’ve been enjoying:
A blood Mage joins the Grey Wardens just before the battle of Ostagar. Cinna doesn’t know a lot of things, but she does know that she’s never done a smart thing in her goddamn life. Accidentally curing the blight along the way just so happened to one of the few good things.
And this one transitions into DA2 fairly early, I think, but it does start in Origins:
Catarina Lewis’ world turned upside down, so she ignored it. Until the day she found herself in Thedas. Now she is being swept into adventure after crazy adventure with friends who make life and death into a daily game. The more she learns of herself, the less certain she is of what she wants. Her knowledge of Thedas may come in handy, but everyone she meets is so much more than their character portrayals, and trust is easier said than given. The future she doesn’t know seems worse than the one she does– it is worth trying to change things, especially when she can’t know if it will be for the better?
