Dragon Age Origins AU where everything is the same except your origin's temporary companion comes with you to Ostagar and joins the Wardens.
Dalish Origin? Tamlen is a menace. He's ready to fight anybody and everybody at Ostagar—even the King. Especially the shem king. Duncan hopes you keep an eye on him. It takes a lot persuading to get him to do the Dark Ritual. Easier if you're a female warden and you have a relationship with him, because he doesn't want you to die and he doesn't want to die. Will bitch a lot in Dalish—and so can you.
Mage Origin? Jowan never leaves your side. He doesn't want to leave your side, not after what you lost to help him. Wynne's glare has him cowering and using you for cover. He becomes braver, however, and when the march of Denerim comes, he is fully willing to take the final blow for you, his best and only friend.
Human Noble? Gilmore will doing anything to protect you, his friend, his lord/lady. He was fully willing to attack Duncan during the Joining if you had died. He gets along best with Alistair. If you become King or Queen, he becomes your bodyguard, and will follow you even to Vigil's Keep.
Dwarf Noble? Gorim will follow you anywhere. He's there in the Deep Roads, willing to die by his prince/princess, when you are both found by Duncan. He doesn't particularly want to support Bhelen for the throne, but if you do he will stand by your decision. If you had a child as a male, you can use the human way of making him the kid's godfather.
Dwarf Commoner? Leske had no choice when Duncan claimed him with you, but at least he's alive and breathing! And with you, too. During Ostagar, you can let him loose and he comes back trinkets and money. Doesn't like the whole 'saving the world' thing but, hey, at least they're looting. He really changes his tune if you make Bhelen king and, later on if Hardened, Alistair is made king/king with Anora because, wow, he's palling with royalty and getting the royal treatment! Fist fights Oghren a lot.
City Elf? Soris doesn't really want to be here. But you're here, and you've been his hero since you were children and he knows nothing can take you down, so he's a little bit comforted. He slowly comes into his own, being confident and sure of himself, and Shianni makes a comment about it and he says it's because he had you, his cousin, his friend, helping him. He and Zevran have a flirty relationship and, at the end if you didn't romance Zevran, have a hint of a relationship going on. Is fully willing to either die for you or do the Dark Ritual, because he wants to repay all the times you were his hero to be your hero just this once.
