OPTION A)
Aragon Aeducan
He is a dwarven noble with a heart of gold; equipped with a large round shield and a war axe. His love for his family is so extreme that others may not understand it completely.
He falls head over heels for Leliana and embraces the Maker and Andraste fully.
His trust, love, and loyalty for his friends knows no bounds.
*EXTREME SPOILERS IN THE SPOILER*
Aragon is the man who keeps everyone grounded and gives them all new hope. He supports Alistair for King even though he doesn't want to be because he's a good man. He refuses Morrigans ritual but begs her to stay; she obviously does not. Leaving Alistair and his beloved Leliana at the gates; he takes his group to the battlefield to die a heroic death.
*END EXTREME SPOILERS*
OPTION

Rituous Amell
A human male, circle mage. While the story of Revka is known; an Amell father is not named. Rituous is half Chasind and wields a large maul.
He revels in magic of all kinds and barbarism.
Personality wise, Rituous is dark, stern, controlling, and ruthless.
Always looking down to Jowan, he is shocked when he turns to Blood Magic and becomes in awe of the power it held.
In Redcliffe that power is offered to him and he takes it. He falls in love with Morrigan but lies to her and himself when he agrees that he feels love is weak. His story will take a darker turn and certain options that aren't available in Origins will be happening in his story.
OPTION C)
Blythe Mahariel
A male Dalish archer (specifically a longbow). He is cynical and cold but young enough for his beliefs to be influenced. More defensive around humans than any other species.
Zevran quickly gets his attention, being the only other elf, but it turns into something more. Blythe's story is more about discovery than the other two. In the end he realizes that humans aren't as bad as he made them out to be.
*EXTREME SPOILERS IN THE SPOILER*
Because he ends up getting close to Alistair his view on Morrigan becomes a bit skewered. The ritual is not done and Alistair sacrifices himself to save his friend.
*END EXTREME SPOILERS*
Also, all of them have different Awakening storylines :3 So please let me know which one you'd like to see. I'll be posting the DA2 options shortly.
