You are a Grey Warden, one of the last of a legendary order of guardians. With the return of mankind's ancient foe and the kingdom engulfed in civil war, you have been chosen by fate to unite the shattered lands and slay the archdemon once and for all.
In every origin story, the player is introduced to Duncan, a Grey Warden who is trying to find recruits to join the order. By the end of their origin story, the player's character is selected as a potential Grey Warden, and leaves with Duncan.
The player and Duncan journey to a fortress called Ostagar in southern Ferelden, to join Cailan, the King of Ferelden, and Loghain, a legendary general and Cailan's father-in-law. The three leaders plan to make a stand against the encroaching Darkspawn before the Blight can overwhelm Ferelden. Duncan can sense the influence of an Archdemon, a god-like being hosted in the body of a powerful Dragon that commands the Darkspawn, which means that this would be the first true Blight in over 400 years. It is of utmost importance that this Blight is ended before it can gain momentum, as previous Blights have left Thedas all but in ruins.
