The DOA website says "Your memories of the battle of Ostagar will haunt you for years to come. It laid waste to your order and claimed the lives of many great men and women."
"Now, there are rumours that a fellow survivor of the battle has escaped from captivity and is seeking the Grey Wardens' help. The time has come for the Grey Wardens to make their return to Ostagar and exact their revenge upon the darkspawn"
You'll be able to take on new enemies in the Battlefields of Ostagar, reclaim the lost arms and armour of a king and get a second chance to add dog to your party.
The add on will cost just 400 Bioware points. Bargain.
