"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 rumors 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."

Where and when can we get this? :)
