This concept art is of an area in the world of Dragon Age known as Hightown. Hightown is situated in Kirkwall which was once the center of slave trade in the Tevinter Imperium. The town came to be from an old quarry where slaves would labor away; the area in and around that basin is called Lowtown, and is populated by the poor. The area above the basin is so happily called Hightown and is home to the wealthy.
From the upcoming game, Dragon Age II, set to be released March 8, 2011
