Dragon Age: Origins is a beautifully rendered fantasy role-playing game with medieval European visualization for the game art direction. Combat is bloody and gruesome, filled with spraying blood and decapitation, but also stylized with special finishing blow animations. The game has various Downloadable Content adventures, items, and small expansions; and one major expansion/sequel, "Awakening".
This page of fantasy game art from Dragon Age: Origins: Awakening features Vigil's Keep, the Grey Warden protagonist's headquarters during the Awakening expansion. The deep basement and its strange locations are explained as a holdover from the Keep's history of fortresses razed and rebuilt at this site. From there, the darkspawn are said to have tunneled in from the ancient highways or Deep Roads of the dwarves.
