Dungeon Siege III (DSIII or DS3) is an action role-playing game developed by Obsidian Entertainment and published by Square Enix for the PlayStation 3, Xbox 360 and Microsoft Windows.[5] Chris Taylor, the original creator of Dungeon Siege, served as an advisor during the development of the game. It is the third game in the series not to be developed by Gas Powered Games, (after Dungeon Siege: Legends of Aranna by Mad Doc Software and Dungeon Siege: Throne of Agony by SuperVillain Studios) and the first to be published by Square Enix after it acquired the complete ownership of the Dungeon Siege franchise. It was released on June 17, 2011. (wiki, 2014)

The game returns to the Kingdom of Ehb, which already featured as the setting of the first (but not second) game. Roughly 150 years after the events of Dungeon Siege, the 10th Legion, who provided stability and protection for the kingdom for 400 years, has almost completely been wiped out. 30 years before the game's setting, Jeyne Kassynder rallied the people of eastern Ehb and the Azunite Church against the Legion who she blamed for the death of the king (her father). Following a long and brutal campaign, she managed to kill the entire remnant of the Legion in a battle in the Rukkenvahl Forest and the royalist army of young Queen Roslyn has been driven deep into the mines of Glitterdelve, losing almost all of their power.
