Forgotten Realms: Demon Stone is a video game that was released in 2004 for PlayStation 2, Xbox and Windows PC. It is set in the Forgotten Realms campaign setting for Dungeons & Dragons (D&D), but the gameplay only vaguely models D&D's structure. The story was written by R.A. Salvatore and features the voices of Patrick Stewart as Khelben "Blackstaff" Arunsun and Michael Clarke Duncan as Ygorl.
The hero of many of Salvatore's novels, Drizzt Do'Urden, makes an appearance in the game; he is a playable character during a portion of one battle.
Demon Stone was nominated for awards by the Academy of Interactive Arts & Sciences and the British Academy of Film and Television Arts (BAFTA).
There are three playable characters in Forgotten Realms: Demon Stone, each with his or her own unique abilities. The human fighter Rannek is a master of melee combat. Illius, a sorcerer, casts spells to protect his friends or attack his enemies. A half-drow, half-wood-elf rogue named Zhai easily vanishes into the shadows before sneaking up on her enemy for the kill.
The two villains are equally enemies of the heroes and of each other. The first villain —Ygorl—is the leader of the Slaad army. Cireka, general of the Githyanki, is the second. The game's introduction explains that the only thing keeping each of them from taking over the realm is their hatred of each other. Fearing that the realm would be at the mercy of whichever villain was victorious, the great mage Khelben Blackstaff sealed them both within a Demon Stone.
The story develops as the three heroes battle two orc armies near the jewel-rich Gemspark Mines. A great red dragon, sent by Ygorl, leads the group to these mines. Once there, they unwillingly release Ygorl and Cireka from the Demon Stone and into the world. The three heroes must undo their mistake by joining forces to right the wrong they caused ...before the realm is lost.
