Forgotten Realms: Demon Stone

Three adventurers who meet by chance find the Demon Stone, an ancient prison that shatters before their eyes. The evil imprisoned within is unleashed and the two nefarious spirits of a Githyanki General and a Slaad Lord threaten the world anew. You control three heroes: the fighter Rannek, the wizard Illius and the villain Zhai, who each have unique spells. Switch between them to use their abilities to your advantage. As the game progresses, your heroes will reach higher levels, learn new skills and obtain powerful items. To stand even the slightest chance of victory against the evil you're up against, you'll need them all.
