Grim Batol... Its dark legacy is rooted in Azeroth's shadowy past, but most know it as the site of a terrible tragedy - a fortress where vile orcs maimed and killed the offspring of the Dragon Queen, the noble Alexstrasza, turning them into instruments of war. Of course, a squad of heroes led by a mysterious magician named Krasus defeated the orcs and freed the dragons from captivity, but the cursed mountain, the ruined citadel, still towers above the expanses... But Krasus, known to some as the red dragon Korialstrasz, feels: evil Grim Batol again raises his head, again threatens what is dearest to him in the world. This time he is determined to take the path of evil himself, but Krasus does not even suspect that his quest will lead others to Grim Batol, reveal a terrible secret that can not only destroy them, but also mark the beginning of a new era - an era of horror, darkness and destruction.
