Deep beneath the mountain fortress of Skullcap, legend has it, are the remains of the dark wizard Fistandantilus and the path to the gates of the dwarven kingdom of Thorbardin. Buried somewhere along that perilous path is the magical helm of Grallen, son of King Duncan, tragic hero of the Dwarfgate War. The finder of Grallen's helm, it is prophesized, will be rewarded and honoured by a united Thorbardin -- but he will also open the gates of the realm to fresh horror and chaos.
