The Fate of Thorbardin

The battle for the kingdom of the dwarves comes to the door of its mad king...
Brandon Bluestone has finally cleared his family's name and rallied the nation of dwarves. Now one great task remains to him: he must open up the greatest of the dwarf nations, Thorbardin, which has been sealed against the outside world by the edict of a mad king.
Aided by Gretchan Pax, a mighty priestess, Brandon leads an army to the north gate of Thorbardin. The hill dwarves and mountain dwarves strive to bury longstanding enmity and form an uneasy alliance against the King of Thorbardin and his potent magical minions.
