The Forge of Fury is a dungeon crawl, or site-based adventure, that describes the stronghold of Khundrukar. The great dwarven smith, Durgeddin the Black, founded the secret stronghold within a great cavern system two hundred years ago when he and his clan were driven from their home by a horde of orcs and trolls. The orcs discovered the location of Khundrukar, Durgeddin's home, a century ago when they captured one of Durgeddin's clansmen. The orcs raised a great army that stormed the stronghold and slew the dwarves there, allowing the stronghold's five levels to fall into ruins. Now goblins, orcs and other monsters use the ruins as a base. Legends tell of the extraordinary blades Durgeddin forged in anger, enticing the player characters to come to the ruins of Khundrukar to obtain them.
