For more than a thousand years the Dark Citadel guarded the mountain pass between Orcs and Men. After many attempts to lay siege to the citadel the Dwarven defenders finally were overwhelmed. It is said that mighty warrior holding a black spear given to him by his god led the attack and sacked the fortress. Now nothing but ruins remain. The Orcs and Goblins seem to have lost interest in the place. Rumors persist, however, about the riches left behind in the caverns below the citadel. The Dwarves were known to produce gems which they sold all across the land from mines below the citadel. This is a Mega-Dungeon. However, it is not your standard, Mega-Dungeon. This one is more horizontal than vertical. It follows a river deep into the earth reaching the Underdark and other foul places beneath the surface. There are 25 "levels" and 30 maps provided. Quite a few new magic items and new monsters are also offered.
