Dragonspear Castle is a ruined castle on the edge of the High Moor in Western Faerûn. The castle, once the home of famed dwarven adventurer Daeros Dragonspear, contains both a portal to a hellish dimension and a passage to the Underdark and has for years been a launching point for raids by evil monsters and marauders.
According to legend, Daeros befriended a copper dragon and built his keep around him in mutual protection. Daeros was often seen riding his dragon friend while carrying a 40-foot long spear (hence the castle’s name). The castle expanded to include several dwellings inside its walls, and a small dwarven village sprouted. Unfortunately, the dragon’s hoard was coveted by outsiders. A southern wizard’s manipulations led to the creation of the planar portal, the death of Daeros and the dragon, and the ransacking of the castle.
