The Fright Knights were a faction of soldiers that were not ruled by a king, but instead by Basil the Bat Lord. The Fright Knights sets delved deeper into the supernatural "Fantasy" aspect of LEGO, featuring black dragons with fire-coloured wings, as on Draco the dragon and creepy trap-filled red-and-black castles, crystal balls, and Willa the Witch, a dark sorceress who was the real power behind Basil's throne. This theme could be classified as a sequel to Dragon Masters. Their headquarters was the Night Lord's Castle. It lasted from 1997 to 1998. Their motivation is unclear. They also had a small part of LEGO Universe, their uniform being an outfit on the game called "Bat Lord".
