The Lair is Griffin O'Conner's home and successor to his former home, the Hole. It is located deep within an unnamed desert.
After his previous home, the Hole is located by the Paladins, Griffin escaped and built the Lair, which served as his new home and hideaway. Over the years, he'd gather a small arsenal to help him in his one-man war against the Paladins. Eventually, he meets another Jumper named David Rice, who occasionally visits the Lair for Griffin's help. A group of Paladins (led by Roland Cox) tracking down David would discover Griffin's lair in an attempt to capture his [David's] girlfriend Millie Harris via device that can reopen jumpscars.
