Lonely Land is a tear-shaped region in western Acirca that is home to the Dimmons. Lonely Land is always cast in a blue light, due to the magical filarmium lightbulbs built and strung abundantly throughout its hills. It is a dangerous place, as anyone who enters Lonely Land is magically separated from their companions. Furthermore, drinking from the water of Lonely Land causes unwitting travelers to fall victim to a curse, wherein the person turns blue and begins crying and babbling incoherently.
Lonely Land is "ruled" by the Brain Child, who has constructed all of its lights and towers, as well as the Land's mechanical creatures<ref>http://www.rice-boy.com/see/index.php?c=130</ref>. He lives in a large tower built around a black tree<ref>http://www.rice-boy.com/see/index.php?c=138</ref>.
Father Dimmon also is a powerful force in Lonely Land-- although he has been nailed to the ground, Father Dimmon still maintains control of the Dimmons. Nonetheless, Brain Child is able to trump Father Dimmons' commands when confronting groups of Dimmons.
