Lorithon is the name of the planet near the outer rim of Airibron that was created by Lorthien during the Divine Age after the War of Behemeron. The planet was created from the body of the envious part of Velii, or the dragon-god Yulfgorn after he swallowed the malevolent part of Velii (Behemeron). The hero and son of Lorthien, Dsmir, fought the dragon and eventually tamed Yulfgorn and rode it when the dragon ate Behemeron. Dsmir killed the dragon and its body fell where it came to rest in the center of the galaxy. Lorthein imprisoned Behemeron by turning Yulfgorn's body into the planet Lorithon with the demon trapped at the core in the six layers of Yulfgorn's fiery heart (now called the Six Planes of Hell). Lorithon was named by outside entities after the First Dweller, or god, Lorthien,
