The Desert People live in the land of the diseased. They worship the God of the Fire and Roa.
During the events of Yor, the Hunter from the Future (1983)
Yor, the Hunter arrives at the land of the Desert People who attack him with flaming sticks. They capture him in a net and a voice calls out to bring Yor to her. He is then brought to Roa who tells him she came to the land of the Desert People with a group of people who were trapped in ice. She tells Yor that he is to be sacrificed to placate the gods. Yor is brought to a stone alter to be sacrificed as Roa watches. He breaks free and uses the sacrificial sword to fight his way free, taking Roa with him. As he does, the cave starts to collapse. Yor throws the sword at the last Desert Person blocking his path and exits the cave as Ka-Laa and Pag arrive.
