Yet the "real" "Den of Earth" is a fictional character created by Richard Corben and brought to life in the Leonard Mogel produced animated movie Heavy Metal"
From Wikipedia article "Heavy Metal (film)"
Den: Based on the original story by Richard Corben. Dan, a nerdy teenager voiced by John Candy, finds "a weird green meteorite" and puts it in his rock collection at home. Weeks later, during a lightning experiment, the orb hurls the boy into the fantasy world of Neverwhere, where he changes into a naked bald muscleman named Den (who doesn't want to walk around with his "dork" hanging out, and so wraps himself in a makeshift loincloth). Landing on a giant idol, he witnesses a strange ritual and rescues a nubile young woman who was about to be sacrificed to "Ullatec" (this may be the name of "Cthulhu" spoken backwards). Reaching safety, she tells him that she is from the British colony of Gibraltar, on Earth, and that her name is Katherine Wells. While she demonstrates her gratitude with sexual favours, they are interrupted by the minions of Ard, an immortal man who wants to obtain the Loc-Nar and use it to rule the world. He puts Katherine in suspended animation and orders Den to get the Loc-Nar from the Queen (the woman who performed the ritual). Den agrees and infiltrates the Queen's palace with some of Ard's warriors. He is promptly caught by the Queen's guard, but she offers leniency if he has sex with her. He complies, while the raiding party steals the Loc-Nar. Den escapes and, with the Queen and her forces in pursuit, races back to the idol, where Ard is attempting to recreate the sacrifice himself. Den rescues Katherine, and the Queen's arrival sparks a bloody battle between her and Ard (backed by their respective armies). Den ends the battle by recreating the incident that drew him to Neverwhere, banishing Ard and the Queen. Refusing the opportunity to rule, Den and Katherine ride into the sunset, content to remain in Neverwhere as heroes with idealized bodies.
