Len Wein, Writer/Editor/ John Bsucema & Tony DeZuniga, Illustrators/ Glynis Wein, Colorist/ Joe Rosen, Letterer
Thor tries to find his father by again seeking the aid of Mimir. Unlike last time, Mimir now demands very specific payment for his services: The Cyclopean Ruby Eye of the Dragon Guardian of of Realm Below.
Thor finds the task dishonorable, but decides he has little choice. He journeys down into the Realm Below, adjacent to the territory of the Trolls and eventually finds the Dragon of the Ruby Eye. However, before he can fight the dragon, he discovers that his old foe Ulik has come here at the exact same time, seeking the exact same item.
Ulik claims that the survival of the Troll Empire itself depends on the procurement of the eye. Neither warrior is willing to forfeit the Eye, and so they fight each other for it. Ulik wins the fight, tossing Thor off a cliff into a lake of fire!
