Conan (1970) #2
"Lair of the Beast-Men!" is written by Roy Thomas with art by Barry Smith and Sal Buscema. Our tale begins in frozen Aesgaard, with Conan looking over the lifeless form of a great white ape warrior whom he has just slain. But the barbarian has little time to puzzle over the beast-man's strange appearance as he soon spies a scantily clad woman running through the snow-choked wilderness. Unable to resist the temptation to follow and wishing to find shelter from the cold, Conan falls neatly into her ambush. Two more of the beast-men fall upon him and knock him unconscious. When he awakes, Conan finds himself in a prison cell in an underground city run by the beast-men the Land of Always-Light. Illuminated by strange phosphorous rocks, the city once belonged to a fallen elder race and now sees the harsh rule of King Gha-Kree. Human slaves are bred like cattle to do the beast-men's bidding in this nightmarish regime.
Conan, now chained for the first time in his young life, finds none of this city to his liking. And when he defies the beast-men's orders and tries to foment rebellion among the slaves, the Cimmerian is sentenced to die in the gladiatorial arena. Armed with only an obsidian spike handed him by Kiord, chief of the slaves, Conan faces a man-eating, albino lion. His bravery in the face of near-certain death inspires Kiord and the slaves to throw off their bonds and challenge Gha-Kree's rule. The act costs Kiord his life but in death, he becomes more of a king than the beast-man could hope to be.
