A Yank at Valhalla / The Sun Destroyers

A YANK AT WALHALLA by Edmond Hamilton: We stood petrified by horror in that foggy, stonewalled corridor, gazing cataleptically at the hideous creature whose reptilian head was rearing up from the curling white mists. Freya's slim figure had shrunk against me with a choking cry. Frey stood in front of us, his sword raised, his face wild as he looked up at the looming head. The hideous, abnormally huge coils could only be glimpsed in the mists beyond. But the giant spade-shaped head that hung above us was clear to our appalled vision. The enormous, opaline eyes were brilliant as they stared down at us. "The Midgard snake!" Frey whispered. "Jarl Keith!" Freya screamed to me. The great head of the snake Iormungandr abruptly darted toward us.
