"Give me that control box, Jarl Keith," he whispered in a weakening voice, "that I may open the gate far below and let the waters of the sea rush down into Muspelheim upon the atomic fires. It was my father Odin's order to me. Yes, the atomic fires will be smothered and their radiations will be ended. This will no longer be a place of eternal youth and warmth."

"But when the sea water strikes Muspelheim, there will be an explosion that will wreck this land!" I protested.

"And that, too, would be well!" Thor shouted, swaying. "Let the land be wrecked before Loki and the Jotuns reap fruit of their victory and become a dread menace to all the rest of Earth. It was Odin's warning — Loki must not be allowed to menace all the world!"

He fell heavily to the floor. But he raised his great head and his voice came chokingly:

"Give me the box!"

I heard the quickly approaching roar of Jotun voices from Valhalla's halls above. I heard the shriek of the last Aesir women being cut down by the followers of Loki. In my mind unfolded a shocking vision of Loki, using his overwhelming powers of evil science to dominate all the outside world. I sprang toward the silver control box and was turning to hand it to dying Thor, when Freya screamed.

A man burst into the chamber. Loki's angelic face was a hell-mask of rage. The sword glittered in his hand and his blue eyes were blazing.

"I knew the Aesir would seek thus with my own ancient handiwork to snatch triumph from me by destruction," he said. "But you are too late."

He sprang at me with tiger swiftness, his sword raised. I ripped out my own weapon, but Loki's blade was already stabbing through my shoulder like a white-hot iron. I reeled, senses failing from that agony, dropping the silver control box. Freya darted forward with a wrathful cry, and I saw Loki hurl her back against the wall.

"You have lost, Aesir!" taunted Loki maliciously. "Asgard is mine, and the last Aesir falls to the swords of my Jotuns."
