He could not see Ciara, who was behind him, but he heard the metallic clashing of her mail and one small, whispered cry, and he knew that she had fallen, too.

The glowing creatures surrounded him. He saw their bodies bending over him, the frosty tendrils of their faces writhing as though in excitement or delight.

Their hands touched him. Little hands with seven fingers, deft and frail. Even his numbed flesh felt the terrible cold of their touch, freezing as outer space. He yelled, or tried to, but they were not abashed.

They lifted him and bore him toward the tower, a company of them, bearing his heavy weight upon their gleaming shoulders.

He saw the tower loom high and higher still above him. The cloud of dark force that crowned it blotted out the stars. It became too huge and high to see at all, and then there was a low flat arch of stone close above his face, and he was inside.

Straight overhead—a hundred feet, two hundred, he could not tell—was a globe of crystal, fitted into the top of the tower as a jewel is held in a setting.

The air around it was shadowed with the same eerie gloom that hovered outside, but less dense, so that Stark could see the smouldering purple spark that burned within the globe, sending out its dark vibrations.

A globe of crystal, with a heart of sullen flame. Stark remembered the sword of Ban Cruach, and the white fire that burned in its hilt.

Two globes, the bright-cored and the dark. The sword of Ban Cruach touched the blood with heat. The globe of the tower deadened the flesh with cold. It was the same force, but at opposite ends of the spectrum.

Stark saw the cryptic controls of that glooming globe—a bank of them, on a wide stone ledge just inside the tower, close beside him. There were shining ones on that ledge tending those controls, and there were other strange and massive mechanisms there too.
