I wheeled instantly to see what danger confronted her.

She was struggling as though in the throes of convulsions. Her face was contorted in horror; her staring eyes and the motions of her arms and legs were such as they might have been had she been battling with a foe, but she was alone. There was no one near her.

Jat Or and I sprang toward her; but she retreated quickly, still struggling.

Darting to our right, and then doubling back, she moved in the direction of the doorway in the castle wall.

She seemed not to move by the power of her own muscles but rather as though she were being dragged away, yet still I saw no one near her.

All that I take so long to tell, occurred in a few brief seconds— before I could cover the short distance to her side.

Jat Or had been closer to her; and he had almost overtaken her when I heard him shout, "Issus! It has me, too."

He went to the ground then as though in a faint, but he was struggling as Zanda struggled—as one who gives battle to an assailant.

As I raced after Zanda my long sword was out, though I saw no enemy whose blood it might drink.

Scarcely ever before in my life have I felt so futile, so impotent. Here was I, the greatest swordsman of two worlds, helpless in defense of my friends because I could not see their foes.

In the grip of what malign power could they be that could seemingly reach out through space from the concealment of some hidden vantage point and hold them down or drag them about as it wished?

How helpless we all were, our helplessness all the more accentuated by the psychological effect of this mysterious and uncanny attack.

My earthly muscles quickly brought me to Zanda's side. As I reached out to seize her and stop her progress toward the castle door, something seized one of my ankles; and I went down. I felt hands upon me—many hands. My sword was tom from my grasp; my other weapons were snatched away.

I fought, perhaps never as I have fought before. I felt the bodies of my antagonists pressing against me. I felt their hands as they touched me and their fists as they struck me; but I saw no one, yet my own blows landed upon solid flesh. That was something. It gave me a little greater sense of equality than before; but I could not understand why, if I felt these creatures, I could not see them.

At least, however, it partially explained the strange actions of Zanda. Her seeming convulsions had been her struggles against these unseen assailants. Now they were carrying her toward the doorway; and as I battled futilely against great odds, I saw her disappear within the castle.

Then the things, whatever they were that assailed me, overpowered me by numbers.

I knew that there were very many of them, because there were so many, many hands upon me.
