"Where is the door out?" I demanded.
"Perhaps you can guess better than I have been able to. Even as you, I went from dark to light, found this ledge, but no return. When your mind-send came I hoped it would direct me to an exit. But that was not to be. You came to me instead/
"Where did you come in?"
Her nose pointed to the other end of the ledge, well away from the spot where I was still sure my door existed. I went there, again running palms and fingers along the surface, hunting the smallest hint of an opening. I still had the cutter which Maelen had used on the tangler cords. Perhaps with that, or one of the other tools from my belt, I could force a lock, were I able to find it. A forlorn hope, but one clings to such.
The humming from the globes was continuous now. And it did something to my hearing. Or was there a more subtle outflow rising beyond the range of audibility to affect my thinking? Twice I found I had halted my search, was standing, gazing down at the globes, my mind seemingly blanked out. It could only have lasted a second or two, but it was frightening.
Now I believed that the globes were generating a haze. The forbidding representation of the designs on them was fading. However, that concealment acted in a strange way, just the opposite of what one might expect. One could no longer see those monsters, their elongated jaws a fraction open, their formidable fangs revealed, yet there was the feeling that so hidden, they were more alive!
"Krip!" Maelen's thought-cry dispelled what was building in my mind. I was able to look away, turn my head back to the wall. But now I feared that a danger worse than imagination presented was threatening us.
Solid wall. I thumped it now with my fist as I went, my blows faster, more savage. All they brought me was bruises and pain. Until—I had carried in mind so sharply the thought of a door, the need for a door– my fist went through!
To my eyes the stone was solid, as solid as it had ever been. But my hand had sunk in up to the wrist.
"Maelen!"
She needed no call. She was already padding towards me. Door—where had the invisible door come from?
"Think door–think it! See a door in your mind!"
I obeyed her. Door—there was a door there—of course there was. My hand had gone through the opening. There might be an illusion to deceive the eye, but there was nothing now to baffle touch. I rested my other hand on Maelen's head and "we moved resolutely forward together into what appeared solid, unbroken stone.
Again we passed abruptly from light to dark. But also, as if a portal had slammed shut behind us, the humming was instantly silenced. I gave a sigh of relief.
"Is this your way?" I asked. Though how she could be certain of that in the dark, I did not know.
"I cannot be sure. But it is a way. We must keep together."
I left my hand on her head as she crowded against me. So linked, we went on, very slowly and cautiously, my other hand outstretched before me to warn of anything which might rise in our path.
Shortly thereafter I found a wall, traced along it until there was another way open to the left. Long ago I had lost all sense of direction, and Maelen confessed to a similar disability. We could do little until we found some lighted way. That we might not do so was a horror we refused to give mind-room to.
Whether the Thassa shared the ancient fear of the dark with my own race, I did not know. But the sense of compression, of stifling pressure, returned. Save that this time I did not walk with my arms bound to my sides.
"Left now—"
"Why? How do you know?"
"Life force in that direction."
I tried mind-probe for myself. She was right—a flicker of energy. It was not the high flow I associated with the aliens, but more like such as I could pick up when not too far from a crew member. And there was an opening to the left.
How far we were from the chamber of the globes now I could not guess. But a lighting of the way cheered us—and that grew ever brighter.
Only now there was sound also. Not a mutter of voices, but rather the clank of metal. Maelen pushed against me.
"He, the one who wears Griss's body—ahead!"
I tried no probe. I wished I could do just the opposite, reduce all mental activity so far down the scale he could not pick up any hint of us in return. I had not forgotten how easily he had found me out when I had spied on the jacks.
"He is one-minded now," Maelen told me, "using all his power for something which is of very great importance to him. We need not fear him, for he puts all to one purpose."
"And that?"
She did not reply at once. Then—
"Lend me of your sending—"
It was my turn to hesitate. To strengthen any mind-seek she might send out could make us more accessible to discovery. Yet I trusted her enough to realize that she would not suggest such a move unless she thought we had a fair chance. So I yielded.
Her probe sped out, and I fed my own energy to it. This we had not often done, so it was a relatively new experience for me, bringing with it an odd sensation of being pulled along in a current I could not fight. Then a blurred mind-picture came.
We seemed to be hanging in the air over a pit, or rather we were in the apex of one of those pyramid chambers. Below a robo was blasting away at the foot of one wall. There was already a dark cavity there; now the machine was enlarging that.
Behind the worker stood Griss. He did not hold any control board. It would appear that he was able to keep the robo at work without that. And his attention was completely absorbed by what he was doing. But that feverish desire which drove him was like a broadcast. He did not hold his defenses now, but fastened avidly on what he sought—an ancient storehouse of his kind, perhaps containing machines or weapons. His need was like a whiff of ozone. A whiff, I say, because I caught only the edge of it. Around the chamber, well above the level at which the robo worked, was another of the ledge ways. This ran across one wall, leading from one door to another. And without needing to be told, I recognized that this was the path we must follow.
Whether we could do it without attracting attention from below was another matter. But now that hole the robo battered was larger. The machine wheeled back, became inert. And the alien hurried to the break, disappeared through it.
"Now!"
We sped along the lighted corridor, and it was only a short distance until we ventured out on that ledge. It was so close to the apex of the pyramid that the opposite wall leaned very close. Maelen found it easier to take that route than I, for I could not stand erect but had to go on hands and knees.
Nor did I waste any time looking back at the hole the robo had opened. To reach the door on the other side, scramble within, was all I wanted.
"We made it!"
"For now, yes," she answered me. "But—"
She swung around, her head down. Her dusty body quivered.
"Krip! Krip, hold me!" It was a cry for help, coming so suddenly, without warning, that I was startled. Then I half threw myself over her, grasping her tightly around the body, holding on in spite of her struggles for freedom.
It was no longer Maelen whom I held so, but an animal that growled and snapped, struck out with unsheathed claws. Only by pure chance did I escape harm. Then she collapsed against me, her breath coming in deep gasps. There were flecks of white foam at the corners of her jaws.
"Maelen, what is it?"
"The calling—it was stronger this time, much stronger. Like—like to like!"
"What do you mean?" I still held her but she was far from fighting now. As if her struggle had exhausted her, she was in nearly the same condition in which I had earlier found her.
