He waited until all three men had nodded in agreement, then checked the charge on his gun. Fully loaded. It would be foolish not to go in armed. But he had to. One gun wouldn't save him. He put it aside. The button radio on his collar was working and had a strong enough signal to get through any number of walls. He took off his coat, threw open the door and stepped out into the searing brilliance of the Disan noon.

There was only the desert silence, broken by the steady throb of the car's motor behind him. Stretching away to the horizon in every direction were the eternal deserts of sand. The keep stood nearby, solitary, a massive pile of black rocks. Brion plodded closer, watching for any motion from the walls. Nothing stirred. The high-walled, irregularly shaped construction sat in a ponderous silence. Brion was sweating now, only partially from the heat.

He circled the thing, looking for a gate. There wasn't one at ground level. A slanting cleft in the stone could be climbed easily, but it seemed incredible that this might be the only entrance. A complete circuit proved that it was. Brion looked unhappily at the slanting and broken ramp, then cupped his hands and shouted loudly.

"I'm coming up. Your radio doesn't work any more. I'm bringing the message from Nyjord that you have been waiting to hear." A slight bending of the truth without fracturing it. There was no answer. Just the hiss of wind-blown sand against the rock and the mutter of the car in the background. He started to climb.

The rock underfoot was crumbling and he had to watch where he put his feet. At the same time he fought a constant impulse to look up, watching for anything falling from above. Nothing happened. When he reached the top of the wall he was breathing hard, sweat moistened his body. There was still no one in sight. He stood on an unevenly shaped wall that appeared to circle the building. Instead of a courtyard inside it, the wall was the outer face of the structure, the domed roof rising from it. At varying intervals dark openings gave access to the interior. When Brion looked down the sandcar was just a dun-colored bump in the desert, already far behind him.

Stooping, he went through the nearest door. There was still no one in sight. The room inside was something out of a madman's funhouse. It was higher than it was wide, irregular, and more like a hallway than a room. At one end it merged into an incline that became a stairwell. The other ended in a hole that vanished in darkness below. Light of sorts filtered in through slots and holes drilled into the thick stone wall. Everything was built of the same crumble-textured but strong rock. Brion took the stairs. After a number of blind passages and wrong turns he saw a stronger light ahead. There was food, metal, even artifacts of the unusual Disan design in the different rooms he passed through. Yet no people. The light ahead grew stronger as he approached, the passageway opening and swelling out until it met the larger central chamber.

This was the heart of the strange structure. All the rooms, passageways and halls existed just to give form to this gigantic hall. The walls rose sharply, the room circular in cross section and growing narrower towards the top. It was a truncated cone since there was no ceiling; a hot blue disk of sky cast light on the floor below.

On the floor stood a knot of men staring at Brion.

Out of the corner of his eyes, and with the very periphery of his consciousness, he was aware of the rest of the room. Barrels, stores, machinery, a radio transceiver, various bundles and heaps that made no sense at first glance. There was no time to look closer. Every fraction of his attention was focused on the muffled and hooded men.

He had found the enemy.
