Tron

been dreading, a yell of alarm from one of the distant guards.

Whether their movement had attracted the guard’s attention or a chance sideways glance had permitted him to spot them, they never knew. Tron and Yori dashed to the opposite side of the hallway as more Memory Guards took up the cry and started toward them at a run. The two squeezed through a narrow opening in the wall as Tron silently thanked the Users that he and Yori were familiar with the layout of the Tower as a result of their friendship with Dumont, perhaps more familiar than the Memory Guards.

Tron slid a panel over the opening and secured it; a number of such panels were in this area of the wall. The guards would be delayed in finding the right one, then forcing it. The two were in a utility shaft a hundred yards wide; it stretched upward through the Tower, crowded with coiled, intertwined cables and lines and wires, some of them narrower than Yori’s little finger, some many times thicker than Tron was tall.

Selecting one of the widest cables, Tron started climbing, followed by Yori. The two hauled themselves hand over hand, finding abundant footing, ascending from coil to tangled coil. The climb was demanding, and both were careful not to look down. Yori watched Tron, using the purchases he found. Tron listened constantly for Memory Guards’ voices, for commands to halt. But none came; the pair struggled upward.

After what felt like hours of climbing and straining they reached a ledge high above the corridor level. Tron dragged himself onto it and helped Yori after. They paused, regaining their strength and breath, leaning on one another. Again they embraced, Yori running her hands over his chest.

Tron could bring himself to let her go only by an application of willpower. “Ready?” he asked, with a smile that was an apology. She nodded; they started off along the ledge, past the walls of service instrumentation and circuitry that serviced the Tower. At the end of the ledge a window admitted a strong golden light from the Inner Chamber. They stepped over twisted cables and thick bundles of bound lines, and peered down through the opening.

The Walls of the Inner Chamber, sloping inward toward their base at a 45-degree angle, were smooth and reflective, their incline even more gentle at the bottom. Far below was the main altar, raised above the floor on its circular dais, against one wall. Beyond it lay a darkened passageway. The main altar rested on a secondary one, this one fifty feet square. On the secondary altar was Dumont in his control pod; it was difficult to tell from where they watched, but he appeared to be asleep. The Inner Chamber was filled with a droning chant, a continuous reminder that this was the place in which the Users spoke. Being there again, Tron was unable to understand how any program could deny the existence of those who had created the System. Yori, too, was plainly moved at being within the Input/Output Tower once more.

A sound from the utility shaft interrupted them. They raced back to look down it, and saw a barge rising toward them, carrying guards who were inspecting openings and hiding places at every level, and examining the cables.

Kneeling on the shaft’s rim, Tron watched the craft’s ascent pattern. The very slow, methodical ascent meant that the guards had no idea where their quarry had gone.

“They don’t see us,” Yori breathed. Tron looked up at her. “I’ll go first,” she said, indicating the Inner Chamber.

“All right. I’ll watch that thing.” There might be danger ahead as well as behind, but the plan seemed best for now. Yori drew herself halfway through the window, then paused to give him a mischievous wink. Tron marveled at her courage. He held her arm as she lowered herself gingerly from the window, sliding onto the pitched surface of the wall. He took another look at Durmont, who hadn’t moved, then released Yori’s arm.

She began her long slide to the floor of the Chamber, gathering speed on the sloped wall, thankful that her durable working attire would protect her from friction. Tron, gripping the window ledge, watched her anxiously. Yori steered herself skillfully downward with hands and feet and by leaning her body. Tron returned to the shaft for a quick look, only to find the guards’ barge rising toward him sharply. Somehow, they had spotted him. He heard the shouts of approaching Memory Guards.

Tron turned from the shaft at once and vaulted through the window with less regard for control than Yori had shown, gathering speed quickly. He doubted that the Memory Guards would follow him down the wall, since that would make them vulnerable to his attack at the bottom, and their craft would have to remain in the shaft. But a detachment of guards would be on their way to the Inner Chamber very soon; he had to deal with Dumont before they got through the titanic doorway.

Below, Yori slid to a halt out on the Chamber’s floor, her momentum spent. She looked again to Dumont, whose eyes were closed, then up at Tron, who was swooping down the inclined plane of the wall faster than she had.

Tron skidded to a stop near where she sat and was at her side in an instant, gripping her shoulders. “Are you all right?”

Yori laughed and the big, alluring eyes shone. “That was fun! I should have used that entrance before!”

He looked back to the window. “The guards saw me. Come on!” He helped her to her feet and they ran toward the secondary altar and Dumont.

The Guardian of the Input/Output Tower was ensconced in his control pod; he and it were one. He resembled a sphinx rendered in instrumented, alien style, his circuitry aglow. The bulging headpiece which enclosed his face rose above him like a lofty miter, or the abdomen of some giant insect. He had no visible limbs or torso; he merged directly with the squat control pod.

As Tron and Yori reached the foot of the staircase leading to Dumont’s altar, a hot defensive field began to radiate from it, forcing them to halt. Dumont’s eyelids opened; Tron and Yori saw that he had been aware of their presence all along.

“Halt!” Dumont commanded, his voice aged and stern.

Confused and hurt by the rebuff, not understanding how a friend could act so, Yori exclaimed, “Dumont!”

The Guardian ignored that. “I can’t stand all this commotion!” he complained in an irritated tone. Tron wondered if he meant only their own intrusion or the general furor they’d touched off. “What do you want?” Dumont finished testily.

Tron began tentatively, “I—I have come to communicate with my User.” It would have been such a perfunctory explanation at one time, and now it was a prohibited phrase.

“Hmm,” Dumont considered it. Yori, hearing him, found herself suspecting that Dumont had already made up his mind, and not in their favor. “A difficult proposition; difficult proposition at best.” His eyes swept the emptiness of the Inner Chamber. Their gazes followed his as he told them, “Not so long ago you could’ve come in here and seen programs lined up all the way back to those doors, waiting for communion with their Users.”

He’d meant the doors at the far end of the gigantic corridor, but when he turned that way, Tron noticed that the huge innermost door was now closed, the Memory Guards shut out for the time being. That could only be Dumont’s work. But is it to protect us, or to prevent our escape? he asked himself.

“But now,” Dumont sighed, “this so-called Master Control Program is cutting programs off from their natural creators. Why, I could get myself de-rezzed just for letting you in here.” He raised his eyes to the upper reaches of his province, observing, half to himself, “They hate this Tower. They’d close it down if they dared to. But they keep me around, in case one of them wants to deal with the Other World once in a while.”

He sounded infinitely weary, disillusioned with a System where such things would be permitted. But his voice had held a particular distaste in speaking of them, the MCP and Sark and their servants. Perhaps there was a chance yet.

Tron took a step nearer, feeling the heat of the defensive field. “Dumont, my User has information that could—” He groped for the right words; mention of Sark and the MCP might have the wrong effect. “—could make this a free System again!”

Dumont’s answer was a brief bark of scornful laughter. “Really,” Tron maintained doggedly. “You’ll have programs lined up around the block to use this place, and no MCP looking over your shoulder.” He watched the old Guardian’s face.

Dumont’s voice held less sarcasm, more resignation. “When you’ve been in the System as long as I have, you hear many promises, many reassurances, many brave plans.” There was, though, a note in his voice that spoke of a wavering, a suppressed desire to be convinced.

Yori walked up to the stairway, giving Dumont time to see what she intended, and the defensive field died
