Episode 3: The Descent
The heavy door groaned open, and the tunnel beyond yawned dark and steep, sloping down into the deep heart of the dying world. Sergeant Aldric went first, his lantern held high, with Emil close behind and Tom riding on his shoulder.
"Stay close, and step exactly where I step," Aldric warned, his voice low and steady. "These tunnels were dug during the war, and the war does not forgive carelessness, even thirty years later. My unit lost good people on this very path. Watch everything. Touch nothing without my word."
Down they went, deeper and deeper, the air growing colder and closer around them. The tunnel was old and rotting — its timber supports furred with mold, its steel beams weeping rust, the walls glistening with damp. Every few steps, the lantern light fell upon some grim relic of the war: a rusted weapon, a fallen helmet, the scratched initials of long-dead soldiers carved into the timber. It was a tomb, this tunnel — and they were walking down its throat.
They had not gone far when Aldric suddenly threw out his arm, halting them in their tracks. "Stop." His voice was sharp. "Do not move. Either of you."
Emil froze, his heart hammering. "What is it?"

Aldric pointed, and Emil followed his gaze — and there, stretched across the tunnel at ankle height, almost invisible in the gloom, was a thin, taut wire.
"A tripwire," Aldric said grimly. "One of ours. Step on it, and the whole ceiling comes down on top of you." He knelt slowly, studying it, then traced its line to a rusted mechanism in the wall. "The traps are everywhere down here. We laid them ourselves, to slow the enemy if they ever broke through. I know most of them — but thirty years is a long time, and some I may have forgotten, and others may have shifted." He carefully wedged the trigger with a sliver of metal, disarming it. "We step over this one. High. Slowly. I'll go first."
One by one they stepped carefully over the deadly wire, and Emil's heart did not slow until they were all safely past. "How many more like that?" he asked.
"Many," said Aldric simply. "This is why I could never make the journey alone. A single man, even a careful one, makes mistakes — and down here, one mistake is all it takes. But three sets of eyes... three sets of eyes might just make it." He almost smiled. "I have waited thirty-one years for three sets of eyes."

On they went, and the journey tested them at every turn. They came to places where the tunnel had been deliberately defended — old security checkpoints, sealed with heavy blast doors that would not open without solving the puzzles built to guard them. At one such door, they found a great rusted dial set into the steel, and a riddle scratched into the wall above it in the old soldiers' code. Aldric remembered the war-time ciphers, and Emil was clever with patterns, and Tom — small enough to slip into the mechanism and check the gears — found the catch. Together, the three of them puzzled it out, turned the dial to the proper sequence, and the great door ground slowly open. Apart, none of them could have done it. Together, they could.
"You see?" Aldric murmured, as they passed through. "These tunnels were built to stop one person, or two, or a whole army. But they were never built to stop friends working as one. That is a thing the war-makers never understood. They built everything to divide. They never reckoned on people who would help each other."
But the deeper they went, the more dangerous it became. They were perhaps halfway down — the soldier's old map showed them passing the midpoint of the descent — when disaster nearly struck. They were crossing a long, low gallery, its timbers rotted and groaning, when the ground gave a deep, sickening shudder.
"Move!" Aldric bellowed. "The roof — it's coming down — RUN!"

They ran. Behind them, with a roar like thunder, the ceiling of the gallery collapsed, a great avalanche of rock and rotten timber crashing down where they had stood a heartbeat before. Emil scooped Tom up and dove forward, dust billowing all around, stones smashing down at their heels — and Aldric, with surprising strength for so old a man, seized them both by the collar and hauled them clear, the three of them tumbling together onto solid ground as the gallery sealed itself shut behind them in a cloud of choking dust.
For a long moment they lay there, coughing, hearts pounding. Then Tom wheezed, "Is — is everyone all right?"
"We're all right," Emil gasped, sitting up. "Sergeant — thank you. You pulled us clear."
"We pulled each other clear," Aldric corrected, getting slowly to his feet and dusting himself off. He looked back at the collapsed gallery — now an impassable wall of rubble. "There's no going back that way now. The only path left is forward, and down." He picked up his lantern, which had miraculously survived, and relit it. "Come. We've no choice but to press on."
They pressed on. And after a while, the character of the tunnels began to change. The timber and rusted steel of Aldric's own side gave way to something different — darker, harder, more brutal. The walls were scarred with old blast-marks. The relics they passed were not from Aldric's army, but from the enemy's — strange, angular helmets, unfamiliar weapons, signs in a script Aldric read with a grim and bitter face.

"We've crossed over," he said quietly. "These are the enemy's tunnels now. In the war, they broke through here — fought their way deep underground, and held this whole section against us, for years. The fighting down here was..." He paused, his face shadowed. "It was the worst of the whole war. The very worst. And when they finally fell back, they left their tunnels defended — automated, so they would not have to die holding them." He raised his lantern, and ahead, in the deep darkness, a faint, sinister red glow pulsed slowly — the glow of old enemy machines, still keeping their watch after thirty years.
Emil peered into the red-lit gloom. The enemy's old tunnels stretched away before them — a wrecked underground battlefield of shattered trenches, broken war-machines, and the dim, pulsing red eyes of automated defenses that had never been told the war was over.
"They're still active," Aldric murmured. "After all these years. Sentry-guns. Automated defenses. They don't know the war ended. They don't know there's nothing left to defend. They'll fire on anything that moves — friend or foe, soldier or child. They cannot tell the difference. They cannot be reasoned with. They simply... kill, because that is all they were ever built to do." He turned to Emil and Tom, his face grave. "This is the most dangerous part of the whole journey. To reach the bomb, we must cross the enemy's dead ground — right through the heart of their old defenses, with those guns still watching." He took a slow breath. "But there's hope. Somewhere just ahead, on the edge of the contested zone, there was an old command post — a fortified room where supplies were stored. If it survived, we can rest there, and resupply, and find what we need to get through what lies beyond." He looked at the pulsing red glow. "If it survived. And if we can reach it before the guns find us."
Emil looked at the red-lit ruin ahead — the dead, mechanical heart of the worst fighting of the war — and felt a cold dread settle in his stomach. But he looked, too, at the old soldier beside him, who had carried this burden alone for thirty-one years, and who needed them now more than anyone had ever needed them.

"Then let's reach that command post," Emil said quietly, helping Tom up onto his shoulder. "Together. One careful step at a time."
And the three of them crept forward, out of the rubble and into the red-lit dark of the enemy's dead ground — where the machines of a forgotten war still watched, and waited, in the silence.
