Rowan and Aldren moved quickly toward the northern district. The sun had risen fully, but the light struggled against a thin haze of drifting mana. The storm from yesterday had left residue, faint enough to ignore but strong enough for someone with malicious intent to exploit.

They reached a maintenance stairway leading underground. Rowan descended first, holding a lantern whose gentle glow revealed cracks along the walls. Not structural cracks—mana cracks. The kind that formed when resonance channels were stressed repeatedly.

Aldren followed silently, every sense alert. The underground path branched into three tunnels. Rowan consulted his leyline map and pointed to the central one.

“This tunnel runs directly above a minor convergence. If the rogue faction manipulates it, they could force a ripple that destabilizes the northern towers.”

Aldren nodded. “Then that’s where they’ll be.”

The tunnel twisted downward. The air grew heavier. The mana glow strengthened, pulsating faintly between stones. Rowan placed a tuning rod into a gap in the wall. The rod vibrated rapidly.

“Unstable flow,” Rowan muttered. “They’ve already been here.”

They pressed deeper.

At the end of the tunnel they found a small chamber. Old support beams framed the space. Dust and discarded rune fragments littered the floor. Rowan knelt to examine the debris. Every rune piece showed deliberate breakage.

Aldren frowned. “What does breaking runes do?”

“Break the wrong rune,” Rowan said, “and you weaken the boundary keeping leyline pressure stable.”

Aldren exhaled sharply. “So they’re pulling bricks out of the city’s foundation.”

Rowan nodded grimly.

He leaned closer to the wall and discovered three fresh runes carved into the stone. Not old. New. Sharply edged. He recognized them immediately.

Mana pulse accelerators.

If activated during another storm, these runes could magnify minor fluctuations into violent bursts. Three such runes inside a channel could trigger a cascading effect.

He felt his pulse quicken.

“They’re trying to weaponize the northern channel.”

Aldren stepped toward the runes. “Can you disable them?”

Rowan nodded. “But I have to be careful. If I carve wrong, the channel will react.”

Rowan retrieved his precision chisel and a stabilizing charm. He placed the charm next to the first rune. The charm glowed faint blue. Rowan traced a counter symbol around the rune.

A faint crackle filled the air. The light dimmed. The rune dissolved.

“One down,” Rowan whispered.

He moved to the second rune. As he began carving, the chamber trembled. Aldren stepped protectively in front of Rowan. Dust drifted down from the ceiling.

“Someone is watching,” Rowan whispered.

Aldren drew his sword. “Where?”

Rowan did not answer. He continued carving. The rune resisted, flickering with red mana.

A voice echoed from the shadows behind one of the beams.

“You take stones away faster than we place them.”

Rowan recognized the distorted tone. A rogue mage.

Aldren moved between Rowan and the voice. The rogue mage stepped from the shadows, cloak rippling like liquid smoke. His eyes burned with unhinged fervor.

Rowan kept carving, refusing to stop.

The rogue mage raised a hand, conjuring a chaotic swirl of mana.

Aldren lunged. The mage dodged, casting a wave of unstable force. The blow hit a support beam, sending debris flying. Rowan shielded his head but kept the chisel steady, carving the final stroke.

The second rune shattered.

The rogue mage shrieked with rage.

“You silence the city’s voice!”

Rowan rose slowly. “I’m preventing it from screaming.”

The mage cast another burst of unstable mana. Aldren blocked it with his shield. The force sent him sliding back but he held firm.

Rowan stepped toward the mage. “You think chaos is freedom. But chaos is collapse. It kills more than it liberates.”

The mage hissed. “Collapse destroys the old world, so a new one can rise!”

Rowan shook his head. “Cities aren’t reborn through ruin. They grow through guidance.”

The mage lunged forward, mana swirling wildly. Rowan stepped aside. Aldren struck with his shield, knocking the mage back. The rogue stumbled, losing balance. As he tried to cast again, the unstable mana backfired, sending him crashing into the chamber wall.

The mage collapsed, cloak still smoking.

Aldren exhaled. “Is he—?”

“Alive,” Rowan said. “Barely. But his runes were the real danger.”

He approached the third rune. It glowed with deep red intensity.

“This one is connected to something above,” Rowan murmured. “If I break it, I trigger backlash.”

Aldren stepped closer. “So what do we do?”

Rowan placed both palms on the rune and whispered. “We redirect.”

He traced a spiral around the rune and then carved a grounding mark beneath it. Mana surged up his arm, stinging. He grit his teeth and pushed. The red glow flickered faded and vanished.

Silence fell.

Rowan staggered forward. Aldren caught him.

“You alright?”

Rowan nodded weakly. “The channel is stable now. But this was only one chamber. They may have more.”

Aldren sighed. “Then we’ll find them.”

They bound the unconscious rogue mage and flagged guards to escort him to the palace for interrogation.

As Rowan stepped out of the tunnel the air felt slightly lighter. Stable. He took a deep breath.

“We have time,” he said softly. “Not much. But enough.”

Aldren smiled faintly. “And that’s all you need.”

Rowan nodded. “Let’s return to the Hall. We need to reinforce the northern towers next.”

As they walked back toward daylight Rowan whispered under his breath.

“The city won’t fall. Not while I still breathe.”
