C10 Chapter 10: Poisoned Tunnels

The floorboard creaked again.

Kael pressed Jen against the wall, his hand still over her mouth. Milo sat frozen on his bunk. Cora's mage-light had gone out, plunging the room into darkness. Outside the door, Thorne's breathing was slow and steady, close enough that Kael could hear the rustle of his robes against the wood.

"Miller." Thorne's voice was soft, almost pleasant. "I know you're in there. You and your little friends." A pause. "I'm not going to hurt you. I just want to talk about what you took from me."

Kael's fingers tightened around his knife. The letter was still in his tunic, the wax seal pressing against his skin like a brand.

"Open the door, Miller. We can resolve this quietly. No one else needs to get involved."

Jen pulled Kael's hand off her mouth. Her lips moved soundlessly: Back window.

Kael nodded. He pointed at Milo, then at the window. Milo slid off his bunk, his bare feet silent on the cold stone. Cora was already moving, her book clutched to her chest, her dark eyes fixed on the door.

"Miller?" Thorne's voice hardened. "I'm losing patience."

Kael moved. Not toward the door—toward the window. He grabbed the frame and hauled himself through, dropping to the grass below. Jen landed beside him. Then Milo, his heavy frame somehow silent. Cora last, her bare feet barely touching the ground.

They ran.

Behind them, the dorm door splintered. Thorne's roar echoed through the night. "MILLER!"

Kael didn't look back. He led them through the dark, past the library, past the training yards, until they reached the broken wall at the edge of campus. They ducked through a gap in the stones and crouched in the shadow of the outer palisade.

"We can't go back." Jen's voice was sharp, breathless. "He'll kill us."

"He'll kill everyone." Kael pulled out the letter. The black wax seal glinted in the faint starlight. "The water supply. He's going to poison it tonight. The whole academy."

"Then we stop him." Everyone turned. Cora had spoken. Her voice was soft, barely a whisper, but her eyes were hard. "The waterworks are under the main hall. If we can get there before him—"

"We can't fight an Adept." Milo's knuckles were white on his axe. "We're Initiates. He'll tear us apart."

"We don't need to fight him." Kael's mind was racing. "We need to catch him in the act. With witnesses. Someone with authority who can arrest him on the spot."

"Elara." Jen nodded slowly. "She's the only instructor who's been asking questions. The only one who doesn't seem to be in Thorne's pocket."

"Then we split up." Kael tucked the letter back into his tunic. "Jen, you set a fire in the west training yard. Big enough to pull the guards away from the main hall. Milo, you go with her. Cora, you find Elara. Tell her everything. Bring her to the waterworks."

"And you?"

Kael's hand went to his knife. "I'll be inside. Waiting for Thorne."

The waterworks were cold and dark, carved into the stone beneath the main hall. A single massive reservoir dominated the center, thirty feet across, its surface still and black. Pipes branched off in every direction, feeding water to the dorms, the dining hall, the bathhouses. One dose of poison here would spread to every corner of the academy within hours.

Kael crouched behind a stack of wooden crates near the back wall. His heart was a war drum against his ribs. His palms were slick with sweat. The crystal in his chest hummed, pushing the bear's rage and the fox's stealth and the rabbit's speed through his veins all at once, demanding action.

He'd been waiting for twenty minutes.

Outside, a faint orange glow flickered through the high windows. Jen's fire. Shouts echoed across the campus—guards scrambling toward the training yard, boots pounding on stone. Kael tracked the sounds with his enhanced hearing, picking out Jen's voice cutting through the chaos, sharp and urgent.

She's better at this than me, he thought.

The basement door creaked open.

Kael pressed himself deeper into the shadows. Footsteps on the stone stairs—slow, deliberate. The hem of a black robe dragging across the floor.

Thorne stepped into the dim light. His face was drawn and tight, his gray eyes darting around the chamber. In one hand, he held the glass vial. In the other, his purple-glowing sword.

"Miller." His voice echoed off the stone walls. "I know you're here. Your little fire was clever. I'll give you that. But it won't save you."

Kael didn't move. His enhanced hearing tracked Thorne's heartbeat—elevated, anxious. He was scared. The stolen letter had rattled him. He knew his plan was unraveling.

Thorne walked to the reservoir's edge. He uncorked the vial and held it over the dark water.

"Once this is done," he muttered, "the Sect won't care about one missing letter. They'll have everything they want."

Kael stepped out of the shadows. Knife drawn.

"Don't."

Thorne froze. He turned slowly, and when his eyes found Kael, a slow, cold smile spread across his face.

"There you are."

"You don't have to do this." Kael's voice came out steadier than he felt. "Elara's on her way. The guards will be here any minute. It's over."

Thorne laughed. It was an ugly sound, echoing off the stone. "You think Elara can save you? By the time she arrives, you'll be dead, the poison will be in the water, and I'll be gone. The Sect will burn this academy to ash, and no one will ever know I was here." He raised the vial. "Goodbye, Miller. Or should I say—Ryn?"

He tipped the vial.

Kael moved.

The rabbit's burst speed launched him across the chamber. He slammed into Thorne's arm, knocking the vial out of his hand. It shattered on the stone floor, clear liquid hissing as it ate into the rock.

Thorne's sword came up. Purple light slashed through the air. Kael ducked—too slow. The blade caught his shoulder, burning through cloth and skin. He screamed, the pain white-hot, and stumbled back.

"Did you think this would be easy?" Thorne advanced, his sword glowing brighter. "I've been hunting your family for years, boy. Your father thought he could outsmart us. Your mother thought she could hide you. They were wrong."

Kael's shoulder blazed. His knife was still in his hand, but the blade felt tiny against Thorne's sword. The bear's rage roared in his chest—fight, crush, kill—but he forced it down. Rage wouldn't win this fight. Tactics would.

He triggered the fox's stealth and slipped sideways into the shadows. Thorne's eyes tracked him, confused, and Kael used the heartbeat of disorientation to scramble up onto a stack of crates.

"Come out, coward!" Thorne's sword slashed through the darkness, carving splinters from the wood.

Kael dropped onto him from above.

His knife drove into Thorne's shoulder—not deep enough to kill, but deep enough to make the instructor scream. Thorne's sword clattered to the stone. Kael grabbed it and hurled it into the reservoir. It sank beneath the black water with a hiss.

"You little—" Thorne's fist caught Kael in the ribs. Something cracked. Kael flew backward, slamming into a crate, wood splintering around him. His vision blurred. Blood filled his mouth.

Thorne advanced, one hand pressed to his bleeding shoulder, his face twisted with fury. "I'm going to enjoy this."

He raised his hand. Purple energy gathered at his fingertips—a bolt of Void energy, crackling and hungry.

Then the basement door exploded inward.

Elara stood in the doorway, sword drawn, her silver hair wild in the torchlight. Her gray eyes swept the chamber—Kael bleeding against the crates, Thorne with his hand raised, the shattered vial on the floor—and her expression went hard as iron.

"Thorne." Her voice cut through the chamber like a blade. "Step away from him. Now."

Thorne spun, his face cycling through shock, calculation, and finally desperate fury. "Elara. Thank the heavens you're here. This boy—this Miller boy—he broke in. He was trying to poison the reservoir. I caught him in the act—"

"I heard everything." Elara stepped into the room, her sword still raised. "The poison. The Shadow Sect. The invasion plan. You're a traitor, Thorne. Surrender now, or I'll execute you where you stand."

For a long moment, no one moved. Thorne's eyes darted between Kael and Elara, the purple energy still crackling at his fingertips.

Then he lunged.

Not at Elara—at Kael.

The bolt of Void energy screamed across the chamber. Kael threw himself sideways, the rabbit's speed saving him by inches. The bolt hit the stone wall and exploded, shards of rock raining down.

Elara moved faster than Kael could track. One moment she was at the door. The next, her sword was at Thorne's throat, her knee in his back, his arm twisted behind him at an angle arms weren't meant to bend.

"The headmaster will want to speak with you," she said, her voice cold. "You can tell him everything about the Sect's plans. Or you can die here. Your choice."

Thorne went limp. Defeated.

Kael slumped against the crates. Every breath hurt. His shoulder was still bleeding, the wound burning with residual Void energy. But he was alive.

Cora appeared in the doorway, her book still clutched to her chest. Behind her, Jen and Milo, their faces streaked with soot from the fire.

"Got him," Jen said. "You actually got him."

Kael tried to stand. His legs wouldn't hold him. Elara's hand caught his arm, steadying him.

"Easy, Miller." Her gray eyes studied his face. "You're bleeding. And you've got some explaining to do."

"Later." Kael's voice was hoarse. "First, there's something you need to know."

He pulled the letter from his tunic. The black wax seal was cracked, but the skull crest was still visible. He pressed it into Elara's hand.

"The invasion is in four weeks. There are more Sect spies inside the academy. And the water—" He coughed, blood spattering his lips. "The vial broke before he could empty it. But some of the toxin might have gotten into the reservoir. You need to test the water. Warn people before anyone drinks it."

Elara unfolded the letter, her eyes scanning the coded text. Her jaw tightened.

Then Thorne, pinned on the ground with Elara's knee in his back, started to laugh.

"You think this is over?" His voice was thick with pain, but his eyes were bright, feverish. "You think catching me changes anything? The toxin is already in the pipes. By morning, half the students will be coughing up blood. And when the Sect arrives—" He grinned, blood staining his teeth. "They'll finish what I started."

Elara hauled him to his feet. "Guards! Take him to the dungeon. No visitors. No correspondence."

Guards poured into the chamber. Thorne was dragged away, still laughing, his voice echoing off the stone walls until it faded into silence.

Kael stood in the wreckage of the waterworks, bleeding and exhausted, and watched him go. The letter was in Elara's hand. The poison was in the water. And somewhere out there, the Shadow Sect was preparing to attack.

They'd won tonight. But the war was just beginning.
