Monster Contract: My Pets Will Bring the Apocalypse

Ride of the Devourer

Fenrir kept staring, waiting for an answer that wasn't coming. Seojin shifted where he knelt, still catching his breath, and finally shook his head.

"I'm not anything special. I'm just human. I don't know who Odin is, and I don't know why your power answers to me. I didn't even know I had any power until a minute ago."

Fenrir studied him a moment longer, those black eyes searching for a lie that wasn't there. Whatever he found, or didn't find, seemed to settle something in him, because the tension in his shoulders eased and he let out a low breath through his nose.

"Human," he repeated, like the word tasted strange in his mouth. "Then you truly do not know. Very well. I will not waste breath explaining what a mortal mind was never built to hold."

He rose to his full height, chains still dragging loose from his legs, and turned his head slowly to take in the chamber around them.

"Tell me where we are, at least. What realm is this?"

"We're in a dungeon," Seojin said, pushing himself up off the floor.

Fenrir's ears flattened. "A what?"

"A dungeon. It's what we call places like this. Rifts open up and drop pieces of other worlds into ours, and this is one of them."

"That means nothing to me."

Seojin rubbed the back of his neck, trying to think of a simpler way to say it. "Okay. We're on Earth. That's the name of this world."

Something shifted behind Fenrir's eyes, recognition slow and heavy. "Midgard," he said, more to himself than to Seojin. "So that is where his trickery sent me. Fitting, in its own cruel way."

He didn't explain further, and Seojin didn't ask. There was too much weight behind the word for it to be a simple answer, and he had a feeling that pulling on that thread would take longer than either of them had right now.

Fenrir turned toward the far wall, muscles coiling beneath his fur, and without warning he lunged. His shoulder slammed into the stone hard enough that the whole chamber shook and dust rained down from the ceiling. The wall didn't crack. It didn't even shudder. Fenrir bared his teeth and hit it again, claws raking deep gouges into the obsidian veined rock, but the stone held firm like it had been built to hold something far stronger than him.

"This cage remembers its purpose," Fenrir growled, pacing back with his hackles raised.

Before Seojin could answer, the air in front of them flickered and a pale blue screen bloomed into view.

[Quest Update] [Dungeon Objective Unlocked: Defeat the Boss of the Rift] [Completion Required for Exit]

Seojin read it twice, then looked up at Fenrir. "That's how we get out. There's something in here we have to kill first. A boss. Whatever's guarding this place, we beat it, and the exit opens."

Fenrir's lips peeled back from his teeth in something that wasn't quite a smile. "Then let us go greet our host."

"Wait, how do we even find it, we don't have a map or anything, we don't know where—"

Fenrir was already moving. He dropped low and Seojin barely had time to grab a fistful of fur and swing himself up before the wolf exploded forward, claws tearing furrows into the stone floor with every stride. They hit the far wall at full speed and it gave way this time, shattering into rubble under the force of a body that size, and Seojin realized the wall hadn't been holding Fenrir in. It had only been keeping him from leaving until the quest allowed it.

They tore through corridor after corridor, the tunnels narrow at first and then widening into caverns strung with glowing fungus and threaded roots. Fenrir didn't slow down for any of it. Twice something skittered out of the dark to intercept them, some clawed thing with too many joints, and both times Fenrir barely broke stride, a single snap of his jaws or a swipe of one massive paw enough to send the creature flying off into the shadows behind them.

Seojin held on with both hands, wind tearing at his hoodie, his whole body thrumming with something he didn't have a name for. Every time Fenrir moved, he felt it too, a rush of heat under his skin, a sharpness in his senses that hadn't been there an hour ago. It should have terrified him more than it did.

The tunnel opened without warning into a cavern so vast the ceiling disappeared into darkness above them. The air here was different, thick and metallic, charged like the moment before lightning strikes. Massive iron chains hung from the walls in loose coils, rusted and ancient, and at the center of the cavern floor, a shape began to move.

It rose slowly, plates of black iron grinding against each other as it unfolded to its full height, easily twice as tall as Fenrir. Its body was built from the same chain and iron that had bound Fenrir in the first place, forged into something with the rough shape of a hound but wrong in every proportion, too many joints in its legs, a skull too long and studded with dull iron teeth. Where its eyes should have been, there were only two cold blue runes, burning faint and steady.

"A Warden," Fenrir said, and for the first time since Seojin had met him, there was something almost like caution in his voice. "Built from the same chains that held me. Something forged with one purpose. To hunt down what escapes."

The Warden's runes flared brighter, and chains began to unspool from its shoulders and back, each one lifting into the air like a living thing, its ends sharpened into hooks and blades.

"It knows you," Seojin said, throat tight.

"It was made to know me." Fenrir's whole body dropped low, muscles coiling. "Hold on, boy. This will not be gentle."

The Warden struck first. A dozen chains lashed out at once from every angle, faster than something that size had any right to move, and Fenrir twisted beneath Seojin with a speed that nearly threw him off. Two chains slammed into the ground where they'd been standing a heartbeat before, cratering the stone.

Fenrir answered by driving forward, claws digging deep gouges into the cavern floor as he closed the distance in three bounding strides. The Warden swung one massive iron limb down like a hammer, and Fenrir ducked beneath it, jaws snapping shut around one of its front legs. Metal shrieked. Sparks scattered across the stone. But the leg didn't tear free the way flesh would have, and the Warden used the opening to slam its skull down toward them.

Seojin threw himself flat against Fenrir's back as the iron jaws snapped shut inches from his head. Fenrir released his grip and spun away, putting distance between them, chest heaving, a thin line of black blood welling where one of the Warden's teeth had grazed his shoulder.

"It's built to counter you," Seojin said, gripping tighter. "It's not going to fight fair."

"Good," Fenrir said. "Neither will I."

The chains came again, faster this time, weaving through the air in a pattern meant to box them in from every side. Fenrir didn't try to dodge them all. He let two catch against his flank, teeth gritted as the hooks bit in, and used the anchor of them to swing his whole body around and slam into the Warden's side with the force of a falling mountain. The impact staggered the construct, chain links groaning under the strain, and for the first time it took a step back.

Fenrir didn't let up. He tore free of the chains still hooked into his side, ripping skin and taking iron with it, and lunged again before the Warden could reset its stance. Claws raked across the construct's chest, peeling away plates of ancient iron, and beneath them Seojin caught a glimpse of something glowing, a core of pale light buried deep inside the thing.

"There," Seojin shouted, pointing. "That's what's keeping it moving. I can feel it."

Fenrir's eyes flicked toward it, and something in his expression sharpened. The Warden seemed to understand the danger too, because it reeled back and slammed both front limbs into the ground, sending a shockwave rippling out through the stone floor. The force threw Fenrir off balance for just a moment, just long enough for the Warden to wrap three chains around one of his hind legs and yank hard enough to drag him off his feet.

Seojin felt the world tilt violently as Fenrir crashed onto his side, and he barely kept his grip on the wolf's fur as they skidded across the cavern floor. The Warden loomed over them, chains coiling back for a killing blow, runes blazing white hot.

Fenrir's chest heaved once, twice, and then he opened his jaws wide and let out a sound that wasn't a roar so much as a force, something ancient rolling up from somewhere far deeper than his lungs. The air itself seemed to bend around it. The chains holding him down snapped like thread, and the Warden staggered back a full step, its iron frame groaning under a pressure that had nothing to do with claws or teeth.

"Let the Nine Realms remember," Fenrir snarled, rising, "that even chains forged to hold me will break twice before they hold once."

He moved before Seojin could even process the words. One instant Fenrir was crouched low on the cavern floor, and the next he was already airborne, closing the gap between himself and the Warden in a single bound too fast to track. His jaws closed around the exposed core in the construct's chest, and he bit down with everything he had left.

The Warden's runes flickered, dimmed, and finally guttered out. Its massive frame swayed once, twice, and then collapsed inward on itself, iron plates crashing to the stone floor in a heap of broken chain and dead metal, dust rising in a slow gray cloud.

Silence settled over the cavern.

Fenrir stood over the wreckage, sides heaving, blood matting the fur along his shoulder and flank. Seojin slid down from his back on shaky legs, staring at the ruin of the Warden, unable to fully believe either of them was still standing.

The system chimed softly.

[Dungeon Boss Defeated.]

[Exit Sequence Initiated.]

[Reward Calculated Based on Performance and Contract Status.]

[Quest Completed]

[Unlocked: Skill Tree]

[Unlocked: Enhanced Strength (Lv1), Enhanced Speed (Lv1), Increased Durability (Lv1)]

Seojin felt his Core pulse against his chest, warm and steady, and something inside him settled into place as it had always belonged there.

He looked over at Fenrir, who had lowered his head, breathing slowly and deliberately, the way someone breathes after running further than they meant to.

"You good?" Seojin asked quietly.

Fenrir didn't answer right away. When he finally spoke, his voice had dropped, softer than anything Seojin had heard from him yet.

"I am. Just catching my breath."

Then his head lifted, eyes bright again despite the exhaustion in every line of his body.

"Hold on tight."

The cavern floor began to tremble beneath them, cracks spreading outward from where the Warden had fallen, and somewhere above the ceiling groaned like it was finally ready to come down.
