The march back to the Castle of Shadows felt less like a victorious return and more like a punishment for a crime Aris didn't remember committing.
Aris walked at the front, clutching his battered leather satchel against his chest. He felt less like a Demon King and more like a tired university student leading a field trip for freshmen who specialized in "Explosions" and "Complaining."
To his left scuttled King Pinch, the twelve-legged High Geometer. The giant crab was hyperventilating. Every time they passed a tree that wasn't perfectly straight, he would let out a pained click.
"That oak tree," Pinch shuddered, his mental voice vibrating in Aris's skull. "It leans. It has no discipline. Why does nature refuse the Grid?"
"It is seeking the Sun-Mana, Pinch," Aris sighed, translating 'photosynthesis' into terms the crab would accept. "It's efficient energy collection. Nature is just... messy math."
"It is Chaos," Pinch corrected. "I wish to prune it. With extreme prejudice."
To his right walked Krakka, the Goblin Warlord. Krakka was currently trying to chew on a piece of raw quartz because it "looked like rock-candy."
"Boss," Krakka garbled, spitting out gravel. "The walking dinner-plates are boring. I told Shell-Face the joke about the Frost-Bear and the Ice Pit."
"And?" Aris asked, dreading the answer.
"And he asked me for the thickness of the ice!" Krakka threw his hands up. "He has no soul! He is empty inside, like a drum! I want to hit him to see if he booms!"
"Do not strike my carapace," Pinch clicked without looking over. "My shell is hardened by the Salts of the Deep. You would only break your wrist, soft one."
Behind them, the Legends were helping in the worst ways possible.
Valerius, the Pale Saint, was floating dangerously close to the Crab King. She wasn't healing anyone; she was measuring Pinch's legs with a piece of enchanted string.
"The construction is fascinating," Valerius whispered, her eyes wide with a creepy, innocent wonder. "Your joints... they are a miracle of bone-craft. If I removed just one, do you think the marrow would regenerate? Or could I sew it onto a goblin? Imagine... a goblin with scissor-hands. He could trim the hedges. He could be... beautiful."
"Sovereign Aris!" Pinch shrieked, scuttling faster. "Your witch is shopping for my limbs! She looks at me like I am a bag of spare parts!"
"Valerius, stop trying to harvest the workforce," Aris rubbed his temples. "We are not making Scissor-Goblins today."
"Tomorrow then," Valerius noted, scribbling in her black journal. "Tuesday is good for grafting."
Overhead, Garrick was floating on his back, drifting along the air currents like a lazy cloud. He popped a mint-leaf into his mouth.
"You know," Garrick drawled, looking down at the mismatched army. "This is a weird parade. We have a Demon King looking like a stressed scholar, a Hero with a stolen parasol, and an army of walking shield-walls. If we had a bard, this would be a tragic comedy."
"It's not a parade," Aris grumbled. "It's a sanitation convoy."
Elowen, the Mage of Calamity, was skipping alongside the crab ranks, juggling three balls of blue fire. She noticed a Crab drone hesitating before a mud puddle.
"Do you want me to boil it?" she asked brightly, the fire flaring up.
"Negative," the drone clicked. "I am calculating the slip-risk of the terrain."
"Boring!" Elowen giggled. "You calculate, I incinerate! That's the Law of Fire! Did you know that if you heat a crab shell with Spirit-Fire, it turns into a lovely pink dust? It's very good for potions!"
The drone froze, curling into a protective ball. "She is threatening my essence!"
"Elowen," Kaelen's voice drifted back, warm and effortlessly commanding. "Don't cook the builders, please. We need them raw and angry."
"Okay, Big Brother!" Elowen chirped, extinguishing the fire instantly. "I was just motivating them with the threat of death!"
As the castle came into view, the group stopped. The "Sun-Box" Keep—freshly painted neon yellow—glowed violently against the grey sky.
King Pinch's monocle fogged up instantly.
"It... it vibrates," Pinch gasped, clutching his chest-plate. "The main tower... it leans the width of a thumb to the west. Why does it lean? Is the stone drunk?"
"We call that 'The Builder's Curse'," Kaelen noted helpfully, twirling his parasol. "Or 'Good Enough for Government Work'."
They crossed the drawbridge into the courtyard, and the real war began.
The Night Shift Goblins—the ones who had stayed behind—were gathered around a massive pile of scrap metal. They were wrapping a rusted pipe with layers upon layers of a sticky, silver fabric.
When they saw the army of pristine, white crabs marching in, they dropped their wrenches.
"INTRUDERS!" the Night Shift leader, Scrap-Chewer, screamed. "ATTACK THE WALKING PLATES!"
"NO!" Krakka roared, stepping forward. "STOP! They are... allies."
"Allies?" Scrap-Chewer blinked, lowering a rusty spoon he was using as a dagger. "But they look... clean. They smell like math."
King Pinch scuttled forward. He raised a massive claw and pointed it at the pipe Scrap-Chewer was holding.
"Abomination," Pinch hissed. "That pipe has a crooked bend! It is a crime against the Grid! The Water Spirit does not want to twist; it wants to flow!"
"Water goes where we tell it to go!" Scrap-Chewer roared, puffing out his chest. "We use Spin-Logic! If water spin fast, it forgets the earth pulls it down!"
"The Earth always pulls!" Pinch shouted back. "Gravity is the Ancient Law! You are insulting the Earth with your sticky silver rags!"
"It is not rags!" Scrap-Chewer screamed, holding up the roll of silver tape like a holy relic. "It is the Silver Skin of Binding! It fixes all! If it moves and shouldn't, use the Silver Skin! If it should move and doesn't, use the Boom-Powder!"
"If it moves and shouldn't," Pinch countered, trembling with rage, "you calculate the Burden of Weight and install a stone pillar! You savages!"
The courtyard erupted.
"SAVAGES!" the Crabs clicked, clacking their claws like war drums.
"NERDS!" the Goblins screamed, waving their hammers.
The Goblins didn't actually know what a "Nerd" was. They had just heard Aris use the word once when he was frustrated with his homework back in the tower. They assumed it was a terrible ancient battle cry meaning "He Who Kills With Books."
Aris looked at Kaelen, panic rising in his chest.
"I can't do this," Aris whispered, his voice cracking. "I'm just a student, Kaelen! I take tests! I write essays about bridge loads! I don't stop race wars!"
"You're a King," Kaelen smiled, handing his parasol to Lyra. "And Kings have me."
Kaelen stepped forward. He didn't shout. He didn't draw his Void-Blade. He simply... projected.
"Gentlemen! And Arthropods!"
His voice wasn't loud, but it hit them like a physical wave of mana. It was the voice that had convinced nations to lay down arms. It was the voice of the First Hero.
Every head turned.
"Aris," Kaelen said conversationally, pointing up. "Look at the sky. Tell me what you see."
Aris blinked. "Clouds? The sun?"
"No," Kaelen grinned. "You see a giant hole in the roof where the last privy exploded. My point is... we are all living in a drafty, yellow ruin that smells like wet dog. Krakka, your boys have the energy of a thousand exploding suns. Pinch, your people have the precision of a master jeweler. If you fight, you create a mess. If you work together... you might just build a latrine that doesn't try to assassinate me while I'm reading the morning scrolls."
He patted Pinch's shell. "And Pinch, think of it this way: If you fix the plumbing, you never have to look at their wobbly pipes again."
"A compelling argument," Pinch clicked thoughtfully. "The existence of the wobble offends me more than their smell."
"Excellent," Kaelen stepped back, winking at Aris. "All yours, Boss."
Aris stepped up on a crate. He took a deep breath, trying to channel his inner professor.
"Project Royal Flush," Aris announced, his voice trembling slightly. "Crabs handle the Angles. Goblins handle the Fire-Welding. If anyone eats anyone else, Lyra will deduct it from your soul-pay."
The next six hours were a chaotic symphony of cross-species cooperation.
Lyra took charge of Administration. She stood in the middle of the yard with a clipboard, looking like she wanted to banish the entire universe to the Void.
"No," Lyra said firmly to a Goblin. "You cannot use a Crab as a ladder. Get down."
"But he has grip!" the Goblin argued, clinging to a Crab's back.
"I am not a step-stool!" the Crab shrieked. "I am a High Architect of the Third Order!"
"You are a step-stool if you don't move that pipe," Lyra snapped. "Move."
Elowen found a group of Goblins arguing with a Crab about a pipe that wouldn't fit into the joint.
"It fits if we hit it!" the Goblin shouted, raising a mallet.
"It is too wide by a hair's breadth!" the Crab clicked. "It requires shaving!"
Elowen drifted over, her robes floating in unseen wind. She leaned in close to the Goblin.
"You know," she whispered, her eyes glowing with mischievous blue light. "You really shouldn't hit that pipe. The Tiny Metal Spirits live inside it."
The Goblin blinked. "Spirits?"
"Yes," Elowen nodded gravely. "They are very small, very spiteful ghosts that hold the iron together. If you hit them too hard... they let go. And your hand turns into a chicken."
The Goblin stared at his hand. He stared at the pipe. He dropped the mallet and ran away screaming. "THE PIPE IS HAUNTED! SAVE THE CHICKENS!"
Elowen giggled. "The superstition of the uneducated is so exploitable."
Garrick was hovering over the trench-digging team, offering unhelpful commentary from ten feet in the air.
"You missed a spot," Garrick pointed lazily.
"We removed exactly 400 stone-weights of earth," the Crab drone argued. "The pit is perfect."
"Yeah, but look at that rock," Garrick grinned. "It looks suspicious. I bet it's plotting treason. Better blow it up just to be safe."
Suddenly, Thal materialized from the shadow of the trench. He didn't look at the rock. He stared into the dark, spiraling stairs leading down to the new septic tank.
"I don't trust those stairs," Thal rasped, his voice sounding like gravel grinding on bone.
"Why?" Garrick asked, floating down. "Are they unstable?"
Thal looked at him, his masked face unreadable. The shadows around him seemed to darken.
"No," Thal whispered gravely. "They're always up to something."
Garrick stared at him. The Crabs stared at him. Even the wind seemed to stop in confusion.
"Did..." Garrick gasped, clutching his chest. "Did the Shadow of Death just make a dad joke?"
Thal pulled his hood down further and merged back into the darkness. "I said nothing. You heard nothing."
By sunset, the system was built.
It wasn't pretty—it was a Frankenstein monster of white marble pipes and rusted iron joints—but it was straight.
Aris stood before the main valve. His hands shook slightly. This was it. The first real infrastructure of his reign.
"Opening Main Valve," Aris announced.
He turned it. CLUNK.
There was a hiss of air. Then, a low rumble.
Gurgle... Gurgle... WHOOSH.
Water rushed through the pipes. It didn't leak. It didn't explode. It didn't wobble.
"The Silent River..." King Pinch whispered, weeping milky fluid from his eyes. "Do you hear it? There is no turbulence. It sings the Song of Peace."
"IT WORKS!" Krakka screamed, dancing a jig. "IT IS FAST! IT HAS SPEED!"
Then, the miracle happened. Krakka walked up to King Pinch. The Goblin Warlord looked up at the giant Crab King.
"Hey. Shell-Face," Krakka grunted. "You... did good math."
"And your fire," Pinch conceded, polishing his monocle. "It was... adequate. You have passion. Chaotic, messy passion. But passion."
"We don't eat you," Krakka decided generously.
"Eat us?" Pinch recoiled. "You intended to consume us?"
"Yeah," Krakka nodded. "But then we remembered... Void-Beasts don't eat Jesters."
Pinch stared. "Jesters? We are Geometers!"
"Because they taste funny!" Krakka roared with laughter, slapping his knee.
The Crabs stared in silence.
"...Your humor is inefficient," Pinch clicked. "But I accept your truce."
He raised a claw and awkwardly tapped Krakka's shoulder.
Lyra lowered her clipboard. "They're bonding. I don't know if I should be happy or terrified."
"Happy," Aris said, leaning against the valve, absolutely exhausted. "Definitely happy."
Eve appeared at his side, holding a fresh towel.
"Congratulations, Master," she said dryly. "You have conquered the greatest enemy of civilization: The Runs. However, we have a new problem."
Aris wiped the sweat from his forehead. "What is it now?"
"Census data," Eve flipped a page on her clipboard. "We currently have 5,000 Goblins. And as of this afternoon, we have added exactly 2,843 Giant Crabs to the populace. That is a lot of hungry mouths."
Aris paused. He looked at the courtyard, now a sea of green skin and white shell. His mind, trained in modern logistics, instantly started running the numbers.
"The burgers I summoned are gone," Aris muttered, rubbing his chin. "What about the Void-Golem? The one Krakka's hunting party took down last week?"
"We are down to the gristle, Boss," Krakka burped, patting his stomach. "Very chewy. Tastes like angry rocks. Maybe last two days."
"Two days," Aris repeated. "Then we starve."
He looked at the Crabs. They were aquatic creatures in a dry wasteland. They were already huddled near the new water pipes, trying to absorb moisture from the air.
"We need infrastructure," Aris murmured, his eyes scanning the layout of the castle. "The Crabs can't live in the barracks; they'll dry out. And the Goblins can't keep eating Golem-Gristle; they'll get scurvy... or rock-sickness."
"We need a farm," Kaelen said, walking up and handing Aris a piece of dried Golem jerky. It was grey and looked like a shoe sole. "But nothing grows in the Void-Soil. It's dead earth."
Aris took the jerky. He didn't eat it. He looked at the new plumbing system—the fresh water flowing through the pipes, and the waste water flowing out.
"The soil is dead," Aris agreed, a small smile forming on his tired face. "But the water isn't."
He looked at King Pinch.
"Pinch," Aris called out. "Do your people know how to build large, watertight reservoirs?"
"We build the Tanks of Reflection," Pinch clicked proudly. "They hold water for centuries without a drop lost."
"Good," Aris nodded, his mind already drafting blueprints for a massive Aquaponics system. "Because we aren't going to farm the land. We're going to farm the water. But first..."
He took a bite of the Golem jerky. It crunched like gravel.
"First, we sleep," Aris groaned. "Because I can't invent agriculture on an empty stomach."
"Agreed," Kaelen laughed, patting him on the back.
As the sun set over the Abandoned Continent, casting long shadows over the yellow castle, the sound of clicking claws and goblin laughter filled the air. It was a strange, discordant harmony. But for the first time in a thousand years, the plumbing worked, and the King had a plan.
