Day 28.
The population boom had brought life to Fort Blackiron, but it also brought a terrible enemy: The Stench.
Walking through the newly built communal longhouses, Rian had to cover his nose. 268 people, mostly unwashed former bandits and slaves, living in close quarters. The air was thick with the smell of sweat, grease, and old fish.
"Lara," Rian stood outside, taking a deep breath of cold fresh air. "The 'Law of Filth' says they must wash. Why do they still smell?"
Lara looked uncomfortable. "They do wash, My Lord. They jump into the icy river every morning. But... the grease from the mines and the kitchen doesn't come off with just cold water. It sticks to the skin."
Rian nodded grimly.
"Water and oil don't mix. You can scrub until you bleed, but without an emulsifier, the dirt stays."
If this continued, lice and fleas would breed. Typhus would follow. And then, his empire would turn into a graveyard.
"We need Soap," Rian declared.
"Soap?" Lara blinked. "The perfumed bars the Southern ladies use? That costs 1 Gold Coin a bar! We can't afford luxury."
Rian laughed dryly. "I'm not talking about rose-scented luxury, Lara. I'm talking about chemical warfare against dirt."
The Alchemist's Kitchen
Rian marched into the small stone hut assigned to Elara, the old hedge alchemist.
The room smelled of dried moss and bitter roots. Elara was grinding herbs in a mortar.
"Elara," Rian placed a bucket of white wood ash on her table. "Stop playing with moss. We are doing chemistry."
Elara peered at the bucket. "Ash? From the furnace?"
"Yes. Hardwood ash," Rian explained. "And this..." He signaled Hance to bring in a barrel of rancid fish oil (leftover from the lamps).
Elara wrinkled her nose. "Garbage and grease. You have strange tastes, My Lord."
"It's called Saponification," Rian grabbed a piece of charcoal and drew a diagram on the wall.
"Listen carefully," Rian instructed, pointing to his drawing.
The Base: "We pack this barrel with wood ash. We pour water over it slowly. The water will leach out the 'Potash' (Potassium Carbonate). The liquid that drips out the bottom is Lye."
The Reaction: "We take that caustic Lye water and boil it with the Fish Oil."
The Result: "The Lye attacks the fat. It breaks it apart. And when it cools, it becomes Soap."
Elara looked at the diagram, her alchemist eyes widening.
"You want to mix 'Caustic Water' that burns skin with oil? It will explode!"
"Only if you do it wrong," Rian smiled. "That's why you are doing it. You know how to control the heat."
The Boiling Cauldron
For the next six hours, the courtyard smelled even worse—like boiling fat.
The serfs watched in horror as Elara stirred a massive iron cauldron bubbling with a thick, yellowish sludge.
"The Lord has finally lost his mind," a former bandit whispered. "He is making soup out of lamp oil and ash."
"It's not soup, you idiot," Grom grunted, watching from his forge. "It's... magic mud."
Rian stood by the cauldron, checking the consistency.
"It's tracing," Rian noted. The mixture was turning thick, like pudding. "Pour it!"
Elara and Hance poured the hot sludge into wooden molds.
"Now we wait."
The Next Morning
Rian stood before a table. The sludge had hardened into yellowish-brown blocks. They looked ugly. They smelled faintly of fish, though the boiling had removed most of the stench.
Rian picked up a knife and cut a chunk.
The First Bar of Soap.
He walked over to Varg, who was covered in soot from helping Grom. His hands were black with grease that no water could remove.
"Wash," Rian tossed the block to him. "Use warm water."
Varg looked skeptical. He dipped his hands in a bucket, rubbed the weird yellow block, and scrubbed.
Suddenly, Foam.
White, bubbly lather covered his hands.
Varg scrubbed for ten seconds, then rinsed.
He looked at his hands. The black grease was gone. His skin was clean.
"By the Gods..." Varg stared at his palms. "It eats the dirt."
"It's called 'Soft Soap'," Rian announced to the crowd. "It kills the lice. It kills the fleas. And it stops the itch."
He turned to Lara.
"Cut it into 300 pieces. Every man, woman, and child gets one. Tuesday is now 'Scrubbing Day'. Anyone found with lice gets their rations cut in half."
Lara picked up a bar. She, being a merchant's daughter, realized something else.
"My Lord," she whispered, her eyes gleaming. "This cost us nothing. Just ash and trash oil. But in the South... peasants would pay copper coins for this. It stops the itching."
Rian nodded.
"We use it first. We sell it later."

[New Product: "Blackiron Soap" (Grade: Low, but Effective)]
Rian looked at his clean hands.
First, he gave them Warmth (Greenhouse).
Then, he gave them Food (Barley/Fish).
Then, Safety (Bandits/Walls).
And now, Dignity (Cleanliness).
Civilization was rising from the dirt, one bubble at a time.
