Chapter 4: Taxes, Traps, and a Functional Bathroom

Morning in the former Demon Lord’s fortress arrived like a rumor rather than a sunrise.

The light that reached Nate Mercer’s room had to fight its way through arrow-slit windows, old storm glass warped with age, and a lacework of ivy that had claimed half the outer wall. What made it through spread in green-gold bars across a chamber the size of a studio apartment and landed directly across Nate’s face.

He opened one eye, saw a ceiling thirty feet overhead painted with flaking constellations, and for one irrational second thought he’d slept in a museum after a team-building event gone wrong.

Then the bed adjusted under him.

It gave a contented little huff, like a giant dog settling in, and warmed itself another degree.

Nate stared at the canopy above him.

“Right,” he muttered. “Demon castle. Magic bed. Tuesday remains committed to the bit.”

Across the room, Vexa was already awake.

She stood by the window with her arms folded behind her back, her silhouette cut from the pale dawn: tall, horned, long dark hair tied with military precision, tail still as a held blade. She wore yesterday’s black uniform coat as if she had been born in it, which was annoying because Nate had spent a good ten minutes before sleeping trying to get the cloak clasp on his own borrowed lordly outfit to stop choking him.

She glanced over when she heard him move. “You live.”

“That sounds less encouraging when you say it like a disappointed coroner.”

“I was taking inventory,” Vexa said. “Your species appears fragile.”

“We are. It’s one of our defining traits.” He pushed himself upright and discovered, with all the force of revelation, that he had not slept on stone, straw, mold, or vague historical regret. He had slept on a mattress. An actual mattress. “Okay. No. Hold on. This bed is incredible.”

Vexa’s expression did not change, but one pointed ear twitched. “It is a bed.”

“No, it is a miracle. Yesterday this room looked like a haunted tax write-off.” Nate swung his legs over the side and planted his feet on a rug so thick his toes vanished into it. “I know I used the settlement thing to patch stuff, but I was mostly blacking out from stress. Did I upgrade my own bedroom into a luxury suite?”

The glowing text appeared in the air over his blanket in cheerful blue script.

Nate pointed at it. “See? That. That’s the kind of thing I mean. It just keeps saying words and numbers like I’m expected to have gone to wizard HR orientation.”

Vexa looked at the floating message without surprise. “Ancient territorial authority systems always favored incomprehensible confidence.”

“That sentence somehow made it worse.”

He stood, stretched, and felt an alarming number of muscles fail to complain. Yesterday he had hauled rubble, walked half the fortress, accidentally become the legal owner of cursed demon real estate, hired a former enemy general, and eaten soup cooked in a kitchen older than several nations. He should have felt like roadkill. Instead he felt… rested.

It was suspicious.

He walked to the washstand in the corner, lifted the porcelain pitcher, and found it full of warm water.

Nate slowly looked at the basin. Then at the pitcher. Then back at Vexa.

“Did you fill this?”

“No.”

“Did the castle fill this?”

“Likely.”

He stared at the water as if it might confess. It smelled faintly of mint. “I know my standards collapsed pretty fast after dying and waking up in fantasy Mordor, but I’m weirdly emotional about plumbing-adjacent behavior.”

Vexa turned from the window. “If you are done worshipping the basin, there are priorities.”

“Yes. Absolutely. Priorities.” Nate splashed his face, yelped at the warmth, and then sighed from somewhere deep in his soul. “First priority: do we have a bathroom, or am I about to discover medievalism in the worst possible way?”

That earned him Vexa’s full attention.

“A what?”

Nate lowered his hands very slowly. “You know. A room. For… bathroom activities.”

“We have a garderobe shaft.”

“I hate both of those words together.”

Vexa’s mouth edged toward what, on any other face, might have been a smile. “It is down the hall. It drops into an oubliette pit that has not been serviced in approximately—”

“Nope.” Nate held up a hand. “No. Absolutely not. New first priority: inventing indoor civilization.”

He marched into the corridor in his shirt sleeves with the grim purpose of a man who had suffered enough. The hallway beyond his room stretched broad and dim between pillars carved with scenes of horned warriors and coiling dragons. Dust still lingered in the grout despite yesterday’s restoration, but the cracked tiles had knitted themselves back together overnight in jagged seams of black stone. Thin witchlights hovered near the ceiling, their violet flames reflecting in spear racks and old brass sconces.

Every few steps the fortress seemed to wake around him. A shutter unlatched with a click. Somewhere below, a pulley began to move. Far off in the courtyard, chains groaned like the castle was rolling its shoulders.

It was unnerving.

It was also, Nate had to admit, kind of awesome.

They reached the garderobe. The smell met them first.

Nate stopped dead.

There were battlefield horrors less persuasive than that smell.

The narrow stone chamber held a cracked seat over a vertical shaft and not much else, unless one counted despair as furnishing. Something skittered in the darkness below. The air had layers. Some of those layers felt sentient.

Nate backed out, closed the door, and leaned his forehead against the wood. “I need a permit to be this offended.”

Vexa crossed her arms. “I did say it was old.”

“This is not old. This is a war crime with hinges.” He exhaled, straightened, and looked down the hall with sudden, holy resolve. “Okay. Fine. I have a broken city-builder god skill and a tax base of one emotionally unavailable demon woman. If there was ever a time to abuse executive authority, it is now.”

He reached for that strange internal sense he’d found yesterday: the map-like awareness of rooms, materials, structure, occupancy, latent systems sleeping under stone. It was like flexing a muscle he shouldn’t have possessed. The fortress bloomed in his mind in translucent layers—walls, conduits, cisterns, old rune lines, sealed workshops, dormant furnaces. A network of possibilities shimmered under everything.

When he focused on the garderobe, options burst open in a cascade of glowing script.

Nate blinked. “Defensive what now?”

“What is it?” Vexa asked.

“Apparently if I build a bathroom, it can become a weapon.”

She considered that for a moment. “That is the most demon-architect sentence I have heard in fifty years.”

“Good. Great. We’re doing it.”

Nate held out a hand toward the rancid door and said the only thing that felt remotely appropriate. “Upgrade.”

The fortress answered.

It started in the walls—a pulse, low and resonant, like a giant heart remembering its rhythm. Dust leapt from the mortar. The old door dissolved into motes of red-gold light. Stone flowed. That was the only word for it. The wall beside the chamber folded inward like clay beneath invisible fingers, reshaping itself into smooth dark panels veined with silver runes. The floor rippled flat. The smell vanished in one violent breath as a draft of clean air roared through newly opened vents.

Copper pipes threaded themselves through the wall in bright spirals. Glazed ceramic blossomed into place. A broad basin formed first, then a deep soaking tub with clawed feet shaped like drakes, then—blessedly, gloriously—a toilet.

Not a hole. Not a pit. A real porcelain throne with a polished wooden seat and a tank etched in tiny script.

Nate almost cried.

Water rushed somewhere overhead and then cascaded in a silver stream into the basin. Steam ghosted up from the tub as if the room had just exhaled. The whole chamber smelled of clean stone, cedarwood, and the impossible luxury of not getting dysentery.

At the far end, a mirror irised into being in an obsidian frame. Shelf niches extruded from the wall carrying folded dark towels and little jars whose labels glowed in infernal calligraphy. A brass lever by the tub bore an engraved plaque.

Hot.

Another beside it: Cold.

Nate gripped the doorframe and whispered, “I have seen the face of God and it is indoor plumbing.”

Vexa stepped into the room with the cautious solemnity of a general entering a shrine. Her boots made no sound on the heated tile. She touched the edge of the basin. Warm water splashed over her knuckles. Her eyes widened a fraction.

For Vexa, that was the equivalent of a dramatic gasp and a backflip.

“This fortress,” she said quietly, “did not have this even in its prime.”

“Then frankly its prime had issues.” Nate approached the toilet reverently. “Please tell me this doesn’t somehow open directly over the oubliette.”

Due to seat of authority status, all core habitability upgrades reinforce territorial ward lattice.

Nate read the last line twice. “Wait. Comfort upgrades strengthen defenses?”

Vexa’s gaze shifted toward the ceiling, as if she could feel the change moving through the fortress. “Of course they do.”

“No, no, I need you to remember I know nothing. You can’t keep saying ‘of course’ like I attended evil castle management school.”

She glanced at him. “A territory’s heart is its seat. If the ruler’s hall decays, authority weakens. If the hearth goes cold, wards fail. If water fouls, spirits of the land sour. Strongholds are not stone alone. They are oaths made habitable.”

Nate stared at her, then at the shining bathroom. “That was weirdly poetic for a sanitation explanation.”

“Military academies required a broad education.”

“Demon generals had liberal arts?”

“We had standards.”

Nate snorted. Then his stomach chose that exact moment to remind him he had not eaten since dawn on another planet. The sound was audible enough that even the tub seemed to judge him.

Vexa turned. “Kitchen?”

“Kitchen,” Nate agreed. “Then we fix whatever else separates this place from basic occupancy law.”

The castle made progress easier than any renovation had a right to be. Once Nate understood the shape of his authority, the work came in surges. A ruined servants’ hall became a bright dining chamber with long blackwood tables and lamps that glowed like banked coals. The kitchen, which had already partially restored itself yesterday when he’d panicked at the sight of broken ovens, expanded into a proper fortress-grade culinary complex with enchanted chill cabinets, sharpened prep stones, and a stove that ran hot enough to make Vexa visibly respectful.

That was how Nate discovered that one of the simplest ways to shake a former demon general’s composure was to produce a pantry.

“Flour,” Vexa said, opening one cupboard.

“Usually a pantry has that, yes.”

She opened another. Dried mushrooms. Another. Salt in ceramic crocks. Another. Oil. Lentils. Smoked meat. Root vegetables hanging in netting, somehow fresh.

“There is organization,” she said, with grave wonder.

“Try the labels.”

Vexa stared at the neat infernal script burned into each shelf edge. She reached up, touched one, and went very still. “It updates by quantity.”

“Oho. We’re in spreadsheet country now.” Nate leaned against the counter. “Welcome to my area of expertise.”

She gave him a look. “You say this as if it is a threat.”

“It often is.”

Breakfast became an unexpectedly peaceful thing: Vexa at the stove in rolled sleeves, moving with exact, economical precision, frying flatbread in herb oil while a pot of something savory bubbled. Nate sat at the long counter, trying not to think too hard about how fast his life had gone from quarterly reports to demon fortress domesticity.

Outside the kitchen windows, the courtyard lay under a thin veil of morning mist. Weed-choked flagstones had been partially reclaimed. A dead fountain stood in the center, still cracked and dry, but yesterday’s repairs had straightened the surrounding arches and resealed the gatehouse. High overhead, ravens perched on battlements and watched as if waiting for the management style of the new lord to become embarrassing.

“Question,” Nate said around his first bite of crisp, steaming flatbread. “When you said people might come here because this place reactivated, how bad are we talking?”

Vexa slid him a bowl. “Bad depends on the people. The Blighted March attracts scavengers, exiles, cultists, scholars with poor survival instincts, smugglers, monster-hunters, treasure seekers, and the occasional fool who believes the Demon Lord left a crown in a vault.”

“Did he?”

“Probably several. He enjoyed crowns.”

“That is inconveniently on brand.” Nate blew on the stew. It tasted rich with mushroom and garlic and something smoky enough to make his eyes roll back for a second. “You’re an absurdly good cook, by the way.”

Vexa looked mildly offended. “I can read instructions and understand heat.”

“Yes, and Michelangelo could dabble in ceilings.”

She ignored that. “Word will spread if smoke rises from our kitchens, if ward lights return, if roads become passable. We should assume someone will test the fortress before long.”

Nate swallowed. “Test as in reconnaissance? Theft? Murder?”

“Yes.”

“Cool.” He set down the spoon. “Then after breakfast we’re upgrading every comfort item this castle has until it becomes a home invasion hate crime.”

Vexa stared at him for a heartbeat, then laughed.

It startled him more than the magic had.

The sound was low and brief, roughened by disuse, but undeniably real. It changed her face in a way armor never could. For an instant she looked less like a relic from a defeated empire and more like a woman who remembered what having a future had once felt like.

She cleared her throat almost immediately and resumed ladling stew. “An acceptable strategy, my lord.”

“Please don’t call me that when I’m talking about weaponized throw pillows.”

“As you wish, my lord.”

By noon, the fortress had a bathhouse.

Not a modest washroom. Not a practical utility annex. A bathhouse.

It occupied an old wing off the inner courtyard that Nate had only meant to clear for laundry, but the moment the system sensed his intent, it had offered him enough options to bankrupt a small spa company.

Upgrade Available: Communal Bath Suite

Steam Chamber, Soaking Pools, Laundry Line, Dry Heat Room, Massage Slabs, Mineral Infusion Array

Territorial Synergy: Recuperation, Diplomacy, Morale, Water Wards

Warning: Luxurious civic features may attract settlers.

“That warning is not a deterrent,” Nate had said, and pressed accept.

The resulting transformation left him standing on warm slate while arched windows filled with frosted glass. Pools sank into the floor in tiers of black stone and pale steam. Pipes thrummed inside the walls. Brass faucets shaped like serpents poured ribbons of crystal water into tiled basins. Benches appeared, then towels, then laundry racks, then a shelf full of soaps in scents ranging from cedar to night-blooming flower to something simply labeled Volcanic.

Vexa had picked up a soap brick, sniffed it, and gone silent for ten entire seconds.

“You can’t tell me demon military academies prepared you for artisan bath products,” Nate had said.

“No,” she had replied, very flatly. “No, they did not.”

The system messages afterward came in a flood.

Resident Comfort +19

Nate read that last part and pointed at the glowing text. “See, there it is again. Why is every nice thing in this castle one bad mood away from becoming a military application?”

“Because this was built by paranoid immortals,” Vexa said.

“Honestly? Fair.”
