Kharu Warden were the regulators of this world, the beings responsible for enforcing the rules that governed life in Thalvoria and every other human settlement beneath the Tower. No one truly knew what they were or where they had come from, and despite the years humanity had spent in this place, the Wardens had never offered an explanation.
What everyone knew for certain was that they were not human.
The moment one laid eyes on a Kharu, that truth became impossible to ignore. Their bodies resembled polished stone carved into the shape of armored humanoids, their surfaces smooth and pale like marble statues brought to life. Yet despite their seemingly rigid forms, their movements carried an unsettling fluidity, their joints bending and turning with an unnatural grace that stone should never possess. Beneath the pale surface of their bodies ran faint glowing lines, thin veins of light that pulsed slowly beneath the stone as though some unknown energy flowed through them.
They did not eat, they did not sleep, and as far as anyone could tell, they did not care about the things humans cared about.
And yet they were everywhere.
One could see them standing silently in the markets, watching the crowds move between stalls, or positioned near the dungeon gates where adventurers gathered before their daily descents. Others appeared inside clinics, ensuring order among the wounded, while some oversaw supply stores like DelveMart, quietly managing stock and maintaining security. Their presence had become such a constant part of life that people rarely questioned it anymore, though the unease they inspired never truly faded.
From the moment humanity first arrived in this strange world, the Kharus had already been there waiting.
They were the ones who established order in the chaos that followed humanity's arrival. Shelter was assigned to every newcomer, food distribution was organized to prevent starvation, and people were given various forms of work so that the growing settlements could function. Most importantly, the Kharus created the laws that governed the cities built beneath the Tower.
And those laws were absolute.
Interestingly, the Wardens never interfered with dungeon expeditions. Adventurers could enter the Tower, risk their lives, and die on its floors without a single Kharu stepping in. The Tower was treated as a domain where survival depended entirely on one's own strength.
However, the moment someone broke the laws of the city itself, the Wardens acted without hesitation.
Acts such as violence, theft, assault, or even threatening a Kharu were met with swift punishment. There were no trials, no negotiations, and certainly no second chances once a Warden had determined someone had crossed the line.
Most punishments came in the form of crippling system penalties that could last months or even years. Offenders might find their levels reset, their abilities sealed, or their progression halted until they complete exhausting labor assigned by the Wardens. Some criminals were forced into work camps beyond the safety of the city walls, performing harsh tasks that few adventurers would willingly accept.
And for the worst crimes, the punishment was far simpler.
The offender disappeared.
Adrian had never personally witnessed a Kharu Warden kill someone, but he had seen enough people vanish after defying them to understand the reality of the situation.
For most people living in Thalvoria, disappearance and death were practically the same thing.
The Kharu manager slowly turned its head toward Adrian as he entered the store, the faint lines of light beneath its polished stone surface shifting subtly as its glowing eyes settled on him. For a brief moment, the strange being simply observed him in silence, its expression as unreadable as ever, before turning back toward the shelves and continuing the quiet task it had been performing when Adrian arrived.
There was no greeting.
No acknowledgment.
Only work.
Adrian slipped behind the counter without a word, setting down his bag beneath the register as he prepared for the start of another shift. The silence inside the shop did not bother him in the slightest. In fact, it was one of the reasons he liked working here in the first place.
A talkative manager would have driven him insane.
Spending hours dealing with chatty customers every day was exhausting enough as it was, and Adrian had little patience for unnecessary conversation once his shift began. The Kharu, on the other hand, suited him perfectly. It spoke only when absolutely necessary and seemed to care about nothing beyond maintaining order inside the store.
Its role was simple but important.
The Kharu managed inventory, ensuring that supplies were always stocked and properly organized. It monitored deliveries from dungeon scavengers, kept track of incoming shipments, and quietly handled any situation where customers grew too aggressive or disruptive.
Adrian handled everything else.
The arrangement had worked smoothly for years, and neither of them had ever shown any interest in changing it.
Leaning lightly against the counter, Adrian watched as the first customers of the morning began to filter into the store. It never took long for DelveMart to fill with adventurers preparing for their daily dungeon runs, and the familiar routine unfolded exactly as it always did.
A pair of rookie adventurers approached first, both still wearing the slightly nervous expressions common among people who had not yet spent enough time inside the Tower to lose their fear of it.
"Two stamina potions," one of them said as they placed a few coins on the counter.
Adrian nodded and rang up the purchase with quiet efficiency, sliding the potions across the surface once the transaction was complete.
One of the girls leaned forward slightly, resting her elbows on the counter as she studied him with a playful smile.
"Are you always this serious?"
He handed her the change without so much as acknowledging the question.
"Next."
Her friend immediately burst into laughter.
"Told you," she said, nudging the other girl in the arm. "He's like a walking stone."
It was a familiar exchange, one Adrian had experienced more times than he cared to count. People often tried teasing him just to see if they could get a reaction out of him, but he rarely gave them the satisfaction. Over time, most of the regular customers had simply accepted that this was the way he was.
Straight to business.
No nonsense.
No pointless conversation.
Just work.
The door opened again, the small bell above it chiming softly as another customer stepped inside.
Adrian glanced up toward the entrance.
A tall man stepped inside the store, brushing a bit of dust from his shoulder as he walked toward the counter. Adrian recognized him immediately. The man was one of the regular adventurers preparing for the raid on Floor 20, someone who had been steadily climbing the Tower for quite some time and had built a decent reputation among the lower-floor explorers.
He was also one of the few customers Adrian spoke to more than once.
"Hey, Adriano." He greeted.
"Ronan," Adrian replied curtly.
Their relationship was an odd one. The man did most of the talking while Adrian simply listened. Whenever he came to DelveMart, he would lean on the counter and begin recounting his latest dungeon run in surprising detail, describing the monsters his party had fought, the traps they had nearly triggered, and the close calls that had almost cost someone their life. Sometimes he talked about the friends they had lost along the way, speaking of them with a strange mix of sadness and pride, as though their deaths were both tragic and inevitable.
Adrian rarely responded with more than a nod or a brief acknowledgment, yet the adventurer never seemed bothered by the one-sided conversation. If anything, he appeared to enjoy having someone willing to listen without interrupting.
Over time, Adrian had heard more dungeon stories than most people who had never even stepped inside the Tower.
Ronan approached the counter with a familiar grin and began placing several items down one by one—healing potions, antidotes, a replacement dagger, and a bundle of rope.
"Big day today," he said casually. "We're finally challenging floor 20."
"Is that so?"
Adrian replied mindlessly, scanning the items, and Ronan leaned against the counter while Adrian rang up the supplies, clearly ready to launch into another story.
"You should've seen the monsters we ran into last week on the ninth floor. Ugly things, as someone mashed together a....
