The acrid stench of ozone and sweat assaulted my nostrils as I made my way through the winding alleys of the Undercity. The golden gleam of the upper levels was a distant memory here, replaced by the dull, pulsing glow of exposed Aether conduits that snaked along the walls and ceiling. Every few meters, a sparking junction box threatened to rain down a shower of golden sparks on the unfortunate souls passing beneath.

I kept my head down, hood pulled low over my face. In the Undercity, anonymity was survival. The less attention you drew, the better your chances of making it through another day without being press-ganged into a work crew or worse. My worn boots splashed through puddles of questionable liquid, the path ahead illuminated by the flickering, sickly light of cheap Aether lamps.

The deeper I ventured into the bowels of the city, the more oppressive the atmosphere became. The very air seemed to thicken, laden with the desperation and despair of countless souls. Here, in the shadow of the great Aether-Core, the lifeblood of the Solaris Dominion flowed, and we, the Aetherbound, were its unwilling conduits.

As I rounded a corner, the massive structure of the Aether-Core came into view. It was a colossal pillar of golden light, stretching from the depths of the planet to the heavens above. Even from this distance, I could feel its pull, an insistent tugging at my very essence. The Core's hunger was insatiable, and we were its fuel.

The streets widened as I approached the Core, the press of bodies growing denser. Here, in the shadow of our gleaming prison, the dregs of the Solaris Dominion gathered. Makeshift stalls lined the streets, hawking everything from stale ration bars to bootleg Aether taps. The air was thick with the babble of a hundred languages, punctuated by the occasional bark of laughter or cry of pain.

I paused at one of the stalls, eyeing a display of worn tools. The vendor, a grizzled old man with eyes that had seen too much, caught my gaze.

"Looking for something special, boy?" he rasped, his voice barely audible over the din of the crowd.

I shook my head, about to move on, when a commotion further down the street caught my attention. A group of Dominion guards, their golden armor a stark contrast to the grime of the Undercity, were shoving their way through the crowd.

"Make way!" one of them bellowed, his voice amplified by his helmet's speakers. "By order of the Solaris Dominion, all able-bodied citizens are to report for Core duty immediately!"

Panic rippled through the crowd. Core duty was a death sentence for many. The constant drain of channeling Aether into the Core left most workers hollow shells, their life force sapped away to fuel the empire's insatiable hunger.

I turned to slip away, but the old vendor's hand shot out, grabbing my arm with surprising strength.

"Quick, boy," he hissed, pulling me behind his stall. "Under here. They won't look too closely."

Without thinking, I ducked beneath the rickety table, squeezing myself between crates of rusted parts. The vendor dropped a filthy tarp over me, plunging me into darkness.

I held my breath as I heard the heavy tread of the guards approaching. My heart pounded in my chest, so loud I was sure they'd hear it.

Stolen content warning: this tale belongs on Royal Road. Report any occurrences elsewhere.

"You there, old man," one of the guards barked. "Seen any shirkers hiding around here?"

"No, sir," the vendor replied, his voice suddenly obsequious. "Just us honest merchants trying to make a living."

There was a moment of tense silence, then the sound of retreating footsteps. I waited, barely daring to breathe, until I felt the tarp being lifted.

"They're gone," the old man said, helping me to my feet. "But they'll be back. They always come back."

I nodded my thanks, still too shaken to speak. The vendor regarded me with a mix of pity and resignation.

"You're Aetherbound, aren't you?" he asked, though it wasn't really a question. "I can see it in your eyes. The hunger."

I didn't deny it. There was no point. Every Aetherbound carried the mark of their servitude, a constant, gnawing emptiness that could only be filled by channeling Aether.

I stepped out from behind the vendor's stall, my eyes darting nervously around the crowded street. The old man's words echoed in my mind, a stark reminder of the reality I lived in. I was just another face in the sea of the Aetherbound, struggling to survive in the shadows of the Solaris Dominion's golden towers.

"Thank you," I muttered to the vendor, fishing out a few tarnished credits from my pocket. It wasn't much, but it was all I could spare. He waved them away with a gnarled hand.

"Keep your money, boy. You'll need it more than I do." His eyes softened for a moment. "What's your name?"

I hesitated, weighing the risk of revealing my identity against the unexpected kindness he'd shown me. "Cyrus," I finally said. "Cyrus Venn."

He nodded, as if committing it to memory. "Well, Cyrus Venn, you be careful out there. The Core's always hungry, and the Dominion doesn't care who it devours to keep it fed."

With a final nod of thanks, I melted back into the crowd, my mind racing. I needed to find a way to avoid the next round of conscriptions, but options were limited in the Undercity. As I walked, the oppressive presence of the Aether-Core loomed ever larger, its golden light casting long shadows across the grimy streets.

The closer I got to the Core, the more desperate the scenes became. Emaciated figures huddled in doorways, their eyes hollow and unfocused. Many of them were former Core workers, their life force drained to the point where they could no longer function. The Dominion discarded them like spent batteries, leaving them to waste away in the gutters.

A commotion near one of the Core's access points caught my attention. A group of newly arrived slaves, their chains glinting in the harsh light, were being herded towards the entrance. Their faces were a mixture of fear and resignation, knowing the fate that awaited them inside.

"Fresh meat for the grinder," a voice beside me muttered. I turned to see a woman, her face prematurely aged by hardship, watching the scene with bitter eyes. "Brought in from the Frontier Nebulae, I'd wager. The Dominion's always hungry for more bodies to feed the Core."

I nodded, feeling a familiar surge of anger and helplessness. "It's never enough, is it? No matter how many they throw into that thing, it always wants more."

The woman gave me a sharp look. "Careful, boy. That kind of talk can get you a one-way ticket to the Core's inner chambers." She paused, studying my face. "You're Aetherbound, aren't you? I can see the hunger in your eyes."

I nodded grimly, not bothering to deny it. The hunger was a constant companion, a gnawing emptiness that could never truly be filled.

"Name's Lyra," the woman said, her voice low. "And if you're looking to avoid the next round-up, I might know a place."

I hesitated, weighing my options. Trust was a rare commodity in the Undercity, but desperation had a way of overriding caution.

"I'm listening," I said.

Lyra jerked her head towards a narrow alley. "This way. And keep your eyes open."

As we wound our way through the labyrinthine streets, the oppressive presence of the Aether-Core grew stronger. Its pulsing golden light seemed to seep into every crack and crevice, a constant reminder of its insatiable hunger.

"You ever wonder," Lyra said as we walked, "how many lives that thing has consumed? How many souls have been fed into its maw to keep the golden cities afloat?"

I shook my head.

We emerged into a small courtyard, hidden away from the main thoroughfares. A group of ragged individuals huddled around a flickering Aether lamp, their faces gaunt and haunted.
