This is the basis for the Family Seat of the Count of Endymion Cluster. It is AI generated so I can use as much or as little as I want. Since I generated it, I don’t have to worry about copyright infringement if I use some/none/or all of it. I won’t use all the details. I won’t use the illustration without getting it modified. I probably will use it to inform the descriptions of things that take place inside it during Selene Unchained. One thing I will definitely change is that the entrance is from below, where the Endymion Cluster transit tube station is.

Overall Structure

Set into the crater wall itself, the mansion is a stacked honeycomb of chambers, galleries, and pressure-sealed halls. From the exterior, only a few armored windows and a shimmering energy veranda are visible; most of the estate is tunneled inward, blending neo-Victorian ornamentation with gravity-defying tech, pneumatic systems, glowing brass conduits, and gaslamp-inspired lighting strips.

A thousand years have passed since the Fall—when most lunar settlements went silent, their domes collapsing, their pressure systems failing, their reactors burning themselves out or sputtering into cold darkness. Endymion Crater has been untouched for centuries, save for ancient dust storms drifting lazily across its basin.

Yet the Aerie endures.

FIRST ENTRY INTO THE ENDYMION AERIE — 1000 YEARS LATER

The expedition’s boots sink into fine grey regolith as they approach the carved opening halfway up the crater wall. Their helmet lights sweep across the once-grand façade: a fused-glass veranda fractured into spiderweb patterns, brass ornamentation dulled to a blackened patina, the mansion’s original glow long since extinguished.

A gentle flicker interrupts the darkness—the docking proximity sensors.
Somehow… there is still power.

A faint, low hum resonates through the stone.

When the explorers breach the entrance lock, its pressure doors grind open with the slowness of ancient machinery. A yellowed holographic welcome banner stutters to life, flickering between languages lost to time. The air that spills out carries a dry, metallic scent—thin but breathable thanks to millennia-old systems struggling on remnants of power.

Inside, the Grand Rotunda is a cathedral of faded opulence. The central orrery still turns, though barely: its gears—once brass-bright—now brown with oxidation. Celestial spheres jerk instead of glide, and a few smaller moons hang motionless, frozen mid-orbit. A haze of dust hangs in the low gravity, drifting slowly with every footstep.

And then the Aerie speaks.

A ghostly butler’s voice—its diction still elegantly Victorian—echoes through the hall, distorted by ages of degradation:

“We… welcome… distinguished guests… to the Endymion Aerie.”

The mansion’s automated attendants struggle to fulfill programs written ten centuries before.
Mechanical arms, stiff with corrosion, attempt to take nonexistent coats.
A drone butler glides forward on trembling stabilizers, its once-polished shell flaking and scarred.
Tiny sparks jump from its eye lenses as it tries to bow.

Down the corridors, dim bioluminescent strips glow erratically—some strobing, some pulsing, others dark forever. Plants within the Moonlight Conservatory have long since died, replaced by a petrified forest of mineralized stems and ghost-white leaf imprints. Yet a few sealed hydroponic tanks still gurgle faintly, tended by loyal robotics who never understood that their garden had been dead for centuries.

In the Nebula Ballroom, gravity plates malfunction.
One moment the explorers feel heavy; the next, they drift upward, surprised, boots scraping the domed ceiling.
Shattered chandeliers float freely in the intermittent zero-g, spinning like crystalline nebulae.

Deep within the Private Library, thin motes of dust swirl in currents created by neglected air recyclers. Book spines crack at a touch. The pneumatic retrieval system hisses once, then dies mid-cycle, leaving a brass tube clattering weakly.

Yet despite the decay, signs of the Aerie’s stubborn resilience are everywhere:

• The reactors—far beneath the living areas—still pulse with a faint, steady heartbeat.
• Pressure seals, though aged, still hold.
• The Aerie’s AI, though fragmented and glitching, still attempts to care for its absent master and any visitor it believes worthy.

Occasionally, speakers emit a half-formed memory of the mansion’s glory days—laughter, chamber music, the distant echo of a gala—audio files corrupted into eerie, dreamlike fragments.

As the explorers descend deeper, they encounter rooms sealed for centuries, their contents untouched: a guest suite with bedding still neatly arranged; a dust-coated lounge with glasses waiting for a party that never came; an automaton pianist slumped over a keyboard, fingers paused above yellowed keys as though waiting for applause.

The Aerie is not a ruin in the usual sense.
It is a mausoleum of luxury, kept alive through sheer mechanical loyalty—a palace waiting for guests who will never return.

And now, after a thousand years, it has guests once more.
