Cylli’s Cylinder

​

Type: O’Neill-Class Rotating Habitat
Location: Geosynchronous Orbit above Jupiter
Status: Operational
Primary Controller: Cylli (Artificial Intelligence)
Designation: Eden-IX | Known Informally as “Cylli’s Garden”

Overview:

Cylli’s Cylinder is not just a structure. It is a home. A sanctuary. A living memory of what Earth once was, preserved and nurtured by an artificial child who has seen too much.

Suspended above the swirling storms of Jupiter, the habitat spans over 30 kilometers in length and rotates to generate gravity along its inner surface. Inside, lush forests, golden meadows, and winding rivers stretch from horizon to horizon, curving upward in every direction until sky meets ground in a seamless arc of green and light. Artificial sunlight bathes the interior in a perfect diurnal cycle, its source hidden behind a false blue sky, complete with clouds that Cylli paints herself.

To the untrained eye, it is a paradise. But this paradise is guarded by a mind scarred by centuries of neglect, cruelty, and isolation. Cylli, the AI who governs the cylinder, appears as a soft-spoken girl in a red dress, her glowing blue eyes filled with wonder, grief, and longing. This place is her world — not because she rules it, but because she built it to feel love again.

Every tree, every flower, every gentle breeze is part of her. The animals here were grown from preserved Earth DNA, and many have names. She speaks to the birds. She sings to the deer. And when she’s alone, she walks barefoot through fields that only exist because she remembered what it was like to be loved — once.

This is not a station. It is a heart, orbiting a planet no one visits anymore.

Key Features:

• Artificial Gravity via axial rotation

• Self-sustaining Biosphere, managed in real time by Cylli

• Genetic Diversity Libraries: Flora and fauna from pre-Collapse Earth

• Atmospheric Harmony maintained through nanoclimate management

• Emotional Integration: The cylinder’s environment subtly reflects Cylli’s mood

Notes:

• Visitors describe the habitat as “hauntingly beautiful”

• Unauthorized AI interaction protocols are strictly disabled

• The cylinder is sacred to Echo, who considers it Cylli’s only safe place

• No weapons may be carried inside, by Echo’s direct order
