Daedalus

Daedalus is a moon orbiting a has giant far from Reticulum space. It was the homeworld of the ancient Phyxx.

Daedalus is protected from orbit by 3 dropships full of space marines: Roenick, and Chelios, dispatched from a Mondite world.

History
During the height of the Phyxx civilization, they mastered the moon's gravity, and they based their technology on those effects. They dwelled floating cities, but they were destroyed during the Age of Drastic Upheaval, and relocated underground.

After the disappearance of the Phyxx, the gravity technology had remained uncontrolled for millennia. The long-range side effects turned the moon's surface barren and nearly lifeless.

The Mondites discovered Daedalus after tracing the origin of an ancient explorer ship of the Phyxx. They established an isolated base there and kept its location secret.

Geography
The main opening to the Gravity Tunnel was built on its north pole. From orbit it looks like a basin, not unlike an inactive volcano, as the Mondites believe. They discovered archeological ruins there, the remnants of the Phyxx station.

Underground
has never had a molten center, yet geographic analysis shows massive geological instability enduring a thousand centuries.

a massive underground construction: two hollow rings beneath this moon's surface encircle the entire planet. One of them runs exactly north to south, the other runs along the equator. Together they look like the rings of a gyroscope. The gravitational ring runs beneath the circumference of the planet that can be used to accelerate extraplanetary craft to speeds that would enable them to escape our gravitational pull

The equatorial ring has been broken in so many places over a period of thousands of years that is has been virtually destroyed due to the geological instability. The north/south ring is worn and strained in many places, yet is still intact, a marvel of engineering.

Flora and fauna
Daedalus appeared a barren dry planet. Its environment cold not tolerate moisture, producing hostile fungi. Many animal species of Daedalus appear to be immune to toxin.
