Hecate
Hecate is a rogue planet that appeared in Cardassian space in 2397. The USS Veritas under the temporary command of Lt. Commander Jansen Orrey was ordered to investigate the planet as it passed through Federation territory.
The planet showed the strange ability to go into a subspace layer that allowed the planet to travel great distances in a short time. While not on the subspace layer, the planet travelled as a normal celestial body, however, it seems to be attracted to certain magnetic fields produced by warp drives.
On the surface, the crew of the Veritas discovered some sort of ruins that seemed to be related to the Menthar civilization with at least one dome that preserved some sort of atmosphere around the ruins, however humanoid lifeforms couldn't withstand the conditions and should wear EVA suits to be on that surface.
It was also discovered that there was some sort of lifeform that has been technologically altered. The extent of those alterations are still being investigated.
Physical Characteristics
Atmosphere
The natural barometric pressure of the planet is high. Starfleet EVA suits are not capable of withstanding the atmospheric pressure.
Diamond lakes
Along the equator of the planet are located several lakes composed of liquid diamond.
Low Atmospheric Pressure "Domes"
Next to one of the lakes, several artificially generated "domes" exist. They are artifically generated atmospheric "bubbles" that use an energy shield to maintain an atmospheric pressure of approximately 1,000 hectopascals. They appear to have been constructed to support life forms, however the thick foggy atmosphere inside the domes are still hazardous, requiring people to wear EVA suits. The surface inside the domes consist of a graphite like dark grey sand, that has shiny flecks in it. The outside atmosphere appears like thick dense smoke.
Ruins
Located within one of the domes is an upside down dark grey “L” shaped two storey building, approximately 20 meters in height. The second story is longer than the first storey and has partially fallen away - a pile of the building’s material is located underneath the second level.
Life Forms
The planet sustains an unknown biological life form, seemingly silicon based, that contain approximately 13 percent artificial components largely composed of diamond. It is suspected that it has an unknown cloaking capability.
