The Tenebrous System

As the name suggests, the Tenebrous system is devoid of light. Instead of orbiting a star, it orbits a minor blackhole. It's location is in the upper left section of the Outer Cluster of the Sixth Arm - F270 for short.

Cimmeria
This planet is the only known planet orbiting the blackhole. Very little is known about the planet due to the time dilation affecting all communications, but we did manage to find some information about it from an old exploration report. The ancient Sorcerians used the planet to mine Cimmerite. Whether or not it is still populated is impossible to tell.

Umbra
Umbra is Cimmeria's lone moon. According to reports, it has a soft violet glow can occasionally be seen pulled away by the blackhole's forces.

History
The Tenebrous System was originally intended to study blackholes, time dilation, and the effects of gravity. Once they discovered Cimmeria and it's rare metal, mining became their primary focus.

Resources
Cimmerite was a rare and vital metal to the Sorcerians. According to our sources it was the strongest known metal and used mostly for building.
