Ostence is a Class M red dwarf star in the Twin Hearts Nebula. It is an energetic young star which regularly outputs solar flares. It also has an unusually high metallicity resulting in mineral rich planets orbiting at close distances.



Monias is a small, red hot jovian planet orbiting close to its star. It orbits close enough that its atmosphere is visibly being stripped away. Over the course of the next few million years, Monias will likely be reduced to a Cthonian planet.


Gerid is a tidally locked superterran carbon planet with a steel-rich core. The planet has a layer of graphite on the surface as well as a kilometer thick layer of diamond. Its atmosphere consists of krypton and xenon.

Welthar is a type of planet with methane-based life. Welthar has vast lakes of hydrocarbon as well as an atmosphere of methane and ethane. The planet was once home to the infamous Avarith. It has three moons: Selfas, Dessir and Whant.


Korpor is a super-Earth ice world with many tall crystal spires. Regular asteroid strikes and the lack of moon will cause Korpor to topple over on its side and go into an unstable orbit within the next 10,000 years.
