Isirin is a Class M star in the Sagittarius Dwarf Elliptical Galaxy. Using a superpowerful telescope on a tall mountain on Krar, the Karalian Empire was able to detect planets here, and has become the first target of an extragalactic expedition.

The star system is located at a nexus of Ritosian-Matrion-Xavin territories.



Zythron is a close orbiting planet which is wrecked with volcanism. The entire planet is covered in molten metal and has become a good candidate for a forging planet much like the planet Yolkor.


A super Earth planet with a crust consisting of carbon. Its atmosphere is made of krypton and xenon. Several kilometers below its surface are large deposits of Dragonrock, which if mined out, can be exported to Zythron for refinement.


Sutham is gas giant slightly larger than Neptune. Found in Isirin's habitable zone, it has a moon, Mathus, which can support life.


Main article: Mathus

Mathus is a moon covered in fields of lichen and algae. Life is primitive, yet well developed. Tree analogues consist of towering lichen stalks which provide it a basic atmosphere of nitrogen and oxygen.


Galvan is a large ocean planet at the edge of the habitable zone. It has developed an ecosystem of invertebrate and fish analogues near the planet's core. As a result, most life on this planet relies on geothermal heat rather than sunlight.
