Sephdar (Eta Sagittarii) is binary system in the Sargas Region consisting of red giant and a yellow/white f-class star separated by an average distance of 165 AU.  The red giant has a mass of 1.5 times that of Sol, with it's age of 3 billion years old it's nearing the end of its life.


The primary planet orbits the smaller companion star with conditions more conducive for life.  A warm tropical world that much of the planet's continents are covered in dense jungles.  The night sky is ruled by the red giant, during its closest pass the star can shine as bright as 150 full Earth Moons.
