Seilus is a planetary system orbiting a yellow G-class star.  The system lies in the Carina Constellation of the Achernar Region.

Seilus is a junction system that connects the Achernar Region with the Canopus Region.  The system has been home to a partially habitable moon that orbits an usually large, terrestrial world.  The icy moon has housed a small population.


The majority of the population consists of scientists and their families.  The system's busy recharging and jump stations are located outside of the inner worlds.  Interstellar travellers often visit the stations in large numbers.
