Sefira is a planetary system orbiting a yellow G-class star.  The system lies in the Aquarius Constellation of the Schemali Region.

The primary planet of the Sefira System is a relatively young world whose land masses are covered in a complex network of mosses and algae.  Originally settled by a group of geologists looking to the study the world, its population has since grown at a steady pace over the years.


A series of small colonies make of the bulk of the population, with large cities few and far between.  The colonies produce their own food and resources, they are largely self sufficient and independent from the other colonies.

Sefira C
C is a habitable, terrestrial word that formed after planet b migrated inward.  Covered in 70% water, a complex network of green mosses and algae cover the land masses of the young world.  Small colonies stretch across the planet adding up to a significant population.
