Helius Cluster

The Helius Cluster is a particularly dense cluster of 3.4 billion stars in the Valan-Onira Arm of the Astrias Galaxy. The Helius Cluster is home to a density of sapient and non-sapient life seen nowhere else in the Astrias Galaxy, with the League of Vaniri Worlds regarded as the only exception. There are multiple theories as to why this particular portion of the galaxy is so dense with both life and habitable worlds, the most prominent of which posits that the ruins on many of the planets in this Cluster and the gates which dot a number of systems are a sign of prior habitation by a more advanced ancient intergalactic power.
