Etharius

Etharius is the star at the center of the Proxima Aegimius system. It is by far the most important source of energy for life on all the Inner Worlds, excepting world Axis. Etharius is a K-type main-sequence star (K2V) based on stellar classification and it is, among other K-types, informally designated as an orange dwarf, especially by the Otherworlder races. It formed approximately 500 billion years ago from the supernova triggered by the red giant that would later be known as the Solstar. Chemically, about three quarters of the star's mass consists of helium, whereas the rest is mostly hydrogen, due to Etharius being a K-type, which is hydrogen burning. There are also much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.

The diameter of Etharius is about 129 times that of Pemia, and it has a mass about 290,000 times that of Navagar, accounting for about 97.86% of the total mass of the solar system.
