Physiology
Based on the movie, the Solatians can appear to be white-skinned humanoids, though their true forms are beings of pure light. They are capable of extracting pure Core from asteroids, though the extraction process diminishes them, reducing their lifespan, which is hundreds if not thousands of years long.
History
The Solatians were the first beings to appear in the universe an event they called the First Light or what is commonly called the Big Bang. They coexisted alongside another race called Draykanians, a race of pure darkness. Both dwelled within a dimension outside the confines of the material universe, and though both species were diametric of one another, an eternal stalemate lasted for eons between the races.
When the jumpgates were created by an unknown race they accidentally stumbled onto the realm of the two ancient species. The Draykanians seeing a chance to shift the cosmic balance in their favor, tried to invade the material universe. The builders sensing their error closed the gate, but not before one Draykanian escape. To maintain balance one Solatian was sent outside. The jumpgate connecting to the celestial realm was lost creating the legend of the Lost Jumpgate.
Culture
The Solatians were a benevolent species, believing in order and peace. They believed everything needed to be balanced, and were willing to sacrifice themselves to maintain it.
