Its native species is (unsurprisingly) the Elonians though befitting its status as the capital world of a space faring alliance, it boasts many non-native immigrants of various species.
Long ago, a mysterious extraterrestrial ore crash landed on Elonia. Continental shifting however buried the ore deep below the surface.
In time, the Elonians colonized their world and formed the Solstar Order. The planet was protected by an impenetrable laser grid and several space based weapons from orbit. Such was the strength of these defences that none of the inhabitants felt threatened by alien powers. On the surface, farming techniques had advanced to the point that they essentially eliminated scarcity and, as a result, crime became almost non-existent.
Then it all went to hell when the Dire Wraiths broke though the defence net (rather easily) and invaded the planet for the ore. The subsequent fighting all but destroyed Elonia despite the Knights being successful in expelling the Wraiths from the planet. Later Rom would reflect that the "ultimate victory" over the Wraiths was as bitter as any defeat owing to the resulting state of the planet.
Space Knights often swore by the landmarks/gods of Elonia.
After meeting Darby Mason and taking refuge in Blind-Eye Cave, Rom told her his backstory on Elonia and mournfully reflected on the lost beauty and serenity of his homeworld and how the Space Knights had largely failed in protecting it and other worlds under the protection of the Solstar Order as well as noting how very far it was from Earth.
