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.
Some ten million years ago, the Titan Emissary, distraught at the death of Prima, fled his people before eventually crashing on prehistoric Elonia. His death was witnessed by a native hunter. 600,000 years prior to the present day, Shockwave fired a sample of Ore-12 at Elonia, the sample unknowingly landing atop Emissary's crash site. Continental shifting however buried the ore deep below the surface.
In time, the Elonians colonized their world and developed a unified world peace prior to their development of interstellar travel. Dire Wraiths in the Elonian star system, the Elonians formed the Solstar Order.After attacks by the
Elonia itself 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 lasted for a month and 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.
After teaming up with the Micronauts, Rom explained the Wraith invasion of Elonia to his new allies.
After the Iron Ring's failed invasion of Cybertron and the magics unleashed by the Visionaries within the planet had roused Unicron into action, he began consuming Cybertronian colonies in preparation for his attack on Cybertron itself. Drawn by the Ore-12, he began devouring Elonia. Though the Cybertronians provided assistance, using space bridge technology to warp 2/3rds of the population to safety, Unicron ultimately consumed the planet drawing on the power within the Ore-12.
