Fifteen years has passed since the Trevionites invaded the Unicornian planet of Tadna IV, the brutal occupation of the planet forever altered it in every aspect from good to worst. As the forces of Trevion further enroached into the entire Tadna system to seize several more planets from the Unicornians, they carved a swath of mass destruction and committed fearsome atrocities that would forever psychologically scar those handful of ponies who survived and escape the horrors within. When the rest of the Tadna system was swallowed by Trevion, the ghastly forces then mysteriously held their ground against the Unicorns' borders.
Behind the painfully visible death and despair within the once-beautiful Tadna planetary system not only lies the apparent new territories of the rapidly-expanding Trevion Empire, but a complex system of experiments and atrocities including a mass import of non-human slaves from civilizations conquered by Trevion.
The Binarian Empire, Trevion's long-time ally, bribed journalists into their ally's occupied territories to learn of the mechanics behind the horrors, but to no prevail. The planets were rendered nearly unsuitable for non-Trevionian lifeforms, as the desolated landscapes were known as the "Bonelands" for its death, impenetrable darkness, volcanic ash, tainted mana, and spirits bounded within the lands screaming to be freed from their eternal torture by Trevion's beasts inside the Void World; all decorated by the bony corpses of unfortunate creatures that succumbed to the toxicity of the planets. Trevion's goals are not clear though those who managed to escape the planet describe the cities as anachronistic, constructed as great monoliths atop a plehtora of equine bones, inculcating a natural sense of hopelessness and weariness upon first sight. The grim details included mutant anamolies and cybernetic enhancements among slaves, even foreign power generators which contained limbless figures of the unfortunate ponies, billowing a strange red steam that powered the Trevionites' many military bases.
The Ozzalonians on the other hand, are the engineers to the machinery that fueled Trevion's murderous ambitions and are the creators of an effective anti-pegasus flak cannon. Otherwise, they are orchestrating sociological experiments upon the enslaved ponies to challenge their herd mentality and develop new methods of political multi-species propaganda.
The intergalactic community has yet to militarily oppose The Trevionian's intentions, fearing that attempting to claim the planets in their current state would be a phyrric victory at best. Would anyone stand up against these cretins? Or will the ancient evil rise above the soon-to-be ashes of civilization?
The Tadna system: All planets are entirely worn with volcanic rock and darkness, so there's no worrying about diverse ecosystems. They are inhabited with mainly unicorns and moth ponies.
Tadna 1-5 bearing four moons each.
Tadna 6a-d
Tadna 7a
Tadna VIII - no moons, though it does have an unnamed irregular shaped astroid lingering in it's orbit.
Tadna IX - The biggest and most populated planet holding 15 moons.
OOC: Names with a letter at the end indicate moons of planets with their respective numbers, though Tadna six and seven have been annihilated by the Ozzalonian capital ship, Funky President, which still lingers about the system. We have permission from Princess Platinum to include details of her canon and to claim the rest of Tadna.
