Trouble in Legrion

Iegrion. A semi-temperate desert planet which is home to hundreds of introduced fauna and flora, there are large mountains, jungles, wetlands, dangerous caves filled with dangerous predators, beautiful shores, land reefs, and some places are in utter waste. This world is one that was looking to the future as it's sentient animal inhabitants hoped to build a bright civilization of Teadr 2 technology. Unfortunately, a cristailised meteor, though no bigger then a hover car, crashed into the planet and caused it to rain christailised fire that ruined cities any hope of a civilised world, while also giant ever burning christails grew from the ground, large enough to be forever noticable on the planet with terrorfying burning horn-like grace. Those people are now trapped in a battle to survive, a struggle to decide the fate of the planet. At the center of this fight is the energy substance known as illusium, a precious, rare, and limited resource that was last found in the Core Sector and has existed since the AUU First Cartoonian War, which arrived with the meteor that struck the planet, which can power machines, give magical powers, or re-sculpt life into new, different forms. This being said, while some welcome this subtence, others clearly grown to hate it because of it was from the chrsitailised meteor that ruined their civilisation, as such, they formed a faction to hunt down and destroy every trace of the subtence and try to force feuders to put aside their differences and re-start the lost dreams. However, unreasonable as that sounds, they're more justifived then just being haters of a seemingly useful reshorce, as there was a reason why Illusium is so rare to begin with. It is also highly corruptive and makes those who uses it's powers more and more aggresive and feudulent, only serving to worsen the already ruined world. Thus, this faction, The Legrion Restoration Army, are not as unreasonable as they appear. However, that didn't stop them from dealing with resistence on all fronts, esepically from the LRA's main enemies, The Defenders of Illusium, an ideal sounding group of fighters defending the reshorce from the Army and encouraging communites to continue using the reshorce. However, the defenders are nothing but corrupted addicts of the illusium, as the great burning christails feed on the continuting conflict and slowly turn the planet into a giant christailising planet filled with Illusium, where eventually it'll make another christailised asteriod and eventually the cycle will begin again. Unfortunately, the Christail Defenders earned the sympathies of the Heroes Act because of the LRA being albeit abit to stern about the illusium's existence here. However, the Lougers, thanks to Gazelle, know better and now that just because a group sounded more ideal doesn't mean they're truthfully ideal. But when the HA already made a strike against an LRA based, the group already came to the concludtion that the heroes are against them and made them wanted. Now, it's up to the Lougers and Gazelle to prove to the HA that the Illusium isn't truely worth it and that idealistic looking people doesn't mean they're right for the world. How can our heroes fix a christail-tainted planet?
