Ending This Holy Crap

Nabb, An ocean planet which had only 5 islands. While the islands were inhabited by the Aufones, the oceans were inhabited by the planet's main race, Teadr 3 fish beings called Nabbans, which had a 3-year war against the Aufones since they inhabited on what the Nabbans considered holy lands. They eventually settled this dispute through a peace treaty. However, that didn't entirely mean all is settled and done. The Nabbans felt that this is their home and strangers didn't had a right to be a part of it. One day, the Nabban main ruler, King Corron, openly desided to grab the physical peace treaty, and ribbed it to shreads RIGHT IN FRONT of the face of the Aufones' leader, King Hyrule. Hyrule greatly felt insulted that Corron just disrespected his father's work and the war is reignited?! The Grand Council urges for the presence of the lougers and the Heroes Act to resolve this conflict and restore peace. However, during their time their, they discover that the Corrons have a more justly reason for re-launghing the war. King Hyrule is treating the planet extremely poorly. He's turning sacred tree lands into cities and factories, subugating animals considered holy to the Nabbans into pets and test animals, even as food, and worse of all, Hyrule has legalised the slavery of Nabbans that are living in or near the Aufone cities. Natrolly this would easily make the lougers and Heroes Act realise that Hyrule is nothing but an asshole and needs to be rid off, but the problem is, he's the dear brother of a Leagon leader, King Clax Zsaroo, who cause of blinded brotherly love, gave his CLEARLY rottan-ass brother diplomatic ammunity and Leagon protaction, meaning that the HA and Lougers are by law, forced to fight for the Aufone side. How can the lougers be able to proof to Clax that his brother is a total dick-cheese and that the Nabbans are more victims then provokers?
