The western bloc of Moridia knew that they didn't have much time to find a permanent solution to the Evolutionary Army before the next generation of evolved evosapiens in the Evolutionary Army of Eat Moridia effortlessly crushed them.
Not a single one of them could even conceive of how they could possibly overcome the Evolutionary Army once they got their hands on such power.
Thus, if they had to act, it had to be quick.
Human civilization, having successfully defeated the evolutionaries, proved to be an entity that West Moridia could look up to.
It was considered taboo in the world to actively conspire against kin of your species with those of other species, but the Western Bloc of Moridia had grown so sick of the Evolutionary Army that they no longer cared to be dubbed as 'race traitors.'
