Following the post Cororo-Gloya war breakup of the Southern Gloya Federation, Greria found itself in vast economic and political turmoil.  Losing access to a large portion of the previous Federation's resources, the new nation was left scrambling to sustain itself not only financially, but militarily as well.  Meanwhile, up north in the Republic of Bovedo, their nation was hit with a massive wave of refugees fleeing towards a more economically stable nation.  One group in particular, the Bovedan Native Party (unrecognized as a true political party), heavily protested against the relaxed response to the sudden wave of immigration.  This contempt eventually exploded, when a small group of members, led by one Colte the Rabbit, staged a violent protest, targeting suspected refugees; leading to his subsequent arrest and exile.  Displaced and disgraced, Colte eventually found his way into the struggling Grerian Republic, and put his previous political knowledge to use.  Within a few years, he had climbed the political ladder; and convinced the populace that the loss of the war, and breakup of the Federation, was caused by the weakness of non-powered Mobians.  Following his ascent and solidification of power, Greria has found itself slowly stabilizing, but slowly becoming more and more radical, and violent towards those without powers...
