Pre Equestria war fiction Idea suggester needed

Hello,Everypony. I need somepony who could make my idea better as they're idealist wit me.My story is about the boy who accidentally took himself into the war of the ten races before Equestria was formed,even before hearth warming eve,

The war was blood bloody and chaotic There was a forecasting by every great predictors of each kingdom about "eleventh race"who will come and end everything.

The kingdoms are included Earth of earth ponies,Pegasopolis of pegasi,Unicornia of Unicorns,Griffonia of griffons,Mines(Mi-Nes)of minotaurs,Tabelon of goats,Que of kirins,Greenglass or deers,Pawius of wolves and Zimtan of Zebras.They were fighting each other and tried to find the object called "the tiara of the power"that known as giving the owner eternal endless power.

i hope anypony who see this wills end me hooves
