The first age of my project is about old kingdoms falling and new rising, it ends with vindigo crysis and starts about century before.  
Zebras occupy eastern part of the Old World because of savannah on the Cutiemap at the west from Equestria and, well “Fallout: Equestria” where they are used as China. They are rather unstable feudal empire where small tribes live by the old ways under protection of mighty kings who have actual armies.
 
To ride on a rhino into the battle is considered suicide among zebras. So only the strongest of the sacrificial warriors dare to do it and so earn the glory they seek.
 
P.S. As the previous picture got surprisingly much negative, I beg you to explain what is so wrong with this one if it will follow that way.
 
P.P.S. WITNESS MEEE!!!
