Zahara Kingdom!
It was a Human Kingdom that had existed for more than two centuries, decently successful among Human Kingdoms.
Established atop a mountain range, Zahara Kingdom was a hilly civilisation that used the terrain's advantage to forge a future. They were rather successful at that.
The mountain range was rich with resources, with some of them being powerful materials to forge Human Avatars. And despite the deaths they faced from the surrounding Pranic Beast invasions, the Kingdom's population was at a steady incline.
At this rate, as long as they continue developing for a few more centuries, they'll eventually evolve into an Empire. They only had to make decently smart decisions and avoid any drastic setbacks to succeed.
If they played their cards right, they'll survive well past a millennium, the criteria achieved by all major Empires on Sumatra. Until now, they were on the right track. Until now, that is.
