Collapse of L'embor

Context
Throughout the ages, it has become clear that expanding towards new lands causes instability and unrest. The collapse of L'embor is one of the most accurate examples of this scenario.

L'embor
L'embor was thriving and Its small island was getting overcrowded. So they did the only sane thing, expand. When I say expand I don't mean like an Imperial, I mean expand to unowned islands around L'embor.

The not-so-great expansion
With their great economy, they decided to expand quickly. While expanding they rushed through natives looking like enemies... not just that but they killed a few natives too. The natives, thinking the L'emborians were attacking them, decided to attack back. The L'emborians started to consider these natives as terrorists funded by Robbun.

End... or is it?
Eventually, L'embor fell and broke into many small countries. This was the end. L'embor what was once a thriving community, gone, reduced to rubble. But maybe L'embor could come back with a great world war... who knows?
