The War of the Plutonidians

The Plutonidians were a really curious species. They came from nomadic intergalactic populations settling uninhabited new planets, rather than living together with different species in the most attractive and famous worlds of which there were so many within the Mother Galaxy.
A new world was discovered almost by chance. It was a little planet almost hidden by the tenuous reflected nebula of Doga. Now, wars between Plutonidians were only ancient myths... but since the new settlement in this new world something happened and so chaos became order, noise became silence and peace....war!
