Snow King

The most evil being on Endor is the Snow King, a diabolical being of immense POWAH. He is powerful that he held off Simon the killer Ewok and barely had to lift a finger. He controls the seasons and the weather in general on Endor and whenever he feels like it, he throws a snowstorm onto the Ewoks who view him as an immortal god. When the Empire set up their bunker there, they payed him off to leave them alone. After the end of the battle, the rebels did the same. The Ewoks never caught wind of this however and still had to suffer his evil for many more years to come.
