Master Entity

The Master Entity is the avatar of the Druthulidi Majora.

Description
Believed to be the ancient legend and dark god Majora itself, the Master Entity may appear when the followers of the Goddesses are besting the spawn of Majora. A massive monstrosity of tentacles and arms, Majora's massive form can crush entire armies by simply moving over them. When forces prove resistant, Majora can also unleash streams of unholy fire upon the masses. There are very few who can withstand the might and horror of Majora once a Master Entity has been summoned.
