The King in Yellow
God of decadence, disorder, and nihilism
As with many of the Great Old Ones, Hastur is imprisoned on a distant world. Yet unlike most of the imprisoned Great Old Ones, Hastur can manifest an avatar on other worlds as long as the light from the strange star in the sky of his prison world shines upon the targeted portion of the second world. He requires the assistance of powerful magic in order to manifest this avatar, known as the King in Yellow, but such magic need not be consciously wrought.
