Name: Emrakul the Mirror Broken
Aspect: The domains of Emrakul are Darkness, Night and Insanity. He is often associated with the cycles of the moon and the tides. He is a friend of change, be it positive or negative, and an ally of those who would use subterfuge as their main method of operation. Emarkul considers himself beyond the concept of "good" and "evil", and in fact his interest in mortals is only there insofar as they impact the other gods. He is the patron god of those who strive to do the impossible and of assassins and spies everywhere.
Personality: Emrakul is fascinated by the gods, and thus tends to be rather social, if cunning, his plans are complex and what he says is often subject to interpretation. He enjoys seeing how the other gods react to him and will often behave in a way that they find either confusing or distressing, unless he's actually talking about something that concerns him. His personality is subject to random and radical change, sometimes in the same conversation.
Avatar: Emrakul rarely, if ever, manifests to mortals, when he does he prefers the shape of a skeletal figure wrapped in darkness, with the figure itself always being some kind of being that has never existed in this world. To his fellow gods he appears as a cloud of darkness, his true form concealed from their sight,
