Nightmare Human Form

Of the three cursed Gods, Sidus the god that represented the chaos in the world was the only one the three goddesses were unable to seal away. he was also known as the nightmare of the world as he can take control of the minds of the weak hearted people through the fears in their dreams. A shape shifter he often takes the form of a shadowy human, a dragon and a frightening knight. because he was able to materialize from any person's nightmares no one, no matter what they tried no one was able to contain his form to seal him away. The goddess Moiria that represented free will drew him away from the world and fought him on the surface of the moon over the course of a millennium both weakened from the battle they fell to opposite ends of the moon and fell into a dormant state. Sidus awakened once more still very weak his shadowy form eclipsed the sky as he fell back down unto the world spreading his madness  freely, his weakend state left him to take the body of a mortal as his vessel until he could feed upon more fears in the world. with his two brothers sealed away he took reign as the only evil in the world with no desire to free his brothers. This changed when Cerin the cursed god of darkness was able to free his mind into the body of a child. fearing his older brother's power Sidus tries to reseal his brother back into the dark forests.
