Vasilore was born between light and darkness. This left him uncertain, as he did not feel a sense of belonging on either side. While other Gods shaped better ways of life for people, Vasilore felt lost, empty, and incomplete. He tried to be a great God just like the many before him, but his genuine and kind gestures were often dismissed. It was then that he wanted revenge on humans, something sinister that would make them regret being human.
He noticed people became attentive when they were unsettled. Thus, Vasilore embraced trickery and was sinister. He learned how to separate shadows from their human and helped them create their own sinister identity known as Sombrasos.
