You're clairvoyant. You are a dream walker, a rare clairvoyant. You can enter the minds of others and manipulate their dreams. Clairvoyance is hated; feared, so the Scion government does everything they can to hunt down any Clairvoyants in London. You tried to be careful, but one day, you got captured by the scion government and sent to Oxford, a city hidden from the rest of the world, where Rephaim, mysterious, cruel, immortal creatures rule over different kinds of clairvoyants. They feed off of human's Aura. When they do, Rephaim's eyes glow the color of the human's Aura.
