Nocturne did not take his introduction to this world kindly. He slaughtered everything he could find before summoners were able to magically confine him. After a period of intense study, League experts divined that Nocturne hunted summoners in their sleep, attacking them in a place where their magic was useless. This seemed to be his only purpose. The families of the victims demanded justice, but League officials were concerned that death might only return Nocturne to the place from which he came. They bound him to a nexus fragment, trapping him in the physical world. As punishment for his crimes, they allowed summoners to call upon Nocturne in League matches, bending his will to the summoners he hates and creating his own personal nightmare. League scholars don’t know whether he truly came from the plane of dreams, or whether there are any more like him. Some theorize that the summoning act affected the summoners' subconscious minds, luring Nocturne to them in their sleep. Perhaps the most disturbing theory is that Nocturne is a person’s nightmare come to life. If this is true, they wonder, who is the dreamer?
