My story is set in the future and in my story there are going to be Eternals. Eternals are the same as humans but they are immortal. The Eternals have a council and the council have a police force called Chasers, who do the councils dirty work. The council are scared that if humans find out about them, then they might try and get immortality themselves. There are going to be Outlaw Eternals that think they are superior to humans because of their immortality and go on killing sprees. Are these good ideas? Does anyone had any other ideas for my story?
