Pastlives
their past lives is interesting but it sounds like it would be really depressing and we know how it ends with them killing themselves. A world like that would make for a interesting story. Espers have a intriguing power setup. I would instead build up ideas and save them for a future original story while using this story to improve your writing. though if you write a original story I would avoid posting it on this site but instead on scribblehub or royalroad.
