By Thy Sword

The story of five cousins who loved and lost, and like the Phoenix rose from the ashes, fierce and terrible, to bring about the end of an era. This is how their bond bent but never broke. (In which Hitsugi can't avoid Fate, Isuke and Nio defy societal norms, Otoya spirals into madness and Tokaku keeps tripping with the same rock.) / Supernatural AU, classic pairings, worldbuilding
