On his 13th birthday Damian is sent a package by his grandfather Ra's al Ghul, which contains a dead robin. After a meeting with his mother Talia, he discovers that it is a warning from his cousin Mara al Ghul, who has chosen him as her prey as part of an initiation ritual that she must undertake in order to properly join the League of Assassins. Mara has been made leader of a group known as the Demon's Fist, which was originally supposed to be led by Damian, but became hers when he chose to leave the League.
