Night of the Owls
"Batman: Night of the Owls" is a comic book crossover storyline published by DC Comics in mid-2012, and featuring the Batman family of characters. Primarily written by Scott Snyder, the arc is the first major crossover storyline of The New 52.
The story pits the Batman and his allies against the Court of Owls organization as they attempt to cement their control over Gotham City, which they have been manipulating in secret for centuries. As described by Nightwing writer Kyle Higgins, the series is the follow up to Batman: Gates of Gotham and divulges more of the history of the city before the turn of the century. The crossover has been described by writer Scott Snyder as the first story arc of a Batman trilogy that he is planning. According to Snyder, in terms of internal chronology, the story arc takes place in a single night within his full Batman arc "The Court of Owls."
The story arc stretches across various comic books, each building the story for the Batman: Night of the Owls by following different Gotham characters as they deal with the onslaught of the Court of Owls. Upon hearing a distress call from Alfred, all the members of the "Bat Family" race to various targets in an attempt to save them from the Court's assassins, the Talons.
In Batman, the Talons descend upon Wayne Manor and infiltrate the Batcave, causing Bruce to defend his home and his base from the intruders before heading into the Court's siege on Gotham. In Detective Comics, Batman quickly makes his way to Arkham Asylum after defending his home to stop the Court from assassinating Jeremiah Arkham. The Nightwing tie-in issues follow Dick Grayson's encounter with the Talons of the Court, and has more meaning since Dick was being groomed as a child to become a Talon himself while a member of Haley's Circus. In the Batman and Robin tie-in issue, Robin is tasked with confronting Talons threatening a high-ranking military General targeted for death by the Court.
