The Court of Owls! Perhaps you've heard of them! They're a shadowy organization that has worked behind the scenes of Gotham for quite some time. Even the crazy 1970s! When everyone was listening to disco and snorting cocaine, or whatever people did in the 70s, the Court of Owls were merking fools left and right! Even teaching their victim's children their signature rhyme, to announce their revival. Elite level trolling!
Flash forward to now, and once again, Gotham is in chaos, yadda yadd, Forever Evil, and a high ranking member of the Court (maybe John Wycliffe, the current grandmaster) watches the chaos from above, with his daughter. As the two descend deeper into the secret areas of their grand building, the man tells his daughter stories of the Court, who they are, and what they are to Gotham.
The stories told of the Court include them threatening the mayor of Gotham in the early 1910s to not allow the unions in the city, only to kill the mayor later in their maze, with a Talon that looks a lot like William Cobb (but 1914 may be too early for him, I think). Back in 1891, a young photographer with evidence of the Court bids his wife farewell, as he decides to temporarily flee to Philadelphia, only to be hung at the train station, and his wife later found dead. The Court would then frame it as a murder/suicide. Then finally, we see Felix Harmon in his prime, and his prime is recklessly killing anyone he wanted, and drawing too much attention towards the Court.
As the father and his daughter find themselves deep underground in the tombs of the Court, it seems the father has a plan to help them take back the city, only for another member of the Court to appear from the shadows, crossbow in hand. This women tells the man that she knew once the riots started, she'd need to guard this particular tomb to keep the Court from making a terrible mistake. But before the woman can fire her crossbow, the man's daughter surprises her with a knife to the neck.
With the temporary setback dealt with, the man and his daughter approach a grand tomb, which belongs to the first Talon ever used by the Court of Owls, who is soon to be woken up.
