There was a stone statue in the Little Palaces courtyard that had stayed exactly where it was for an age and a half. No one knows where it comes from, who it depicts, how it came to be, only that it is known as the Hallow. Then Alina Starkov begins to visit it, and something thought long lost returns. Alina/Fem!Harry/Darkling. Triad Pairing.
Inej returns to Ketterdam, unable to say no to Alina about traveling together. Within days, the Menagerie burns to the ground.
