What is the Adjudicator, and how does she fit into the John Wick storyline?

The Adjudicator is a character in the John Wick film series, played by actress Asia Kate Dillon. She is a member of the High Table, which is the council that governs the world of assassins in the John Wick universe. The Adjudicator is responsible for enforcing the rules of the High Table and maintaining order among the various factions of assassins.

In John Wick: Chapter 3 - Parabellum, the Adjudicator is sent to New York City to punish John Wick for killing a member of the High Table on Continental Hotel grounds. She enlists the help of Zero, an assassin and fan of John Wick, to track him down. Along the way, the Adjudicator meets with various characters from the previous films, such as Winston, the manager of the Continental Hotel, and the Bowery King, a crime lord who operates below the High Table's radar.

The Adjudicator's role in the John Wick storyline is significant as she represents the power of the High Table and the consequences that John Wick faces for his actions. Her appearance in John Wick: Chapter 3 - Parabellum sets up the events of the subsequent film, John Wick: Chapter 4, in which John Wick and his allies must face the consequences of their actions against the High Table.
