The Circus Arcanus is a travelling circus which displays human oddities. The owner of the circus is a wizard named Skender. The Circus visited New York City at the beginning of December 1926, which coincided with Newt Scamander and Aurors from MACUSA capturing Gellert Grindelwald. In fact, Graves is seen looking at a poster for the Circus Arcanus while walking the New York streets (WFT).
The Circus Arcanus was scheduled to travel next to Europe.
