The Circus of Doctor Trundles was a circus, run by Dr. Trundles and Tanaroo Quinson, which traveled Impiltur and Damara with a collection of monsters. Whenever the circus went through the town of Valls, there was always excitement (which became rare in the time of 1357 DR). The parade often started on noon. Each creature was set in a cage of imprisonment, which neutralized any magical abilities from the creatures within. The magic does not, however, inhibit the physical strength of the creatures.
