Dominating the center of the Dueling Theatre is a large glass dome, inside of which lies the main dueling piste, the field where duelists go head to head for the entertainment of the masses. The glass is designed to be one-way, so that the crowd can see in, but the duellists' side is left foggy and opaque to prevent distraction and interference. Depending on the type of match, the field will either be left bare or filled with various obstacles like magical plants and steep rubble. Large sets of collapsible bleachers surround the dome, which when folded serve as smaller pistes for practice. Four small antechambers serve as locker rooms for each team, each denoted by their house's sigil carved into the door.
