The most striking feature of Tanta Prav's castle is the great sphere of water that hovers imposingly above the courtroom situated on its rooftop. Within it lies the special chamber of uses to conduct the trial by water, a ceremony in which criminals pronounce guilty must attempt to prove their innocence. While the building itself may appear untouched by the events of recent years, the corpses that line the corridors—the remains of unlucky souls the mad Tanta tortured to death—tell a different story.
