PERPLEX CITY, SEASON ONE
- These are underground passageways which lead under the main buildings of Perplex City Academy
- They provide quick access for students hurrying between classes but are notoriously labyrinthical.
- By tradition, new students are never provided with maps to the corridors but instead are given cryptic clues to work out the key to the corridors' layout.
- With their moving walkways, the corridors can be the quickest way to travel around the Academy, but unless you understand how they link together, you could find yourself traveling in circles.
- Rumours persist that some students have entered the Anaduna Corridors and never returned... their ghosts are said to haunt the halls, still searching for their elusive lecture hall or tutorial room
