First University has four colleges and four research institutes.
These eight institutions are located in various corners of Buji Island, hidden and interlocked in such a way that they form a huge Protect Legal Formation. What connects them are the corridors of various shapes and designs.
However, most of the time, students of First University do not choose to walk through these corridors when visiting other colleges or research institutes. Not only because they are winding and lengthy but also because hunting teams often train there. A slight carelessness, and an ordinary passerby could become entangled in trouble.
Aside from school-hosted activities like hunts, which require corridors to accommodate large-scale traffic flow, these passageways are seldom used on regular days.
More importantly, there are other channels for students to travel between different colleges.
Such as the Nameless passages hidden in every corner of the school, or those 'gates' located in the First Hall.
