As the Dean appeared in his office...which wasn't really an office but an entire realm on it's own that was even bigger that the secret realm the students had to survive for twenty four hours.
To fit such expansive space into a small sized office space like another layer of space is something only those at the peak of the world and having heaven defying space element talent and control could create.
The Dean's fake office was the ordinary room that looked no different than that of an office worker but with bigger space.
The real office is the realm which he always stays in which only a permitted few could step into at any time without permission.
Even while still being in his real office (the secret realm) he could still see and hear everything happening within the Academic domain if he sole wanted.
The Dean sat on a seat as his tapped the armrest in thought rhythmically.
A magic Dragon then?
