Jacob walked toward the now open door, gesturing for the other students to follow him. "Come on then, we'll show you around. Don't fall behind, and don't wander off. If you get lost, then it might take you a while to figure out how to get back. This school is deceptively difficult to navigate if you don't know your way around." He chuckled.

The charms on the school to keep it hidden were very extensive, and the ease of getting lost was one such perk. If someone didn't know the school at all, it would protect itself, assuming they were not a student, and keep them lost, until a student found them and could either guide them to where they needed to be, or, if they were a threat, wipe their memory and leave them somewhere safe. This was why the initial tour was always so important to the students, and why Jacob had been giving tours for the last 28 years.
