Eryndor knew he had two layers of protection.
One was the Support Shrine.
He had made countless guesses up until now, and could only conclude that these might be some kind of advanced technology stolen from Cyborgs or might be a Mystical Artifact.
Naturally, he had also once made a guess that these Support Shrines might be an extended, or you could say, an additional feature of the Mystical Artifact which was used to protect the students.
The second layer of protection was naturally that same Mystical Artifact.
Sander had said that if just a disguise could fool the Mystical Artifact, it wouldn't have been used to protect the students.
It meant that the protection based Mystical Artifact was at least somewhat impressive right?
Also, a team from the Human Federation had already scanned this secret realm. If there existed beasts or anomalies which escaped their scanning, they must also be impressive in their own ways right?
