He Never Changes

Rean approached the gate, which had several inscriptions on it. After touching them for a while, he quickly noticed. Those were not inscriptions related to formations. They were just marks carved with not much of a purpose. Nothing but aesthetic work. A small hole went deep inside the gate at the very center. 

"Is this thing a keyhole?" Roan also noticed the hole before asking the others around him.

Rean tried to pic inside the hole with his Divine Sense and Soul Power Scan. Surprisingly, it did go through the hole, even though the material of the wall and gate could block them all. Unfortunately, it reached a small open space just a few centimeters in diameter inside the gate, where he couldn't see anything. "It doesn't seem like a keyhole to me, at least."
