The color of the runes is pale gold, slowly circulating in the dim space, each flicker accompanied by a slight spatial fluctuation, like something repeatedly confirming whether the coordinates here are safe.
There are no windows around the hall, only a heavy metal door, also engraved with runes, with several fist-sized crystal stones embedded at the edges. The stones rotate slowly, emitting a pale blue light.
This is the safe house for the teleportation array. Every teleportation array leading to the Wizard Plane is built in such reinforced underground rooms.
Not just to protect the safety of the users, but to protect the teleportation array itself.
If the enemy somehow reverse-tracks the coordinates of the teleportation array, the multiple defenses of this room will immediately sever the connection between the teleportation array and the Wizard Plane and instantly trigger the self-destruct of the magic array, leaving no usable information for the enemy.
