The first two were from the Evergreen Guild that went to two different locations in the western continent. One of them was led to an area controlled by a demigod that can actually shift the earth with her ability. She created a powerful maze that trapped anyone that went inside of it without her permission.
Only one of them was able to get out as they planned out who needed to be ejected. The ones that were left had to hide inside the maze so that they would not be caught by the monsters inside. The return scrolls that Adrian gave them did not work inside the maze as well as if something was blocking them.
"It seems that the demigod is using my Sun Stone in manipulating the rules of space inside the maze. If she could do that then that Sun Stone must have been supercharged and is one of the early ones that I have created." The Sun God Ra stated as he listened in on the request.
