The dimensional tunnel shattered as the experts shot forward. King Elbas had only reinforced the structure's edges, but that empowerment didn't make it able to endure the immense pressure radiated by the group.
The difference between the void and the area inside the dimensional tunnel became unclear as the experts let the massive acceleration generated by King Elbas' sling lead them forward. The group didn't have to do much in that situation. They only had to make sure not to fall into the blackness.
That also turned out to be easy. King Elbas had studied the entirety of the dimensional tunnel before creating the sling. The item already knew where to send the experts while limiting their chances to fall off the separate space.
The only variable in the process remained the hole in the sky. King Elbas couldn't understand how big that opening was from his previous position, so he had to limit the eventual landing area to a relatively large spot.
