security checks of the academy

Exiting the portal, Rio stepped onto the ground, Amelia following suit. He surveyed his surroundings and noticed a steady stream of people emerging from the similar magic portals nearby. 

The current location they were in was an open expanse within the branch of the World Association. The direct teleportation to the academies was barred due to spatial magic limitations enforced by the protective barriers surrounding the academies. This was why branches of the World Association were established on each floating island. All transportation and teleportation converged at these branches, subjecting individuals to thorough inspections and registrations before they could proceed to the academies.

The portals nearby were opening and closing on a regular basis. As once someone used a portal and stepped out, a staff member would come forward to take them away for the security check and their registration. No matter the status, everyone had to go through this process.
