No Second Chances

Ceni was already speaking in almost a hushed whisper but Henrik still took a quick look around to make sure no one was eavesdropping when she brought up teleportation. He snapped his fingers and a flimsy light golden barrier with various elegant designs erupted around them.

"Please keep your voice down! And...yes. I have already tried it," he cautiously reached out into his inner shirt pocket and pulled out a small stone token that was broken in two. This was his identity token.

Every single student that was participating in the examination regardless of their affiliation to the three powers was given an identity token.

Other than a way to keep track of the examinees and as an observational device, perhaps the most important function of the token was to forcefully teleport out any student back to the ship assuming, of course, that they managed to break it in time.
