Scythe (1)

Back in the outside world, more than a day had already passed since Ashton was headed to clear the second trial. Since then, there had been no news about him. As a result, the management thought it was another loss and was about to mark him as MIA (missing in action).

Technically, he was assumed as KIA (Killed in action), but since no one would be able to recover his corpse from the trial zone, they could only mark him as MIA. This was a common occurrence on Euphoria. People who got tough trials assumed they would be able to complete them and boldly head in. Only to find despair on the other side as they either died or went missing. 

Simply because someone gets a trial, it doesn't mean they'll be able to clear it. Getting a tough trial only signifies that they had the potential of completing it. Whether it would take one attempt or hundreds depended on the examinee of the trial.
