A soldier would enter the room and toss out temporary ID badges to them. "Rise and shine maggots, today is the start of your brutal regiment of training. Three of you line up. You will be immediately escorted to the VR Chamber for lesson one of your brutal combat sessions. We will learn what weapons you posers are capable of wielding and go from there. The rest of you will be doing push ups and sit ups here until I return. Should any of you morons fail to do as you are told, this will be your punishment." The general would push a button and a TV would descend from the ceiling and show a tape of a prisoner being painfully electrocuted.
"Rule 1. All of you maggots are to be in your room by 9 Pm, NST no exceptions."
"Rule 2. No communication outside of this facility, and you are not allowed to teleport out, portal out or do similar."
"Rule 3. All use of abilities must be cleared with the teachers."
"Rule 4. All previous weapons you have on you are now to be handed over. They will be confiscated until later on."
A bin would rise from the ground to hold the weapons.
"Go ahead, put them all in."
