It would appear that the MASTER's TELEPORTATION PAD is not on its POWER FONT (circle on the floor), as the sigil in their alcove is not lit up.
The APPRENTICE has never seen the MASTER's room. They assume it is full of cool things and is very nice to look at and observe.
Or it could be bare and empty. Wouldn't that be funny?
Or it could be somewhere in between.
Now the APPRENTICE doesn't know what to expect.
