"This is where the training rooms are, we're free to use them whenever. I usually go with this one," Remarked Aria, as she opened one of the doors in the wide corridor she was leading me through, a loud crash echoing out from inside the room.
Oh, looks like it's occupied.
I couldn't hear a thing outside the room, the walls and door must be soundproofed on the inside.
There was a woman inside, swinging a spear around...she looks kinda familiar.
"Hm? Oh, it's you, Ariella. Didn't you see the 'occupied' sign? You know it's dangerous to enter the training rooms if someone's already inside."
"Uh, it said 'vacant' though, you forgot to lock the door," Aria responded in bemusement, before subtly and nervously stepping in front of me.
There's a rectangular holographic display across the outside of the door. I see, when you lock these doors from the inside, this display displays the word 'occupied', and 'vacant' if it's unlocked.
