Look around

The light is dim and the other lockers are all, well, locked, but you manage to peek in. Unfortunately, servitors 1 to 5 aren't human; they aren't, so far as you can tell, alive. Just machines of various shapes and sizes, designed to do manual work. You can't get at the locks to **** the lockers open, and none of the other servitors respond to your voice.

The door to the room is also definitely locked. It's sealed well enough that no light and very little sound from outside gets in. The only thing accessible to you is your own locker, locker #5.
