The Perilous Quest to Save Vinyl From Certain Demise

You enter the doorway to the east, revealing a long, narrow hall. The walls are lined with symbols and characters that look a bit similar to the language you know and understand, but you can't make out a bit of what it might mean. Then again, you haven't been able to translate any of the script you've already seen, so this isn't really much new.

The entire hallway seems to be safe and free of traps as far as you know, so you walk along it until you reach a room on the other side.

The room is about the same size as the entrance that you just came from, and there is another doorway to the north. Solid walls block off the southern and eastern sides of the room.

Against the eastern wall, there is a small shelf jutting out from the wall, too high for you to see what might be on it.

What will you do?

Investigate the shelf.

Go north.

Go back to the west.
