Equip the map in the other room. Then call out towards the North to see if anyone will respond. Then consult the Helix Fossil.

You pull out the map, you can't see anything on it because it's pitch black in here right now. You call out north, but you get no response, or at least, the whispering doesn't seem to change. You do not have a helix fossil and you're pretty sure such a thing isn't in this game. The rat has moved away from your feet. What do you do?
