Ok so you’ve tunnelled in. You’re sneaking about looking for the exit when you feel a tap on the shoulder. An absolute horrowshow of a human is grinning at you. At least, you think it’s grinning but it’s difficult to tell when it hasn’t got lips. Oh god. It hasn’t got lips. You pass out.
When you come to, you’re surrounded. They are all gesturing at you. The same thing over and over. Your initial terror subsides as you realise they’re not trying to attack, but to communicate.
