While ambling along, cramming a large chilli burger down your throat and reading
a dubious magazine, you trip but somehow miss the ground. You are falling
towards a large neon sign:

'VOID under construction. The management apologises for any reality failures.'

You are rescued, but your burger is incinerated as a public health hazard.

Registration Desk.
You are standing in front of the Void's registration desk, a large green demon
sits here registering all newcomers. The demon hands you a registration form
marked "All Ape Descended Lifeforms" and says "Fill it in!"
