Things done in the name of research... Walking the Underworld, taking pictures. Mixing drinks, testing recipes. Wandering through the lists, wandering through the fields. Starting a game in one world, ending it in another still. Place everyone in a room and just see what they do. Let's get out of here.

Officially, this machine doesn't exist, you didn't get it from me, and I don't know you. Make sure it doesn't leave the building.
