Find House
You enter the City. It is a gradual process; at some point you find that there is more Civilization around you than not. You stop some People along the way to show them your Pamphlet, with the carefully-lettered Address to the House where you need to be quite soon. It is nearly fully dark. The People give you looks of mild surprise, but point you in the right direction easily enough.
You reach the House in the dark, barely making out its number. The glowing Window on its front is reassuring; unlike all the other glowing Windows, this one is attached to a place where you are supposed to be.
The Door is painted a vivid but worn turquoise, its frame white. Here you are.
