This isnt directly related to Elsewhere U, but imagine a story of a Liminal Space denny’s - where both the Gentry and mortals can go to dine
A dennys on the side of a highway - you can never quite remember which one, but you always find your way to it on the nights when you want to - that’s only open in the evening and night hours, where humans aren’t the only ones who come to dine
A place that, If you try to go during the day, and somehow manage to find your way to it, it’s broken down and abandoned.
A place where you cant see the cooks, and the server’s back is hollow
A place where, If you’re unlucky enough to stay til dawn, you may find that you disappear in the sunlight
A denny’s that bridges the worlds, and serves any hungry soul that comes asking, though whether your soul is being served or fed is up for debate
Crucially, the Denny’s is the only fast food joint inside the rough triangle formed by the two highways and the train tracks that contain Elsewhere U and a good part of the countryside around it. When the sun rises it takes everything in it to…wherever it goes. (Somewhere shimmery, say the people who tried to look through the windows from the parking lot. The ones who were inside never say anything else at all). The change in your pockets turns to wet leaves when the sun rises. But the food is safe, or at least as much as it ever is. And the coffee is very, very strong.
