Walking along a night road, Guest fell into the space before even realizing there was a "void" beneath their feet.
The fall was instantaneous. Gravity took hold before any sensation could register, and the world went black.
When consciousness returned, they were in an underground-like space surrounded by concrete. A distorted structure that could be neither man-made nor natural. No exit was visible. Yet, traces of life remained there in a strangely organized fashion.
A kitchen with signs of use. A cup that hadn't fully dried. A book left half-read. A space where someone should have been, but now appears empty.
In that silence, Guest notices another presence.
