Idea for a fantasy short story
The diary of a foreman running a construction team who a building a temple to an evil god. The eldritch architecture is already really difficult to engineer and the more complete the temple becomes, the more difficult the work is. Men accidentally trigger the traps they have just constructed, keep being snatched away by things, occasionally become possessed and start building incomprehensible shapes. And the Evil God is a literally nightmare client, appearing in the foreman's dreams to complain about the quality of the tiling. Eventually the priests try and stiff him on the bill and he removes the safety capstone, causing the whole thing to be sucked through into a dark dimension, wiped from reality. Unfortunately this means it has also been wiped from his memory when the next bunch of Evil Priests come calling.
