The Dragon King's Human Mate
It was an entire chapter.
Or rather — it had been an entire chapter. In a volume of pre-covenant history, slim and old enough that the spine had partially separated from the pages, I found a chapter whose title had been carefully, deliberately removed — the top of the page cut away with something sharp, the chapter number scratched out with ink so heavy it had bled through to the page below. The text of the chapter itself was gone — not cut out but removed at the binding, the pages taken cleanly from the book, leaving only the faint ghost of them where the paper had pressed against the pages on either side for long enough to leave traces.
Someone had removed this chapter.
