Burning with Optimism's Flames (in-universe)

Burning with Optimism's Flames was a book which existed as a work of fiction in the 10,000 Dawns, as part of a series of such books dealing with the war. A stash of these books, together with the Book of Books, crashed on the Earth of the War in the 18th century, and were unearthed in the early 21st century. Various war powers, as well as agents from other realities, became interested in them. However, thanks to the efforts of Rachel Edwards, none of them were able to acquire the books, which became contaminated with Strid biomass and had to be hidden away. (PROSE: Rachel Survived)
