In the 1011th Year of Magnapur, four rebellious slaves successfully infiltrated Lord Lust's party in Magnapur to burn the Book of Names, featured in the first chapter of Slaves of Magnapur.
The Book of Names was a widely rumoured artefact of the Magnapuri Empire created by Magnus the Binder. It was rumoured to be the source of the High Elve's control over the Elfborn - a book containing the name of every slave born in the Empire. Lord Lust's personal Timekeeper (generally referred to as "the Timekeeper") Punak Chambaya discovered this book was real when his master was tasked with protecting it for his niece Magna the Scholar.
Punak Chambaya was a member of a rebel cell alongside Adhina, Tomothy and Grin, collectively referred to as The Bookburners. The four of them infiltrated Lord Lust's party as slaves - Chambaya as Lust's Timekeeper, Adhina as a performer and pleasure slave, and the two dwarves as barrel carriers. Adhina entertained and attracted Lust, who arranged to "purchase" them via Punak and take them back to his chambers.
In Lust's chambers, Lust was interrupted by Punak before he had time to visit unpleasantness upon Adhina. Grin and Tom had brought the goose upstairs early, and Lust insisted on returning the party to cut it, allowing Adhina to pocket the keys to the location of the Book, hidden in Lust's secret vivisection chamber.
The Bookburners got into the location of the Book, fighting through a group of Broken Men, a selection of traps, and a guard addahva. They retrieved the Book, but set off an alarm and were discovered by Lust and his guards. Adhina attempted to read the Book, but was caught in an aging curse and only rapid intervention stopped them from turning to dust.
Punak's name was known by Lust and he manipulated ambiguous wording to slit his own throat to avoid giving up information. Grin grabbed the book and ran, before Adhina took it off him to attempt to make a getaway. Adhina was badly wounded, but Tomothy stalled Lust long enough for Grin to rescue them, burning the book with a tinderbox there and then to avoid it falling back into enemy hands. Lust killed Tomothy but was badly injured in the process. Grin escaped with Adhina, narrowly avoiding more Broken Men.
