Idly perusing Legends mode for my new 5.10 world, I find that the Vampire Lord Frugoten Specialsoldiers the Decisive Harvester has not only written a 255-page autobiography ("It Must Have Been The Vampire Lord", a title presumably taken from multiple crime reports), but then followed it up three years later with a book about his autobiography (a mere 27 pages, but out now in Dragonscale-bound limited edition). The writing is described as "stunningly self-indulgent".
This contrasts starkly with the autobiographical work of the Minotaur Arsttun Disgustgullies the Patterned Walls, which lasts a mere 22 pages. It's entitled "The Sunken Idleness of the Minotaur", and the writing is generally thought to be rather cruel.
EDIT: Arsttun followed this up with an extended 29-page version several years later, titled "The Unabridged Arsttun". The writing is "as vicious as can be".
Further research reveals that Arsttun was the king of a sizeable civilization of Succubi for 140 years. Although he presided over a period of great expansion and personally led (and won) the defense in every major battle of that period, he spent most of his time writing books. He authored on subjects as diverse as the various forts under his command (Recordings of Scourgescrubbed, year 4; "the writing has a hint of viciousness"), his subjects ("The Succubi, I Wait For Thee", year 31), his own works ("The Book: The Truth", year 37; "the writing is as vicious as can be") and of course himself, culminating in his final work "Arsttun Disgustgullies the Patterned Walls and Arsttun Disgustgullies the Patterned Walls", year 126, a 148-page Moonstone-bound edition in which Arsttun finally comes to terms with his life and... no, wait, it was suffused with "a hint of viciousness" and was the last thing he ever created.
He was slain 14 years later by an uppity fisherdwarf.
