The book was equal parts fascinating and horrifying. A text written by the Pony of Shadows himself, yet somehow permitted onto shelves outside dear old Miskatrotic. I devoured it in a night, taking in the quest for heroes to vanquish the insidious sirens, the assembled heroes gradually shifting their attention and respect to Star Swirl the Bearded rather than Stygian, the desperate attempt to stand with his allies that backfired so disastrously.
