Concept: “When Lorenz Hattendorf was murdered, one member of his party managed to escape. […] she knows where the man’s magic sword fell when he was torn limb from limb.”
Content: A seemingly unassuming tower crawl with a murderous climax (and some loot along the way)
Writing: Mostly devoted to background and description but includes stats for enemies and the titular sword (which is pretty brutal even while broken)
Art/design: Graphics add character and ambience, and the maps provide easy navigation for the GM
Usability: It’s a tower. There’s nowhere to go but up.
