"Try not to get lockjaw" had me sent, lol. And that opening page on lockjaw gave serious Borg-ian vibes.
A treat of a dungeon, it's silly concept opens up into a genuinely dangerous and short crawl. Quick to read, easy to implement, and an obvious way to introduce a magic sword (or two) into a Cairn game. I look forward to trying this at the table (hopefully soon)
