The Anthropophagi of Xambaala is a module for Astonishing Swordsmen & Sorcerers of Hyperborea written by Corey R. Walden and kickstarted by North Wind Adventures along with The Beasts of Kraggoth Manor in the aptly named Beasts and Cannibals campaign. The kickstarter was launched back in March with an estimated delivery date in August. PDFs were delivered to backers on July 30th and the printed books started shipping over Labor Day weekend. I've said before that Jeff Talanian runs an extremely professional and punctual operation and he continues to deliver.
I've had time to read through the adventure and my game group has a few weeks of play in it now, so let's see what this Anthropophagi stuff is all about. Spoiler review after the break.
