An Interdimensional Hell-Market for Old-School Essentials. Life is cheap here...but a good soul will cost you.

HELLCRAWL is a jumbo sized hexcrawl set in Nethria, the Burning Hell. This infernal module is built for Old-School Essentials and will throw your unfortunate players down into the darkest depths of hell.

This Demonic Adventure for the Old School Essentials system takes a party into a small pocket dimension of the hells. (A little Hellraiser and a bit of Silent Hill thrown into the Slaughterhouse sausage!)

Will you poor souls become heroes, or will all Hell break loose in the final installment of Afterthought Committee's Level-0 series for Old-School Essentials?

100 new monsters. 300 new boons and charms. Absorb the abilities of monsters using harvested components to conduct magical rituals and enchant yourself with boons and charms representing the monsters' unique abilities. Compatible with 5e 2014 and 2024.
