From publisher blurb:
WELCOME TO HELL!
Dark Fantasy Settings is a collection of tables and short essays to inspire the creation of grim settings. It includes tables to create your own settings (as well as factions and vistas within the setting) and a few settign ideas. You can also use this book to generate settings for stories, comic books, etc.
The focus is on dark fantasy tropes: flawed heroes, terrible villains, corrupting magic, ominous ruins and damned wastelands.
This is mostly a system-less book, to be used with any game of your choice, but some parts are written with the most popular RPGs in mind (you know, six abilities, hit points, saving throws, etc). It is especially suited for medieval dark fantasy games, such as my own (Dark Fantasy Basic).
