From publisher blurb:
There are things that dwell in the Crypt, and some are Best Left Buried
Best Left Buried is a fantasy horror game where the monsters are scary and the players are scared. Within the Crypt, these adventurers will be beset by strange monsters, bizarre environments and eldritch magics, which will take them on their journey from fresh faced recruits to grizzled survivors.
This is a book for the Doomsayer. Within its 80 pages, it contains lots of advice of creating dungeons, running games and telling stories. We’ve also added a sample adventure, Lord Edmund’s Barrow, some background about the canonical setting for Best Left Buried, The Thirteen Duchies of Lendal, and rules on treasure, experience and magic items.
While the Doomsayer's Guide To Horror contains a huge amount of material for the aspiring Doomsayer, this book won't make too much sense to you unless you own a copy of the Cryptdigger's Guide to Survival.
