From the publisher's website:
This stand-alone adventure is designed for a single player with no GM and basic rules. All you need to play is some dice (d6, d8, and 20), a pencil, some paper, and this book.
The rules are explained as you play. Begin at paragraph 1 and proceed from there, taking notes as you go. As the dwarf hero Kalgor Bloodhammer, you'll use all your might and cunning to protect your home from an invasion of hungry undead.
Kalgor Bloodhammer and the Ghouls Through the Breach includes both a 1st level and 3rd level character sheet for Kalgor, fully compatible for use with any beginning party to continue your Pathfinder RPG adventures!
