Subtitle: A Black Grimoire for the Hyborian Age of Robert E. Howard
from the Introduction:
Welcome to Age of Conan: Secrets of Acheron. This book is a follow-up to the first Age of Conan "hack" for the original edition of Dungeons & Dragons. It is commonly thought that the Hyborian Age of Robert E. Howard is a "low fantasy" or "low magic" setting. This is patently untrue. Magic is part and parcel of the Hyborian Age, and it is everywhere. It just takes a very different form than that in what might be called "vanilla" or "bog standard" D&D games.
Magic in the Hyborian Age is alien, unnatural, and corrupting. It can be helpful, but is far more often harmful and inimical to human life. It comes from the Outer Dark, the home of the Nameless Old Ones who ruled the world thousands of years ago, before even the sorcerer-kings of Acheron held sway over the Hyborian peoples.
This book, then, is all about magic in the Hyborian Age. In it you will find new spells, new takes and tweaks on the sorcerer class, and information on books of magic and artifacts, and even a few magic items to boot.
A sequel to the Age of Conan campaign notebook. This sourcebook/guide adds information on magic for a Hyborian Age campaign using the original D&D rules.
