Bloodstone Wars is part 3 in the 4-module Bloodstone Pass Saga. Designed for characters of level 17–20, it places the PCs in the role of rulers of embattled barony, and mixes traditional AD&D adventures with scenarios designed for the Battlesystem miniature rules. The PCs have to deal with mining hazards, transport the bloodstones to market, survive an attack by assassins, wage a war in five separate battles, and hunt down the leader of the assassins in a traditional dungeon crawl.

From the back cover:

What strange role does Orcus, Prince of the Undead, play in the invasion of peace-loving Damara? And what interest does the Grandfather of Assassins have in the tiny barony of Bloodstone Pass?

With this adventure, your player characters inherit an entire barony—with a recently-reopened mine that produces immense wealth. Wealth enough to attract the dangerous attention of their neighbors... wealth enough to attract the attention of the Witch-King of Vaasa... and Orcus himself!

Now, your tiny barony is the pivotal point in a war that threatens to engulf the entire Forgotten Realms. Take command, and defend yourself against the encroachment of the evil, demonic forces of the nightmare realm of Vaasa.

A large, four-color map of the region makes your new realm come alive. Wild and wooly Battlesystem scenarios (with options if you're not into miniatures) give you the full range of battlefield excitement!

Come learn why high-level AD&D game play can be much more than just monster bashing. The Army of Bloodstone pass wants you!
