Obsidian Vault – Hardcover Campaign Book

Explore the Ancient Bones of a Sunken Empire

Imagine two great empires locked in a cold war of magical weapon stockpiles and espionage.
What happens to those stockpiles of horrific silos once their creators’ civilizations crumble?

They leak. Much like radiation, infecting the island to which the stockpile is linked.

A thrilling and original 5e campaign setting of expeditions into unknown horrors buried beneath
an ancient advanced civilization, The Obsidian Vault begins and ends on one island.
This allows GMs to drop it into any world, be it homebrew or established.
