From publisher blurb: Get out of the Vaults! The vault dweller is an iconic character common to most post-apocalyptic worlds. Individuals who wisely anticipated the coming of nuclear Armageddon, vault dwellers bring a unique perspective to the post-apocalyptic world since they have the closest ties with the world before the Fall of mankind. Vaults are isolated communities, frozen at the time of the Fall and left to evolve without the harsh influences of the changing world above. Vault Dwellers is a Darwin’s World campaign starter. It provides a short guide for creating vault dweller characters and a ready-to-use starter adventure that provides an example vault complex and a series of encounters for the initial foray into the Twisted Earth.
