Vault Dweller's memoirs

The Vault Dweller's Memoirs are the introduction of the Fallout 2 manual. Written by the Vault Dweller himself, they are an account of his history ever since he left Vault 13, up until he founded Arroyo. As it stands, it is the only information about the canonical outcome of Fallout outside a few references in the sequels themselves.
