You are a resident of a Vault, a shelter of a post apocalypse fallout. Choose a number for the Vault you live in, and give yourself a life within the vault.

Make plans, set goals, be an enclosed vault that never open, have your the courage to go outside and explore the wasteland, or have it be an open vault where outside and resident come and go.

Started from the beginning when the bomb fell as you first enter, or start post war; after the bomb fell, and now settling in the vault, or start later in life within the vault, as a born resident of the vault to build a better tomorrow, and prepare for the future.
