The Capital Wasteland, A harsh place where only the strong survive, or at least it was until 2277 when Jade 'The Lone Wanderer' Douglas walked out of Vault 101 and removed the threat of the Enclave while looking for her father.
Over the next ten years, she would serve the Brotherhood of Steel till the death of both Elder Lyons and the rise of Elder Maxson where she would leave due to differences.
Now she finds herself in a ruined castle surrounded by horse straight out of a Grognak comic.
