Edward Sallow, who would be known as Caesar, was born in 2226. His family once lived near the Boneyard until his father was killed by raiders when he was two years old, forcing his mother and him to flee - eventually finding sanctuary with the Followers of the Apocalypse in 2231. He received a free education from the Followers and eventually became a full member - a scribe specializing in anthropology and linguistics (though he is also well-versed in modern history, as evidenced by his knowledge of the Enclave).
