Broadly? His area of specialization is US History. Growing up in Macon, aka the Heart of Georgia, he was kind of surrounded by Civil War history (Macon was the official arsenal of the Confederacy), and he just sort of...took an interest in it. He had a falling out with his parents when he decided to continue studying history and become a professor, because being the older Everett child they had been expecting him to take over managing the pharmacy in their waning years. (In a way, he kind of did, but not in the way any of them had thought or hoped.) He taught at UGA for six years before...events, and in that time he was probably asked to teach a lot of basic, lower-level history classes that were general US History. His own degree is in History with a focus on 19th century America and the American Civil War, and he wrote his doctoral thesis on Macon in the Civil War.
