Alpha Four, or A4, is an enigmatic figure from the turn of the first millennium. Although the formality of his education is uncertain, we know he studied military history, martial skills, languages, history, philosophy, mathematics, religion, and wrote extensively. Evidence suggests he was a ranking courtier and military advisor in the turbulent environment that was England one thousand years ago. He likely served in Æthelred II’s court (and possibly Sweyn I, the Danish sovereign who briefly sat on the English throne in 1013 C.E.).
