Offa (died 796) was the King of Mercia, reigning from 757 until his death. His rapid expansion of his territory paved the way for the unification of England, and he was considered the most powerful Anglo-Saxon king before Alfred the Great. Unbeknowst to many, Offa was also a member of the Order of the Ancients.
Offa's membership in the Order was eventually uncovered by Tata, a Palatinus of the Order whose grandfather fought alongside Offa. Tata later learned all he could of Offa and sought to follow in his footsteps.
