Aro was born in Greece just after 1300 b.c. All his life, he was ambitious; power was always his primary goal. It was in the pursuit of this goal that he was transformed into a vampire in his mid-twenties. During the first century of his vampire life, he joined forces with two other vampires, Marcus and Caius, and transformed two humans into vampires: his sister, Didyme; and his future wife, Sulpicia. Aro formed this coven (which also included Caius’s wife, Athenodora) in order to further his ruling ambition, seeking strength in numbers to augment his own powerful mind-reading talent.
