Margaret has described herself multiple times as "One who rules over power," and Theodore describes himself similarly at the start of his Bonus Boss fight. The description of "Power", the persona, states that Powers, the order of angels, are academically driven and are concerned with ideology, philosophy, theology, religion, and documents, explaining their fascination with the real world and the reason they seek the old documents from Tartarus. It is also said they serve as advisers and policy planners and have the duty of overseeing the distribution of power among humankind, so the "One who rules over power" is practically a dead on giveaway.
