Aldo is the most powerful of The Ancient Ones, acting as their leader. He's also the only one who takes a male form when interacting with others, even though "he" is an abstract being. He's the one who makes the more important decisions, and was the one who decided to grant The Revolutionaries a part of their magic, which is now known as Twilight Magic. The other two Ancient Ones fully obey him, and would never act if he forbade them to do so, though both Agatha and Aurea make decisions without asking Aldo's opinion.
