Final Fantasy IX
Vivi is a young Black Mage, who was first seen in Alexandria, trying to sneak into the play ‘I Want To Be Your Canary’. He managed to sneak in and see most of the play, but was eventually seen and chased by guards. Vivi ended up getting mixed in with a bunch of kidnappers and aided them in their escape with the Princess of Alexandria. Itisi revealed that the Princess wanted to go with them to seek help from her uncle and that it was her uncle who had hired the kidnappers in the first place.
Vivi discovered that Alexandria produced Black Mages that look a lot like him. However, while most of them were mindless a few had “awoke” and went to create their own peaceful village. There Vivi found that the Black Mages at a certain point will die. He started to wonder if he would die too.
