Aldo (アルド, Arudo?) is a non-player character in Final Fantasy XI, a recurring figure in Rise of the Zilart and Chains of Promathia missions, and arguably the main character in the Final Fantasy XI: A Crystalline Prophecy - Ode of Life Bestowing missions.
Aldo is the head of the Tenshodo in Jeuno. He appears frequently in storylines which also involve the Archduke of Jeuno because he is suspicious of the Archduke, especially after Verena, his sister, disappears. He appears in Chains of Promathia to aid Prishe after she is stranded far from Tavnazia by a Battle Airship.
Though he and Prishe have no prior association, Prishe demands his help in the name of his dead father - whose help in returning her home she had originally hoped to secure. He also appears in the opening FMV of the game as a child escaping from Tavnazia during the Beastman attack. While his sister is unable to escape with him during the opening cinematic, she is later found to be living in Selbina, albeit suffering from amnesia.
