クライヴ・ロズフィールド, Kuraivu Rozufīrudo

The firstborn son of the Archduke of Rosaria. Though all expected him to inherit the Phoenix's flames and awaken as its Dominant, destiny instead chose his younger brother Joshua to bear this burden. In search of a role of his own, Clive dedicated himself to mastering the blade. His practice pays off when, at just fifteen years of age, he wins the ducal tournament and is dubbed the First Shield of Rosaria—tasked to guard the Phoenix and blessed with the ability to wield a part of his fire. Alas, Clive's promising career is to end in tragedy at the hands of a mysterious dark Eikon, Ifrit, setting him on a dangerous road to revenge.

Clive Rosfield is the main protagonist of Final Fantasy XVI. He's the Archduke of Rosaria's elder son and Joshua's brother and he is also the Dominant of the dark Eikon, Ifrit.

Despite being the firstborn, Clive didn't inherit the power of the Fire Eikon, Phoenix, from his father; the role of its Dominant passed on to the younger Joshua instead. To find a purpose for himself, Clive became the First Shield of Rosaria, tasked with protecting Joshua and blessed by the Phoenix, allowing Clive to use part of its flames. Tragic events involving the dark Eikon, Ifrit, lead to Clive embarking on a quest for revenge. At the beginning of the story, Clive is 15 years old.
