Clever men die just as quick as the rest.
—Ser Grinnaux

Ser Grinnaux de Dzemael is a member of House Dzemael and nephew of the count. Ser Grinnaux the Bull is a peerless warrior. Yet while his combat abilities were exceptional, his diagreeable personality led to more than a few altercations with others.

By his twenty-ninth nameday, Ser Grinnaux had earned a notorious reputation for his brawls at the local taverns and his willingness to strike knights who questioned this judgment on campaign. It was through a drunken quarrel that he became close friends with Ser Paulecrain. Unfortunately for some, Ser Grinnaux's peerless resulted in the occasional fatality, which the Count de Dzemael would be quick to conceal with coin.

He is also a recurring boss in Final Fantasy XIV: Heavensward. He is first encountered in a solo instance battle during the quest "Divine Intervention", wherein he restrains Alphinaud with Holmgang, and latter reprises as the second boss of The Vault. Finally, he appears as an enemy in The Singularity Reactor.
