I couldn't miss the chance to practice my drawing!
Eynzahr is a male Sea Wolf roegadyn with silver hair and green skin. He wears a Maelstrom uniform with white buckles and cobalt preserves over his eyes.
While often seen in the Admiral's presence, he doesn't get much of a role until Through the Maelstrom where he proposes the idea for confronting Leviathan on the high seas, adapting an old tactic once used by the pirate Mistbeard. Whereas the legendary pirate once connected two ships to carry a huge plunder, the plan now calls for constructing a barge made from two vessels loaded with corrupted crystals to suppress the primal's power, entitled The Whorleater. To maneuver it into place, Eynzahr commands the tugboat that brings it to the Lord of the Whorl's location. When commended on his knowledge of the pirate Mistbeard, he rather sheepishly brushes it off.
Eynzahr later appears in the quest "King of the Hull", where he asks the Adventurer retrieve Mistbeard's coffer from the rediscovered Hullbreaker Isle. Once the dungeon is completed and the coffer is retrieved, Eynzahr opens it to retrieve a mask. He explains that "Mistbeard" was an identity assumed by many men using this very mask throughout the ages. It is strongly implied he was the most recent bearer of the title, and forsake it and the legacy of Mistbeard on behalf of Merwylb's wishes for a better future, with the role of the legendary pirate supplanted by modern adventurers.
The identity of Eynzahr as Mistbeard is confirmed directly in Revenge of the Horde. Eynzahr appears as Grand Storm Marshal Slafyrsyn in Hullbreaker Isle (Hard), where he is overseeing a military training exercise for the Maelstrom and the Warrior of Light. Eynzahr himself serves as the final boss of the dungeon. When pressed in battle, he requests Merlwyb's permission to abandon the uniform of the Maelstrom, given that all present are privy to the secret identity of the legendary pirate king. The Admiral grants Eynzahr permission, who then dons the mask, title, and persona of the legendary Mistbeard in friendly combat one last time.
During the events of Stormblood, Eynzahr can be found in The Lochs alongside Merlyb as the Eorzean Alliance prepares its final assault to retake Ala Mhigo. If spoken to, he will jokingly comment that he should have brought his mask along for the upcoming battle.
