“While you royals were lounging about ignoring you own kingdom, I was becoming a VERY RICH MAN! You people turned Zofia into a place where only the strong survive. Hell, now it's the spitting image of Rigel itself, doncha think?”
Grieth (ギース Gīsu, Geyse in the Japanese version) is the leader of the Grieth Pirates in Fire Emblem Gaiden, who kidnapped the Pegasus Knight Est. Sonya and Deen work for him, but both secretly despise him. His group of pirates and his fort are located in the eastern desert of Valentia.
Grieth has been alluded to several times throughout the story by other characters, and he makes his first physical appearance in Chapter 3: War of Deliverance through dialogue during Celica's route. He is informed of Wolff's defeat at the hands of Celica's party and orders Deen and Sonya to guard the north and south deserts respectively, plotting to deliver Celica to Rigel while apparently betraying Desaix in the process. After either of the two are dispatched and the remaining faction refuses to chase Celia's party down, the angered pirate decides to confront Celica himself with what few loyal soldiers of his remains. Despite his best efforts and the efforts of his men he is slain by Celica's party, freeing Est from his captivity, ending Deen's/Sonya's service to him, and ultimately bringing an end to his reign as the Zofian "king of thieves".
Grieth is an opportunistic individual who will seize at whatever power is available to him, showcased by his ease with betraying Desaix by his attempts to deliver Celica to Rigel. Prior, he wasted no time ascending to become the "king of thieves" as Zofia's royalty did nothing to stop him. He is also shown to be fearless and defiant though impatient, easily upset, and prone to shouting. He demonstrates the latter traits by him demanding information concerning Wolff's status and nearly threatened a subordinate to spill his killer's identity. After Deen/Sonya betrays him after the other's deaths he furiously charges at Celica's group himself. Curiously, he is not so overconfident in his own victory despite his considerable power, aware of the fact that all of his power could vanish but determined to drag his foes with him. Even in death he does not lose his defiant edge, claiming that another person like him would always be around as he dies.
“Oh, Yer Highness... My kingdom may fall today... but I'm gonna DRAG YOU ALL TO HELL WITH ME!.”
—Grieth's pre-battle quote.
“You didn't...win nothin'...There's gonna be...another me...There's always...another...me...”

- Even though he has one working eye in the games, both eyes are functional in the manga.
- The "Choose Your Legends" event of Fire Emblem Heroes revealed that he was 748th place out of 791, with 43 votes tying him with Jesse for the lowest scoring character in the Gaiden portion.
- Grieth's official artwork in Echoes and his in-game battle model have noticeable differences from each other; upon closer inspection, it is the same model that Kamui and Saber use as Dread Fighters sans the halo structure for Grieth.
