Gaff Gafgarion

Gaff Gafgarion is a mercenary from Final Fantasy Tactics who is hired by Dycedarg Beoulve and Cardinal Draclau. He is a Dark Knight, possessing two powerful sword skills: Night Sword, which drains HP, and Dark Sword, which drains MP.

The Ovelia Mission
Gafgarion is hired by Dycedarg Beoulve to get rid of Princess Ovelia, who is in the way of Prince Larg's ascension to Regent of Ivalice in the name of Prince Orinas, who he plans to have coronated. Gafgarion accepts a mission from Agrias Oaks to protect Ovelia so that he can get close enough to do his job. He travels to Orbonne Monastery with his team, including Ramza Beoulve, Dycedarg's younger brother who knows nothing of the plot. The monastery is attacked by several Hokuten dressed as Nanten, and following the plan, Gafgarion stages a counter-attack on them. During the attack, Delita Hyral slips in a back door and kidnaps the princess.

Agrias is too slow to prevent Delita's escape, and Gafgarion and Agrias lead a pursuit team after him. They are attacked by a group of mercenaries hired by Vormav Tingel, but with the combined swordsmanship skills of Agrias and Gafgarion, the team easily wins and catches up to Delita at Zirekile Falls where he has encountered a group of Hokuten. Gafgarion reveals his true mission and attempts to kill Ovelia, but Delita is actually on the side of the Nanten, and therefore takes action to protect her. Ramza remains loyal to Ovelia and Agrias, and counterattacks Gafgarion, forcing him to retreat as Delita dispatches the Hokuten.

Between Dycedarg and Draclau
Dycedarg, however, is unwilling to give up. He has secretly entered into an agreement with Cardinal Draclau to get Ovelia, and sends Gafgarion to help Draclau. At Draclau's stronghold of Lionel Castle, Gafgarion finds that Ovelia has been captured, but that Draclau wants a Zodiac Stone that has fallen into Ramza's possession. After fellow mercenary Bart Rudvich fails to retrieve it, Draclau kills him and arranges for Gafgarion to create a trap: He will pretend to execute an Ovelia-decoy to lure Ramza to Golgorand Execution Site and several Lionel guards will then join him in an ambush.

Everything goes as planned until the trap is actually sprung. Despite being outnumbered, Ramza, Agrias, and Mustadio Bunanza, the original keeper of the Taurus Stone, fight back and defeat the Lionel guards. Gafgarion, growing weak, is forced to retreat back to Lionel, but readies a second ambush. As Ramza's forces arrive at Lionel, he attempts to scale the wall to open the gate for his men. Gafgarion appears and gives the signal: several Lionel guards including summoners emerge from hiding to attack Ramza's men, while Gafgarion challenges Ramza to a duel. Gafgarion keeps Ramza in a tight situation with his Night Sword, but Ramza ultimately prevails, killing Gafgarion.
