Regula is known as a man of honor, and his loyalty to Varis zos Galvus is well documented. Though he openly shows disdain for those who oppose the will of the Empire, he is not above making alliances with former enemies if it is for the common good.

Final Fantasy XIV: HeavenswardEdit

FFXIV Regula

Regula in the Sea of Clouds.

Regula is first encountered when the adventurer and Alphinaud Leveilleur arrive in the Sea of Clouds in pursuit of Archbishop Thordan VII. Seeking the key to Azys Lla in the possession of the primal Bismarck, he confronts the pair alongside Emperor Varis Zos Galvus. They are forced to withdraw when Lucia comes to their aid in a suit of Magitek Armor.

When the adventurer's party breaks the barrier to Azys Lla, Regula ambushes them aboard a massive Garlean airship, the Gration. Though Ysayle, in her primal form of Shiva, saves them and damages Regula's dreadnaught, she is slain by an onslaught of fire power. The Gration is forced to remain moored at Azys Lla due to the engines being frozen.

The adventurer encounters Regula on the surface of Azys Lla, near the Garlean outpost at the Gamma Quadrant, and engages him in battle alongside Alphinaud, Y'shtola, and Estinien. Following this battle, Regula orders his troops to keep them engaged, while he goes on ahead to the Aetherochemical Research Facility where he engages the adventurer once more in battle, but flees upon defeat.

The Gears of ChangeEdit

FFXIV Regula Flagship

Regula appears after the Warrior of Light defeated Sephirot.

After the Adventurer, Krile , and Unukalhai successfully defeat the primal Sephirot, Regula briefly confronts Unukalhai. Although he rebuffs Unukalhai's condemnation of the Empire's attempt to control the Primals' power, he leaves without a fight.

Revenge of the HordeEdit

When the wards that Urianger Augurelt created in order to seal off the Aetherochemical Research Facility are removed, Regula enters the facility with a troop of Garlean soldiers, hoping to find the "Genesis Expression", one of the most powerful pieces of Allagan technology. Unbeknownst to him, the wards had been removed by Unukalhai, who had hoped to lure him into a trap during which he could be killed. The Adventurer, Krile, Y'shtola, Urianger, and Unukalhai follow him in. The Adventurer battles Regula, and once more defeats him. Cornered by the Scions, he again ridicules their arguments against the Empire's activities, but states that dying won't help his emperor's plans and escapes.

The Far Edge of FateEdit

When the Scions arrive on Azys Lla in order to defeat Zurvan, the final remaining member of the Warring Triad, Regula approaches them and offers to join them in an alliance. Having decided that the Allagan technology used to bind Primals is flawed, and thus unworthy to obtain for his emperor, he now seeks to destroy Zurvan. Together with the Scions, he ventures into Containment Bay Z1T9, where his troops are already battling Zurvan's awakened thralls. In the ensuing battle, Regula rushes to protect a vulnerable Unukalhai, but is mortally wounded by Zurvan in the process. With his dying words, he implores the Adventurer to continue to protect the world from the threat of the Primals, and encourages Unukalhai to use his powers to do the same.

After Zurvan's defeat, Regula's men prepare to bear his body back to Garlemald, while the Scions are left to acknowledge that courage and sacrifice exist even among their enemies in the Garlean Empire.

Spoilers end here.
