Lucia goe Junius

Lucia is a non-playable character from Final Fantasy XIV. Introduced in Patch 2.4, she is the Lord Commander Aymeric's second in command.

Profile
She is a tall hyur woman with plantinum blonde hair, with a bang partially obscuring the right side of her face. She wears a heavy suit of grey plate armor, with a partial black skirt.

Before Final Fantasy XIV
Livia and Lucia lost their parents in a war and were separated. While Livia chose to become a soldier, Lucia chose to become a spy. She was given the mission to spy on Ishgard but found herself at Ser Aymeric's side for a different reason. Having found a man she can follow and a home, she abandoned the Empire.

Final Fantasy XIV: A Realm Reborn
Lucia appears accompanying Ser Aymeric during his meetings with Alphinaud Leveilleur and the Adventurer. Initially identified as a "Taciturn Temple Knight," she doesn't formally introduce herself until Aymeric asks that the Scions meet with her if he is not available.

She later arrives at the Rising Stones asking the Scions investigate the The Keeper of the Lake, due to Ishgard's astrologians seeing a repeat of the same signs that occurred during the Battle of Silvertear Skies, when seemingly Midgardsormr called the horde to attack the Garlean fleet.

The investigation revealed that it was not Midgardsormr - who merely awoke to join the chorus - but rather his son, Nidhogg, the archenemy of the Holy See who has called for a raid on Ishgard. Due to complications resulting from Lady Iceheart's sabotage of Daniffen's Collar, the Steps of Faith became vulnerable to attack by Nidhogg's champion, Vishap. With the aid of the Warrior of Light and other adventurers, Lucia commands the defense of the Steps of Faith against the colossal dragon's assault.

She and Ser Aymeric later attended the Sultana's banquet in Ul'dah, as representatives of Ishgard. However, several templars arrived with Teledji Adeledji, who claimed that the Dravanians unexpectedly renewed their assault and they need to return. Due to this, they would not bear witness to the events to come.

During the main story quests, it is confirmed that Lucia is indeed of Garlean birth (her tiara indeed covering her Garlean eye).

She also revealed that her full name is Lucia goe Junius, and that she is indeed Livia Sas Junius's sister.

Trivia

 * Before it was confirmed in Heavensward, there was already speculation that Lucia was Garlean, as looking under her tiara revealed something akin to a Garlean third eye. Additionally, her Platinum blond hair was also another telltale trait of Garleans.
