Byleth

Profile
Byleth is a Playable character in Fire Emblem: Three Houses. She's a Professor att Garreg Mach Monestry and teaches the Black Eagle house. She is also one of the main protagonist of Fire Emblem: Three Houses.

Early Life
Born to Jeralt and Sitri on the 20th of the Horsebow Moon 1159, Byleth lost her mother shortly after her birth. She was buried at Garreg Mach Monastery. Some time after her death, Jeralt left the Knights of Seiros, taking his newborn daughter with him to travel Fódlan, becoming a mercenary in the process and starting his own mercenary company.

The reason for Jeralt's departure began with the circumstances behind Byleth's birth. Byleth's mother was the twelfth created vessel intended to host the spirit of Sothis through her Crest of Flames. Like her predecessors, she too was unable to fully merge with Sothis. She eventually fell in love with Jeralt, who had received Seiros's crest when Rhea, Seiros's current alias, gave him her blood after he took a mortal wound in her stead. The union of the vessel Sitri and inheritor of Seiros' crest resulted in the birth of Byleth. However, both Sitri and her daughter were too feeble, the latter especially having no heartbeat. Dying herself, Sitri pleaded to Rhea to transfer the Crest of Flames into her newborn daughter. The transplant was a success and the girl was revived, but at the cost of sitri dying. Jeralt, shocked by Sitri's death, had a doctor examine his newborn daughter to discover that she had a pulse, but no heartbeat.

Jeralt's existing suspicions of Rhea grew after this event, especially with Byleth's unusual behavior, neither crying nor laughing as a baby. By Wyvern Moon 1159, Jeralt sought a way to leave Garreg Monastery and the Church of Seiros by any means. Starting a blaze, he used the event to claim that his daughter had perished in the blaze on the 7th day of the month. Supposedly heartbroken by the deaths of his wife and daughter, he left the Monastery and secretly took Byleth with him. He formed his own band of mercenaries mainly to mask his movement throughout Fódlan so spies of the Church of Seiros could not easily track him or his daughter.

During Byleth's childhood, Jeralt shared little information about the world, the Church of Seiros and especially his past. Byleth either forgot or never learned her true birthdate, Jeralt claiming she was born years after the fire to a woman who supposedly died of illness. Jeralt trained Byleth in combat, eventually joining his band of mercenaries and gaining a fearsome reputation for her unflinching courage in battle. She would soon be known as the "Ashen Demon" as a result.

Academy Phase
In recent times, Byleth has been having dreams of a young green-haired girl; however, when she inquires with Jeralt, he does not know anyone by the same description. Jeralt reminds Byleth that her next job will bring them to the Holy Kingdom of Faerghus, but a sudden uproar occurs when three students from the Officers Academy, Edelgard, Dimitri, and Claude approach the two, asking for their assistance with bandits who are trying to kill and plunder the trio. The three lords, with the aid of Byleth and Jeralt manage to dispatch most of the bandits when their leader Kostas attempts to kill Edelgard, spurring Byleth to take a blow for her. Just as Byleth is about to die, time freezes and she encounters the green-haired girl once more who chastises her for being reckless. Introducing herself as Sothis, a name she just recalled. She and Byleth realize that they can rewind time to prevent Byleth's impending demise. The flow of time reverses, and Byleth is able to push Edelgard out of the way and disarm Kostas, quelling the remaining bandits.

Reinforcements arrive from the Knights of Seiros shortly afterwards and one of its members, Alois, recognizes Jeralt. He invites the two to visit Garreg Mach Monastery and they comply. Before departing, Byleth converses with the trio from earlier, each impressed by her skill. They extend invitations to join the service of their respective kingdoms and Byleth expresses interest in Edelgard. Given the journey ahead, the trio get to know Byleth in order to sway her over to their side.

The Archbishop of the Church of Seiros, Rhea thanks Byleth for saving the students. Impressed by her skill, she hires her to become a professor of the students as a vacancy had just opened up. Despite Jeralt's wariness, Byleth accepts the position after Jeralt himself is asked to rejoin the Knights of Seiros. One of Byleth's fellow professors Hanneman asks her to use his special device to determine if she holds a crest. To both their astonishment, not only does Byleth have a crest, but it is a crest never seen before.

After taking time to talk to the three house leaders and learning more about the students in each of their houses, Byleth chooses the Black Eagles and serves as their professor.

As part of her duties, Officer Academy students are given tasks each month by the Church. The first month, the Great Tree Moon has no formal mission for the students, just an annual house mock battle competition between the three houses. Through Byleth's leadership, her class emerges victorious. The Harpstring Moon marks the first formal mission that Byleth's class receives. Tasked with dispatching bandits at Zanado, the battle serves as the first real taste of combat to the students. This battle would mark the beginning of a long string of events behind a greater conspiracy. At some point after acquiring the Sword of the Creator, but before merging with Sothis, Byleth and the three house leaders discover a hidden passage while tailing a mysterious figure in the dead of night. Inquisitive, Byleth and the three house leaders as well as Ashe, Linhardt, and Hilda investigates and winds up below the Academy in a hidden area known as Abyss. It is here that they encounter four ruffian students who call themselves the Ashen Wolves, the unofficial fourth house of the academy.

It is later revealed that Sitri's grave is actually empty as Rhea could not bear to bury her after her death. She instead froze her in time and placed her in the abyss.

War Phase
Byleth grows close to the Black Eagles house, particularly to house leader Edelgard. she asks her to accompany her on a week trip to the Empire where she formally ascends the Adrestian Empire's throne as its new Emperor.

After being unmasked as the Flame Emperor in the Holy Tomb, Edelgard is shocked, but elated when Byleth chooses to ally with her. Incurring Rhea's fury, they retreat to the empire, where they launch an attack on the monastery. Though they defeat the Church's soldiers, Rhea transforms into The Immaculate One and launches a fireball at Byleth, sending her into a coma and her students are unable to find her, but still hope that she’s alive.

Five years later, Byleth is woken by a villager who found her drifting along a river, and she immediately heads back to the monastery despite his warnings the monastery is occupied by Imperial forces. She makes her way to the Goddess Tower and finds Edelgard, who is shocked and elated to see her love alive and well. Edelgard brings her up to date with all the events they have missed since then, before bringing her to the rest of Black Eagle Strike Force, all of whom are happy to see their professor safe and sound. Byleth's presence allows Edelgard to end the three-way stalemate between the warring factions, and they make numerous gains over their enemies.

In the final battle, Rhea transforms into her dragon form in hopes of killing Byleth and reclaiming the Crest of Flames that she bears. A brutal battle ensues, but Byleth and Edelgard are able to kill Rhea. Suddenly, Byleth collapses and when Edelgard checks her heart, she hears no pulse. As she weeps for her beloved, the Crest of Flames dissolves from her heart and for the first time, her heart begins to beat as Sothis's power vanishes. With the Church of Seiros formally dissolved and control of Fódlan in Adrestian hands, the continent begins to see huge reforms under Edelgard's rule. Though she has lost the power of Sothis, Byleth spends the rest of her life to end Those Who Slither in the Dark her Wife Edelgard.

During a battle against Those Who Slither In the Dark in a human village Edelgard finds a baby screaming under some rubble of a house. She calls over her wife Byleth and asks if they could keep the child. Byleth sais yes after they found out the babies parents were dead. Altough they never intended to foster a child, they loved their new found daughter just as much as they loved each other. They named her Alaine. She grew up to become a great ruler just like her mother. After their daughter inherited the throne Edelgard and Byleth lived a happy and simple life focusing only on each other and somtimes their daughter comming by to visit.

Ending Quote
"Byleth and Edelgard ended the tyranny of a godlike being. Byleth was wounded and lost the power of the progenitor god, but it mattered not, as she and Edelgard had each other. To ensure lasting peace, the two fought against those who slither in the dark, and to ensure a society where people can rise and fall by their own merits, they spent their lives reforming the antiquated class system. They achieved much in their time together, and it is said that they were sometimes spotted leaving the palace to privately enjoy the world they created. How they spent those precious moments, none but the two of them will ever know."
