## Profile

### Identity

Saber's true identity is **Byleth Eisner**, The daughter of Fodlan's legendary mercenary Jeralt the Blade Breaker, Byleth accompanied her father in his work and became feared and revered in their profession as the Ashen Demon for her reputation of destroying enemies without a hint of emotion on her face. An unexpected encounter resulted in her and Jeralt protecting the future leaders of the Adestrian Empire, the Holy Kingdom of Faerghus, and the Leicester Alliance from a bandit raid, and she was granted a position as one of their professors at Garreg Mach Monastery out of gratitude and in recognition of her skills. Unknown to her at the time, however, an epochal war was silently brewing, and her decisions would go on to shape the future of the Fodlan continent.

### Personality

Byleth has a very subdued personality and has difficulty expressing emotion. As a newborn, she neither laughed nor cried. People she is especially close to, such as Jeralt, are able to tell how she is feeling despite her limited emotional visualizations. A handful of her students note that her outward expressions hardly vary. Some express surprise whenever they simply smile. According to Alois, this trait of hers may in part come from her father, as Jeralt does not show his emotions easily either and can also be difficult to read. This should not be taken as them not having emotions at all however. Due to Jeralt concealing a lot of information about the world, she is showing curiosity about the influence of the Church of Seiros, the mystery of the Crests, and the dynamic of the three nations once she were immersed into the Officers Academy.

Her stoic demeanor slowly changes over the course of the Academy phase. Jeralt notices that she has become more expressive over the first few months, likely a result of the bonds she had formed with their students. Despite appearing indifferent, Byleth can be perceptive of their students and fellow faculty's problems and serve as a great source of emotional support for their issues. As the story unfolds, their emotions become more dynamic including feeling true sorrow, vengeance, and happiness.

Byleth has somewhat of a reputation from her earlier years in her father's mercenary corps for being a fearless and skilled warrior, gaining the moniker of 'Ashen Demon', due to the way she seemingly emotionlessly cut down her enemies in combat. This seems to be somewhat of a sensitive subject for her, as she seem uncomfortable when Hanneman mentions her moniker in her C support. It is notable that in the beginning of the game, Sothis refuses to let the player progress if they do not acknowledge their humanity to her, refuting the "Ghost" and "Demon" options, so it can be inferred that Byleth is uncomfortable with the Ashen Demon moniker because it dehumanizes her.

The three house leaders of the Officer's Academy attest to her martial prowess and have deep, profound respect for her abilities and guidance in battle and in the classroom. She alongside the other students continue to refer to her as teacher or professor even after the time-skip. The three house leaders also deeply regret that Byleth had not chosen their house if she is not teaching theirs, seeing the value in their strengths.

According to both genders of Byleth in Heroes, they do not actually know the distinction between a friend and an ally due to their unusual childhood. Nevertheless, they are well liked by the student body, even those not in in their initial house. Their wisdom ultimately shapes the outcome of the events of Three Houses providing council and guidance to the house leader they chose to teach, helping to shape them into better warriors and leaders.

Several students can develop an interest in them and eventually switch over to their house if not already in them. This results in them also joining her faction during the War, even those from enemy nations defecting to their cause, thus changing their fate. Those who do not join will often express regret facing her in battle. However, some students and faculty members, especially in the Crimson Flower route, will instead express outrage at her, vowing to kill her by their own hands.

According to her profile in Cindered Shadows, Byleth has interests in helping and listening to people, likes swords, reliable allies, smiles, and being trusted, and has no apparent dislikes.

## Abilities

Gifted (A skilled combatant that bested countless opponents during their career as a mercenary and is depicted as a gifted teacher, capable of bringing out the potential within their students and help them excel, even in topics they are not good at. Played an instrumental role in the war, leading their chosen house and army to victory, despite the numerous odds and setbacks that plagued them since Byleth’s abrupt disappearance, ending the war that lasted for five years in a matter of months under their leadership. As a professor, Byleth has profound knowledge in combat instruction, being personally proficient in Sword, Brawling (Martial Arts), and Authority (Commanding a Battalion), with hidden talents in White Magic, though they can also instruct in topics outside of those to almost the same degree. Can potentially become the first leader of the United Kingdom of Fódlan or Archbishop of the reform Church of Seiros).

Their magic have limited uses per battle. Divine Pulse has a limit to how far back it can rewind time, and has a finite amount of uses. Using a Hero’s Relic can be taxing on the wielder, wearing away at their soul, and a result of over-usage, can risk the chance in the user transforming into a Demonic Beast. Using the Combat Arts of the other Heroes’ Relics will cost more durability on the weapon than normal due to using Dragon Signs to draw out their full power.

### Parameters

* Strength (B+ Rank): Byleth is an expert at hand-to-hand combat and has an innate talent for brawling. She packs a punch and is much stronger than she looks.

* Endurance (B Rank): Byleth is a trained mercenary who is used to the hardships of life on the road and on the battlefield. She can take several hits and retaliate in kind.

* Agility (C Rank):Although Byleth is an incredibly strong and powerful fighter, she is a bit on the slow side and relies more on tactics than speed to outmaneuver enemies in combat.

* Mana (A Rank): Byleth is sustained by the Crest of Flames and sees battles through from beginning to end.

* Luck (C++ Rank): Byleth is an expert at winning battles and overcoming the odds to achieve victory, but she is less successful at challenging fate and was unable to save her father's life despite her Divine Pulse noble phantasm. Her luck increases with military affairs and in active combat, and it can increase further when the one who watches over her through the Crest of Flames intervenes.

### Class Skills

* Magic Resistance (B+ Rank): Magic users are plentiful in Byleth's era, and she has faced many enemy magi and fought multitudes of demonic beasts. Spells with three verses or less are ineffective against her, and even High-Thaumaturgy and Greater Rituals have difficulty affecting her. Because of her Crest of Flames, it is possible for her to display even greater resistance.

* Riding (D Rank): Byleth can handle most vehicles and animals with above average skill, but she has no special talent for riding and will have difficulty controlling untrained beasts.

### Personal Skills

* Professor's Guidance (B+ Rank): Unlike Discerning Eye, which reveals how a person's abilities can be used to their maximum effectiveness, this personal skill maximizes the effectiveness of the user's teaching. Byleth's Professor's Guidance improves performance and mastery for her pupils in the fields she has them focus on, and with the plus modifier she can also manifest low levels of Charisma towards those she mentors.

* Mercenary Tactics (B Rank): Before becoming a professor at Garreg Mach Monastery, Byleth fought as the Ashen Demon alongside her father, Jeralt Eisner the Blade Breaker of Fodlan, in his band of mercenaries. She is a highly skilled commander of battalions, companies, and strike forces, and this skill allows her to acquire tactical bonuses on the battlefield for herself and those under her command. However, because Mercenary Tactics is a skill specialized on winning battles instead of wars and utilizing small numbers of soldiers to maximum effect, it is unsuitable for leading whole armies and devising grand campaign strategies.

* Magecraft (C+ Rank): Byleth can cast simple spells in combat and understands the principles and theories of magecraft well enough to teach the basics. She also possesses a natural talent for divine magic, and her Crest of Flames allows her to occasionally perform feats of magecraft higher than her rank in this skill warrants.

* Crest of Flames (EX Rank): Also known as the Crest of the Goddess, this fire emblem is actually the heart of the Progenitor God Sothis. Implanted into a stillborn Byleth to save her life, this crest occasionally boosts her physical and magical might and converts the damage from these augmented strikes into extra vitality, in addition to a host of other incidental effects. At EX rank, the goddess herself awakens and accompanies the one who bears her heart, enabling possible divine intervention.

### Noble Phantasm

#### **Divine Pulse; "Both Sides of Time are Revealed"**

"*I shall permit you to turn back the hands of time, but know this power is not infinite!*" ~ Sothis, Girl on the Throne.

Through the blessing of the Progenitor God Sothis, Byleth can temporarily reverse the flow of time and rewind to the very recent past, completely negating causal effects and damage. Only persons and creatures with clairvoyance-like abilities to see through time or who exist outside the domain of time will not have their consciousness affected by this high-level reversion. Byleth can use Divine Pulse a maximum of thirteen times, and it activates automatically if Byleth suffers a lethal blow and perishes. Turning back the hands of time by more than fifteen seconds is extremely difficult, and going back a full minute or further will generate resistance from the world. Uses of Divine Pulse can be recovered by resting.

#### **Sword of the Creator; "Ruptured Heaven"**

The Sword of the Creator, famously wielded by Fodlan's legendary King of Liberation, Nemesis. Said to have been gifted to Nemesis by the Goddess, this weapon was actually crafted from Sothis's corpse after Nemesis slew the goddess's incarnation while she slept. The sword is a divine weapon with anti-dragon properties and can extend like a whip, but its true power only manifests when used by a wielder bearing the Crest of Flames. The sword is then able to channel the overwhelming divine power of the goddess and can consume even the darkness itself and slash through the boundaries between dimensions.
