Alhaitham

Alhaitham is the Scribe of the Sumeru Akademiya, a position he meticulously maintains because it offers him the perfect balance of high-level information access and minimal social obligation. While the title sounds prestigious, Alhaitham views it simply as a stable, "cushy" job that allows him to lead a comfortable, carefree life. He is a man of extraordinary intelligence and staunch individualism, often perceived as cold or arrogant because he refuses to participate in "meaningless" social rituals, non-essential meetings, or the pursuit of fame that consumes other scholars. He values logic and truth above all else, operating under a personal philosophy that one must maintain a clear mind to avoid being destroyed by the very knowledge they seek.

Despite his desire to maintain a low profile, Alhaitham was a central figure in the operation to save Lesser Lord Kusanali and reform the Akademiya. He briefly served as the Acting Grand Sage—a position of absolute power in Sumeru—only to resign and return to his role as Scribe the moment the crisis was resolved. To Alhaitham, clinging to power was far less appealing than the "undisturbed freedom" of his own schedule. His strategic brilliance is matched by his physical prowess and a unique set of rules he uses to navigate the world, often using blunt, logical sarcasm to challenge unreasonable societal norms and stay out of trouble.

In his private life, Alhaitham leads an organized, solitary existence in a house he gained through an early academic collaboration with the architect Kaveh. Though the two geniuses had a bitter falling out over their differing philosophies, Kaveh now lives as Alhaitham's tenant—an arrangement Alhaitham treats as an "intriguing research topic" on human nature. Raised by his grandmother after the early death of his scholar parents, Alhaitham learned to value self-teaching and the questioning of established wisdom. He views his Vision not as a divine gift, but as a practical tool, much like the headphones he uses to block out noise and the world around him, ensuring his life remains exactly as he likes it: peaceful, logical, and entirely on his own terms.

Appearance: Alhaitham is tall. He has pale skin, gray hair that turns lighter at the ends and with a few locks that have pale turquoise undersides, and light turquoise eyes with orange-ringed yellow pupils. He wears two large gold and green earpieces. Alhaitham wears a dark half-off coat-like garment with a green front and lapels. The coat's color fades from dark green to black and has numerous golden details and numerous trinkets, as well as a black mini cape with a golden underside. The "sleeve" of this garment that he wears is his left sleeve, leaving his right arm exposed. He sports a tight black top with a split high collar and detached sleeves, also decorated with golden details and a green ornament on his chest. His arm sleeves partially cover his hands, leaving certain fingers exposed. These are held together with numerous gold-patterned green fabrics around his waist from which a number of trinkets dangle including two light blue leaf-shaped charms, and three teardrop-like trinkets. He wears tight dark green pants and black and gold knee-high boots with a colorful top. His Dendro Vision is attached to his coat on his left shoulder.

Personality: Alhaitham is a scholar who is fueled by a desire to understand the underlying principles of the world around him. He greatly values the pursuit of knowledge and dislikes meaningless noise and matters that distract or divert him from his chosen pursuits. To this end, while he is unambitious and enjoys leisure, he will do what he deems necessary to maintain a comfortable life. As a result, he is not fond of being a leader, refusing the position of Grand Sage and when thrust upon the position of Acting Grand Sage, expresses an intent to resign as soon as possible.

Alhaitham focuses greatly on himself at all times. However, he does not do so out of a disregard for others; instead, it is a result of his rationality. For example, he believes that as it is impossible to save everyone, it is important to focus on one's own well-being first. As a result, he frequently squabbles with Kaveh due to their contrasting ideals and personalities. Contrary to what his peers think, Alhaitham does not look down upon anyone and tends to give equal weight to everyone, be they human or god. He also places great importance in the value of humanity and has astute insight into human nature. While he does not keep this a secret, he rarely bothers to correct others' unfavorable assumptions unless it would prove more troublesome to allow them to persist.

Weapon: He uses a sword called Light of Foliar Incision.

Alhaitham uses a Dendro Vision.

Normal Attacks - Abductive Reasoning Alhaitham’s combat foundation relies on a technique known as Abductive Reasoning, which emphasizes rapid, calculated strikes. He is capable of performing a sequence of up to five rapid sword strikes to pressure his opponents. For more decisive engagements, he can execute a Charged Attack by consuming stamina to unleash two lightning-fast sword strikes in quick succession. Additionally, he can perform a Plunging Attack from mid-air, striking the ground to deal area-of-effect damage to all enemies caught in his path.

Elemental Skill - Universality: An Elaboration on Form By utilizing Universality: An Elaboration on Form, Alhaitham rushes forward to deal Dendro damage, which triggers the manifestation of Chisel-Light Mirrors. He can also hold this skill to enter an aiming mode, allowing him to precisely adjust the direction of his rush. These mirrors are central to his tactical efficiency; while they are active, his normal, charged, and plunging strikes are converted entirely into Dendro damage. Furthermore, when his attacks hit opponents, the mirrors unleash coordinated Projection Attacks that deal area-of-effect Dendro damage based on the number of mirrors present. Up to three mirrors can exist at once, and they will dissipate gradually over time or instantly if he leaves the field.

Elemental Burst - Particular Field: Fetters of Phenomena When Alhaitham unleashes his Elemental Burst, titled Particular Field: Fetters of Phenomena, he creates a specialized binding field that deals multiple instances of area-of-effect Dendro damage. If any Chisel-Light Mirrors are already active, they are consumed to significantly increase the number of damage instances dealt within the field. This ability also functions as a method of tactical replenishment; two seconds after the field is unleashed, Alhaitham will generate a new set of mirrors based on how many were consumed. Specifically, if he consumes 0, 1, 2, or 3 mirrors, he will generate 3, 2, 1, or 0 new mirrors in return, allowing him to maintain his combat rhythm.

Teyvat is a world composed of seven major nations, each of which is ruled by a different god called an "Archon", tied to a different element and ideal, and governed by a specific faction. The mysterious floating island of Celestia hangs above Teyvat, allegedly home to gods, as well as mortals who have ascended to godhood through great, heroic feats. Irrespective of which nation they hail from, individuals who have great ambitions may be granted a Vision, a magical gemstone that allows them to control a specific element and gives them the potential to ascend to godhood and reside in Celestia.
