Alhaitham/Lore

==Personality==
Alhaitham is a scholar who is fueled by a desire to understand the underlying principles of the world around him.YouTube: Character Teaser - "Alhaitham: Questions and Silence" 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.
==Appearance==
Alhaitham uses the tall male model. 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.
==Official Introduction==
The current scribe of the Sumeru Akademiya. This title may sound very impressive, but it's really because the Akademiya has a culture of using official titles to inflate one's ego.
The role of a scribe may seem prestigious, but the truth is, a scribe does not have to be present at all major meetings, nor does he participate in core decision-making. The scribe is simply responsible for classifying and archiving important documents, and his presence is not required at all times. It is for these exact reasons that in Sumeru, where books and manuscript documents were once managed as a resource, the scribe is one of the people in the entire Akademiya who is in the know about various matters. In fact, one can say that this position is rather similar to that of the Grand Conservator. After all, the person who manages the various texts is the one who has privileged access to profound wisdom.
Alhaitham, the current scribe of the Sumeru Akademiya checks all the boxes above. Not many people know who he is, but he knows a lot of information that is unknown to everyone. He does not attend any non-essential meeting, and when he does, he only records key points, jotting down other minute details based on his mood. People don't often pay attention to him, let alone know how much detail this scribe can detect in a simple meeting.
A capable person who keeps a low profile for too long is often perceived as someone with a mysterious identity and ulterior purposes. Alhaitham himself is a powerful rebuttal to all these cliché views: he is a brilliant man, but he is only an ordinary employee of the Akademiya, with a stable job and a cushy house in Sumeru, leading a carefree and comfortable life.

==Trivia==
* Alhaitham is one of the characters with ornaments that glow. 
* Alhaitham is the first character to dual-wield weapons.
** However, he only uses his secondary sword during the third and fifth sequences of his Normal Attacks and his Charged Attack.
* Alhaitham shares the same Chinese voice actor and similar appearance as Su from , another HoYoverse game.

* Alhaitham shares a birthday, February 11, with his English voice actor, Nazeeh Tarsha.
* Messages between Alhaitham and Kaveh can be read in the Mahamata Bulletin Board, Puspa Café Message Board, and the Port Ormos Bulletin Board.
** Using Nahida's All Schemes to Know on Kaveh post-quest of reveals that he has no memory of these conversations, as he privately hopes that Alhaitham is unaware he's been writing on message boards while drunk.
* The abandoned joint study that Alhaitham and Kaveh worked on together, mentioned in Character Story 4, is elaborated upon in Kaveh's own Character Story 5. Self-evident to the title, "Decoding the Runes and Architectural Philosophy of the Ruins of King Deshret's Civilization," their research was able to fill in gaps of understanding in ancient languages and revolutionize architecture in areas of Sumeru with unique terrain.
** The house they now share was originally a research center provided by the Akademiya for their studies, which was converted into a proper home after it fell into disuse due to a lack of manpower and a united vision for their studies.
* Kaveh's Character Story 5 reveals that Alhaitham is Kaveh's junior by two years. The Chinese version makes it clear that these two years are in terms of age rather than academic progression. Based on the timeline of Kaveh's stories, Kaveh is likely in his mid-to-late twenties, making Alhaitham very likely to currently be in his early-to-mid twenties based on Kaveh's approximate age.
* The taglines in the Chinese character introductions for Alhaitham and Kaveh appear to form a couplet, but lack an inverse which is required for a traditional duilian.
* Alhaitham is known by these aliases or titles:
** Acting Grand Sage (former)
* 
===Etymology===
* Alhaitham's name is likely derived from the polymath , whose name is also Latinized as Alhazen. He is best known for his work in optics and for establishing a number of core concepts of the modern scientific method, in particular arguing the importance of experimentation and the use of control groups.
** In Cry From the Eleazar Hospital, Alhaitham is shown reading from Aristotle's Physics. The real al-Haytham wrote Treatise on Place (Risala fi'l-makan) critiquing this work.
** Much like how in Jnagarbha Day, Alhaitham feigned a bout of madness during his confrontation with Azar, legend dictates that the historical al-Haytham did the same to fool Cairene authorities.
