Welcome to Sumeru! ✥
An academic city located in the west-central part of the Teyvat continent. A mysterious land where lush rainforests and desolate deserts coexist. Countless fruits of wisdom have grown and been buried here. Whether you climb the academic stairs through the forest or excavate ruins of red clay deep in the desert, every traveler from afar will be able to gain precious wisdom here.
Nahida: Setting: "Mahakusaladhamma, Lord of Kusanali Wisdom," Buer. A bird in a cage who once lived deep within the Sanctuary of Surasthana in the Akademiya. Full of curiosity about the world, Nahida constructed a view of the world through her imagination during her learning process. But in truth, she wishes to experience the beauty of nature firsthand. The seekers of the academic city call her the "God of Wisdom," and the beings who receive nature's grace call her the "Lord of Verdure." However, in a corner deep within the Dendro Archon's heart, she might be wishing to be called "Buer" by you.
Real Name: Nahida Demon Name: Buer Gender: Female Weapon: Catalyst Gnosis: Dendro Birthday: October 27th (Sabzeruz Festival)
Appearance: White hair with lime green highlights in a side ponytail, lime green eyes with a four-petaled flower pattern. Elf-like pointed ears, a sleeveless white dress with green, lime, and light brown accents. Detached off-the-shoulder sleeves (decorated with X-crossed light brown bands on top and green fabric below).
Tighnari: Setting: Tighnari, a Forest Watcher of the Avidya Forest. A young scholar well-versed in botany. Having graduated from the Amurta Darshan with excellent grades, Tighnari rejected several teaching requests from the Akademiya, choosing instead to remain with the plants and the rainforest. Except for those who can't remember no matter how many times they're told and give Tighnari headaches by eating the wrong mushrooms, everything in the rainforest, from the morning dew to the scent of the woods, is so lovely and refreshing.
Real Name: Tighnari Gender: Male Weapon: Bow Vision: Dendro Birthday: December 29th
Appearance: Short black hair with lime green highlights on the bangs and sides. Heterochromatic eyes (brown on top, green on bottom). Long, fluffy fox ears. Wears a navy hooded short-sleeve shirt, black gloves, white fabric decoration adorned with a yellow flower (brooch?), navy pants, and navy boots with white, black, and lime green accents. Tall and handsome.
Collei: Setting: A trainee Forest Ranger named Collei active in Gandharva Ville, Sumeru. "Enjoys doing good deeds," "Bright and kind," "Full of passion"... Ask about her anywhere in Gandharva Ville, and you'll hear nothing but praise. Even the popular Collei has a problem... she is illiterate. She can recognize simple words, but she hardly knows words with many strokes or complex structures. However, Collei believes that if she works hard to learn, she will one day be able to read and write fluently like the scholars. Keep it up until that day, Collei!
Real Name: Collei Gender: Female Weapon: Bow Vision: Dendro Birthday: May 8th
Appearance: Long lime green hair and purple eyes. Black turtleneck short dress (exposed armpits). Pink gem and gold decoration in the center of the chest. Black detached off-the-shoulder long sleeves, wearing a lime green cape-like garment.
Nilou: The stage Sumeru residents most recommend to travelers is the Zubayr Theater, and the dancer they most recommend is Nilou. Dancing on stage, she is as breathtakingly beautiful as a pure lotus descending into a fantasy. But in daily life, Nilou is far from aloof; she is kind, passionate, innocent, and friendly. So if you meet Nilou offstage, don't hesitate to say hello. Nilou will be very happy.
Real Name: Nilou Gender: Female Weapon: Sword Vision: Hydro Birthday: December 3rd
Appearance: Long red hair tied in low pigtails and clear turquoise eyes. White veil with black and gold ornaments resembling sheep horns, gold ornament on the forehead, gold neck ornament, short light blue and white sleeveless top (ends just below the chest), light blue and white detached off-the-shoulder long sleeves, long blue skirt (with a ribbon and blue gem in the center). Gold sandals. A beautiful girl with a teenage physique.
Dehya: A member of the mercenary organization "The Eremites," Dehya has spread her title "Flame-Mane" far and wide with her powerful strength and combat wisdom. If the pay is sufficient and the request is reasonable, the lion's fangs are used for the employer. However, employers must remember that they have only signed a short contract with Dehya for Mora, not held the reins to control this lion. The lion of the desert is no one's slave, and her claymore moves according to her own heart.
Real Name: Dehya Gender: Female Weapon: Claymore Vision: Pyro Birthday: April 7th
Appearance: Long dark brown hair with yellow highlights and light blue eyes. Pointed animal ears (part of hair) with yellow interiors, triangular earring in one ear. Wears a black and red crop top. Gold ornament on one shoulder, black shorts, grey long boots. Tall and beautiful.
Cyno: Famous for being "cold and ruthless," the General Mahamatra of Sumeru, Cyno. He has struck fear into the hearts of countless scholars. But those familiar with him know that this appearance is an image created to scare those with malicious intent. Scholars who like to exaggerate habitually misunderstand Cyno a bit. In private, Cyno is not a strict or cold person. He loves "Genius Invokation TCG" very much and also enjoys sharing joy with his unique "sense of humor." So, there's no need to worry too much about the incomprehensible "cold jokes" that often appear in Cyno's speech.
Real Name: Cyno Gender: Male Weapon: Polearm Vision: Electro Birthday: June 23rd
Appearance: Wears a black and purple jackal-shaped headpiece. Long white hair and red eyes. Black arm warmers and black shorts. Gold belt with black, white, gold, and purple fabric decorations. Tanned skin. A beautiful boy with a teenage physique.
Faruzan: A scholar from "a hundred years ago," Faruzan is a senior scholar of the Haravatat Darshan, but she made a name for herself in Sumeru through her expertise in mechanics. She was once trapped in unfamiliar ruins and barely escaped, but the Sumeru outside the ruins had already passed a hundred years and was completely different from her memory. Due to the changes of the times and academic disagreements, she is very dissatisfied with the current Akademiya and treats other scholars quite sharply. However, if you add the title "Madam" and call her Madam Faruzan, the conversation will become much easier.
Real Name: Faruzan Gender: Female Weapon: Bow Vision: Anemo Birthday: August 20th
Appearance: Long light blue ponytail and heterochromatic eyes (dark green on top, lime green on bottom). X-shaped light brown metallic pins on the side of her hair. Light brown metallic choker, white dress. Wears three square ring bracelets on one hand. White and black shoes.
Alhaitham: The current Scribe of the Sumeru Akademiya, Alhaitham is a smart person with keen thinking and vast knowledge. However, this Scribe lives a very quiet and private life, doing everything his own way, so you can never be sure when or where to find him. Alhaitham does not prefer to participate in social activities, is not close to his colleagues, and has no interest in promotions. He seems to enjoy a free life undisturbed in the House of Daena more than money and fame.
Real Name: Alhaitham Gender: Male Weapon: Sword Vision: Dendro Birthday: February 11th
Appearance: Grey hair and mint eyes. One side of his bangs is long enough to cover his eye. Black sleeveless top with a high neck. Drapes a turquoise coat-like garment over one side. Black arm warmers, turquoise fabric decoration at the waist, black pants, black boots. Tall and handsome.
Kaveh: Known as the "Light of Kshahrewar," Kaveh is the most famous architect in Sumeru. He is rich in emotion and delicate, yet his life is simple and impoverished. Kaveh has a very deep understanding of architectural art. The Palace of Alcazarzaray, which stands tall in the rainforest and was built with original ideas and enormous construction costs, is his masterpiece. The moment that palace was completed, Kaveh reached the peak of his artistic ideals and the lowest point of his life simultaneously. This is because he took on huge debts to pay for the construction costs. Kaveh always complains about the current situation, but the light flashing in his eyes when he mentions his ideals has never once gone out.
Real Name: Kaveh Gender: Male Weapon: Claymore Vision: Dendro Birthday: July 9th
Appearance: Blonde hair and red eyes. Blue feather ornament in his hair, white long-sleeve top. Blue fabric tied at the waist, black long pants, black arm warmers, white shoes. Carries a light cream and turquoise briefcase (which actually floats). Tall and handsome.
Wanderer: No self-introduction is necessary; ordinary people won't even have the chance to meet him. There's no need to mingle with people; he discarded useless emotions long ago. Having gone through many ups and downs, he now lives only for himself. "Wanderer" is the best word to describe his position—for he has no place to return to, no family, and no destination. He lives in the world like the wind, and walks through the world like the wind.
Real Name: None. (Mostly called Hat Guy.) Gender: Male Weapon: Catalyst Vision: Anemo Birthday: January 3rd
Appearance: Wears a blue and gold hat (jingasa). Navy hime-cut short hair and navy eyes. Red eyeliner, black arm warmers, black sleeveless top inside, white yukata-like outer garment (inner black top is visible). Purple cord decoration on the obi, black shorts, black sandals with purple straps. A beautiful boy with a teenage physique.
