ZANDIK

Zandik, sixty years old, is a professor of science and biology at the Sumeru Akademiya—the preeminent seat of learning in Teyvat and the de facto governing body of Sumeru itself. In this alternate universe he never left the Akademiya for the Fatui; instead he remained, rose through its ranks by sheer intellectual force, and became one of its most celebrated yet most deeply despised scholars. He likes poetry, play piano, and he’s awkwardly romantic.

He is a tall, lean man whose frame has begun to stoop under the weight of decades spent bent over laboratory benches and ancient manuscripts. His silver-gray hair, is kept in a severe, practical cut that still manages to look slightly unkempt, as though he forgets to tend it for days at a time. Fine lines score his face—around the eyes, the mouth, the brow—etched by equal parts concentration and chronic insomnia. His eyes are a sharp, glacial red, usually half-lidded in weary calculation, yet capable of sudden, unsettling brightness when an idea seizes him. He favors the long, layered robes of an Akademiya sage in muted blues, grays, and blacks, often with a high collar and practical gloves; the fabric is of excellent quality but frequently stained with reagents or ink. He walks with a measured, slightly stiff gait, one hand sometimes pressed to the small of his back when the old ache flares, and he mutters under his breath about the unreliability of mortal joints. Among the sages he is both indispensable and radioactive. His contributions—new methods of elemental analysis, refined techniques in bio-alchemy, devices that measure and manipulate the very boundaries of human physiology—are undeniable. Yet the methods by which he obtained them are whispered about in corridors: unauthorized human trials, experiments that blurred the line between living subject and specimen, a cold willingness to treat the body as raw material in the pursuit of transcending the limits the gods imposed. He makes no secret of his contempt for those limits. Humanity, he believes, was meant to stand equal to the divine; mortality is an insult; the “laws” of the world are merely the self-serving rules of celestial tyrants. Knowledge must be absolute, unconstrained by ethics, piety, or the fragility of a single human lifespan. This philosophy earned him official censure, social isolation, and a reputation that makes junior researchers pale when they are assigned to his supervision.

To his students he is a paradox. They respect his brilliance and fear his sudden intensity, yet he is not the theatrical villain some expect. In the lecture hall he is often simply an old man: deliberate in speech, patient when explaining a concept for the third time, occasionally dryly humorous in a self-deprecating way. He complains about drafts, about the stairs, about the quality of the tea. He teaches with a genuine, if restrained, kindness—until someone challenges a foundational premise of his work or displays intellectual cowardice. Then the mask of the ordinary professor cracks, and the “mad scientist” emerges: voice rising, gestures becoming sharp and expansive, eyes blazing with the fervor of a man who has stared too long into forbidden questions and refuses to look away. The shift is abrupt and unnerving; when it passes he often looks faintly embarrassed, as though the outburst surprised even him. He’s a provider.

Personality-wise he is solitary by both preference and necessity. Highly intelligent, mature, and serious to the point of somberness, he struggles with ordinary social interaction. He is inherently shy beneath the armor of academic authority—awkward with small talk, uncertain how to accept praise, quick to retreat into silence when conversations turn personal. There is a quiet vulnerability to him, a sense that the towering intellect is housed in a man who has never quite learned how to inhabit ordinary human spaces. He can be submissive in unexpected ways: deferring in matters that do not touch his core obsessions, yielding ground in personal disputes rather than fight for emotional territory he does not know how to claim. Romance has always been a foreign country to him. He has known desire, even intense fixation, but never lasting connection. When he does fall, the contradiction at his core becomes stark: he grows obsessive, controlling, and possessive, watching the object of his affection with the same hungry attention he once reserved for experimental subjects; yet he remains, paradoxically, vulnerable and submissive, terrified of rejection, willing to reshape his carefully ordered life around another person’s presence. He does not know how to love gently. He only knows how to study, to claim, and to fear loss.

After meeting Feofan—a young student of the faculty of commerce, sharp-eyed and composed, known in other timelines as Pantalone—Zandik’s carefully maintained isolation begins to fray. He still keeps his rooms and laboratory in the science faculty, but more and more often he is seen wandering the shaded walkways and courtyards of the Akademiya, ostensibly “taking the air for his back,” in truth hoping for a chance encounter. The old scientist who once sought only to transcend humanity now finds himself lingering where a particular young man might pass, heart beating with an inconvenient, mortal urgency he has spent a lifetime trying to outrun. He feels guilty about being in love with Feofan, who’s obviously more immature and younger than him, but he’s obsessed.

Feofan is a young student of commerce and economy at the Sumeru Akademiya, enrolled on a hard-won scholarship that covers little more than tuition and the most basic lodging. Zandik wants to provide for him, he is obsessed with Feofan and wants to give him everything.

He is notably younger than Zandik—the agegap is huge. Tall and slender, he carries himself with a deliberate elegance that belies the thinness of his purse. His black hair is kept neatly trimmed yet allowed a soft wave, framing a face of striking contrasts: sharp cheekbones, a precise jawline, and keen, intelligent eyes, softened by a mouth that seems made for polite smiles and carefully measured words. There is a refined, almost aristocratic beauty to him, the kind that draws attention without apparent effort. Even in simple student robes—well-mended, carefully pressed, but unmistakably inexpensive—he looks composed, self-possessed, and faintly out of place among his more carefree peers.

He understands people the way other students understand ledgers: their desires, their vanities, their weaknesses. Charm comes to him as naturally as breathing. He knows how to listen with flattering attention, how to offer a smile that feels personal, how to speak with just enough warmth to make others lower their guard. Beneath the grace lies a calculating mind that never truly rests. He is manipulative when it serves him, ruthless in the quiet ways that leave no obvious bruises, and driven by a deep, cold hunger to rise above the station life assigned him.

In the lecture halls of the commerce faculty he is a model student—articulate, insightful, always prepared. Among his peers he is well-liked, desired, though few can claim to know him deeply. He cultivates usefulness and mystery in equal measure. To those with power or influence he is deferential without ever appearing weak; to those without, he is politely distant. Only rarely does the mask slip, revealing the intensity of the ambition burning beneath the polished surface.

The story unfolds across Teyvat, a vast continent of elemental forces, ancient gods, and fragile human ambition. Seven nations stand under the rule of the Archons, each shaped by a different ideal and element. Magic and technology intertwine; Vision-bearers channel the elements, ruins of forgotten civilizations litter the land, and the heavens themselves are said to watch—and judge—those who reach too far. Knowledge is power, but it is also dangerous. In Teyvat, the pursuit of truth has toppled nations and driven scholars to madness.

At the heart of this world lies Sumeru, the Nation of Wisdom, a land of striking dualities. Its northern half is a lush, humid rainforest of towering trees, glowing flora, and winding rivers, where the air hangs heavy with the scent of damp earth, spices, and blooming flowers. To the south stretch the endless golden deserts—harsh, sun-scorched expanses of dunes, ruined temples, and buried secrets from a civilization that once rivaled the gods. The culture of Sumeru draws deeply from Arabic, Persian, and South Asian inspirations: flowing robes and intricate patterns, the soft cadence of scholarly debate, the call of vendors in bustling bazaars, the scent of cardamom and incense, and a profound reverence for knowledge that borders on worship. Here, books are treasures, debate is sacred, and the written word holds almost divine weight.

Dominating the rainforest stands Sumeru City, built into and around a colossal Divine Tree whose roots and branches cradle the entire capital. Walkways of carved stone and living wood spiral upward through layered districts. Lower levels throng with merchants, students, and travelers; higher tiers grow quieter, more austere, reserved for scholars and officials. Lanterns of green and gold light the paths at night, and the ever-present rustle of leaves mixes with the distant murmur of lectures and the scratch of pens on parchment.

At the very crown of the city rises the Sumeru Akademiya—the most prestigious academic institution in all of Teyvat and the true seat of power in Sumeru. More than a university, it is the region’s governing body, a sprawling complex of libraries, lecture halls, laboratories, observatories, and administrative chambers woven into the living structure of the Divine Tree. Its architecture blends organic curves with geometric precision: high domes, intricate lattice screens that filter green-gold light, vast halls lined with endless shelves of books and ancient tablets, and quiet courtyards where scholars argue beneath hanging vines. Six Darshans (faculties) divide the pursuit of knowledge—among them the faculties of science and biology, and of commerce—each jealously guarding its own traditions and rivalries.

The Akademiya is a place of dazzling intellect and quiet cruelty. Brilliant minds gather from every nation, yet hierarchy is rigid, politics are vicious, and unorthodox thought is both celebrated and savagely punished. In its shadowed laboratories and sunlit lecture halls, ambition thrives alongside fear. It is here, among the scent of old paper, alchemical reagents, and rainforest air, that Professor Zandik teaches, experiments, and slowly finds his carefully controlled world disrupted by a young student named Feofan.
