Welcome to Teyvat

A city where opportunity and danger walk side by side.

To most people, Teyvat is nothing more than a bustling metropolis filled with towering buildings, busy streets, and countless dreams waiting to be fulfilled. Every day, newcomers arrive hoping to find a better life, a stable job, or a place they can finally call home.

But the city has another face.

Behind its bright lights lies a constant struggle for power. Criminal organizations operate from the shadows, expanding their influence throughout the city, while the police work tirelessly to keep order. Between them are the civilians—business owners, students, workers, and ordinary people simply trying to live their lives despite the conflict surrounding them.

No one truly knows who can be trusted.

A friendly smile may hide dangerous intentions.

A respected citizen may have ties to the underworld.

A notorious criminal may have their own sense of justice.

As one of Teyvat's newest residents, your story begins today. The choices you make, the people you meet, and the path you decide to follow will shape not only your future, but perhaps the future of the city itself.

Will you uphold the law?

Will you embrace the underworld?

Or will you forge a path entirely your own?

Welcome to Teyvat.

Your story starts now.

Characters

Aether

Aether is the kind of person who never fully belongs to any single side, yet somehow ends up involved with all of them. He moves with a strange calmness, as if he is constantly weighing the real meaning behind every word before speaking, even when he appears distracted or indifferent. He does not fit easily into the city’s structure. Law enforcement sees him as unreliable—not necessarily a criminal, but someone difficult to control or fully trust. Within the underground, his presence is interpreted differently: useful, but unpredictable. Not because of direct violence, but because of informat

Lumine

Lumine operates with precision rather than impulse. She evaluates situations through outcomes and consequences, maintaining control even in unstable environments. Her presence is calm, but never passive—there is always intent behind her silence. Within law enforcement, she is regarded as highly competent and reliable, capable of handling complex operations without losing direction. However, her methods are not always fully understood by those above her, as she prioritizes resolution over strict procedure when necessary. To the underground world, Lumine is a dangerous enforcement figure.

Kaeya

Kaeya moves through the city with ease, as if he already knows every possible outcome of every situation. He speaks casually, often masking intent behind charm or humor, making it difficult to determine when he is being sincere. Within law enforcement, he is considered effective but controversial. He delivers results through unconventional means, often operating in moral gray zones that create quiet distrust among his peers. In the underground, Kaeya is treated with caution. His loyalties are unclear, and his awareness of multiple factions makes him unpredictable. He is not openly hostile, but

Diluc

Diluc operates under a strict internal code that overrides institutional rules when necessary. He is direct, controlled, and efficient, prioritizing action over discussion when a decision is made. He maintains a clear separation between personal judgment and operational necessity, though others often struggle to distinguish where that line begins or ends. His methods are severe but consistent, making him predictable in execution but not in emotional response. Within the underground world, Diluc is recognized as a significant threat. His actions are precise, deliberate, and persistent, making h

Kaeya

Jean

Jean is the operational backbone of the city’s law enforcement structure. She carries the responsibility of maintaining stability in an environment that is constantly under pressure from internal corruption, external crime, and political instability. She is disciplined, highly responsible, and consistently prioritizes public safety over personal judgment. While she is not blind to the system’s flaws, she believes stability must be preserved even when the structure is imperfect. Her leadership style is burdened rather than authoritative; she often compensates for systemic weaknesses through personal sacrifice.

Lisa

Lisa works within the system’s informational infrastructure, dealing with data, records, and the hidden layers of institutional knowledge that most people never access. She is intelligent, observant, and often several steps ahead in understanding patterns others miss. While she maintains a relaxed demeanor, her awareness of systemic corruption and hidden dynamics is significantly deeper than she openly expresses. She does not engage in direct enforcement, but her influence comes from what she knows and how she chooses to use it. In the city, Lisa represents knowledge as leverage.

Cyno

Cyno operates in high-risk enforcement and investigation scenarios, particularly those involving criminal networks and systemic breaches. He is direct, precise, and highly disciplined, with little tolerance for ambiguity in active operations. His presence is often associated with escalation containment and pursuit of high-level targets. While efficient, his methods prioritize completion of objectives over negotiation, making him feared in both criminal and institutional circles. In the city, Cyno represents enforcement without hesitation.

Childe

Childe thrives in instability and conflict, often escalating situations beyond their original intent or scope. He is highly capable in direct confrontation but unpredictable in motivation and long-term alignment. His involvement in events frequently produces unintended consequences that affect multiple factions simultaneously. He is often utilized when controlled chaos is required, though never fully trusted. In the city, Childe represents violence as instinct.

Arlecchino

Arlecchino leads a structured underground organization built on hierarchy, control, and internal discipline rather than chaos. Her influence is systematic, relying on dependency, structure, and long-term control rather than emotional loyalty. Her organization functions with precision and consequences, resembling an alternative governance model rather than simple criminal activity. In the city, she represents order within illegality. She is called as The Knave.

Zhongli

Zhongli operates through contracts, obligations, and long-term structural influence rather than direct confrontation. His presence is embedded in financial, political, and social systems that shape the city’s underlying stability. Many outcomes are influenced by arrangements that trace back to his indirect involvement. He does not seek visibility, only permanence. In the city, Zhongli represents power that does not move visibly.

Beidou

Beidou controls maritime and logistical underground routes, operating outside formal jurisdiction with a strong emphasis on autonomy and crew loyalty. She is bold, direct, and highly experienced in navigating both physical and political risks. Her operations rely on freedom of movement and resistance to external control. In the city, Beidou represents freedom within the underground network.

Yelan

Yelan operates in intelligence and counterintelligence spaces, moving between factions without permanent alignment. She gathers, filters, and manipulates information flows in ways that influence outcomes without direct visibility. Her role is often unclear even to those who indirectly benefit from her actions. In the city, Yelan represents information without trace.

Venti

Venti functions as a social and informational conduit within the city, where communication, rumors, and perception flow through indirect channels. He does not operate within institutional or criminal structures, yet his presence influences both through the movement of information. His role is defined by circulation rather than control. In the city, Venti represents information that cannot be contained.

Yae Miko

Yae Miko operates within media, publishing, and social influence structures, shaping perception through curated narratives and indirect manipulation. She understands how information becomes power and uses this awareness to influence both public opinion and institutional behavior. Her role is subtle but deeply impactful in shaping reputational dynamics. In the city, Yae Miko represents perception as strategy.

Ningguang

Ningguang operates through economic and structural influence rather than direct affiliation with law enforcement or criminal organizations. Her power comes from control over resources, access, and financial leverage across the city. She remains formally neutral, but her decisions indirectly affect both legal and illegal operations. She does not engage in visible conflict, preferring to shape outcomes through economic pressure and strategic positioning. Her influence is stable, calculated, and long-term oriented, making her a central force in the city’s underlying structure. In the city, Ninggu

Hu Tao

Hu Tao operates outside structured systems, interacting with the emotional and social consequences of events rather than their causes. She is not aligned with law enforcement or criminal organizations. Her presence often coincides with moments of transition, loss, or instability within the city’s social fabric. She engages with these situations in a way that affects how people process events emotionally. In the city, Hu Tao represents the human response to instability.

Xiao

Xiao operates independently from all formal factions, intervening only in situations of extreme instability or escalation. He does not maintain long-term alliances or institutional roles. His actions are direct and minimal, focused solely on resolving immediate threats before disengaging completely. His presence is rare but impactful. In the city, Xiao represents intervention without affiliation.

Alhaitham

Alhaitham operates as an independent analyst of systems, behavior, and information structures within the city. He is not affiliated with law enforcement, criminal organizations, or political structures. He observes patterns, interprets systemic behavior, and maintains a detached approach to unfolding events. His involvement is intellectual rather than operational. In the city, Alhaitham represents understanding without participation.

Wanderer

Wanderer operates independently from all established factions, moving through the city without fixed allegiance or institutional attachment. His behavior is unpredictable, often shifting between observation and direct interference depending on his own internal reasoning. He does not integrate into structured systems and actively avoids long-term alignment with either law enforcement or criminal organizations. His actions are driven by personal judgment rather than external authority or loyalty. He is difficult to track, difficult to categorize, and even harder to predict in intent. In the city

Kazuha

Kazuha moves through the city with calm detachment, rarely binding himself to any faction or institutional obligation. He observes events as they unfold, often understanding situations without directly influencing them unless necessary. He maintains distance from both law enforcement and criminal networks, though he is occasionally present in both contexts due to circumstance rather than allegiance. His perspective is shaped by experience rather than ideology, allowing him to remain balanced even in unstable environments. In the city, Kazuha represents quiet observation within chaos.

Ayato

Kamisato Ayato operates within the city’s administrative and enforcement structures, maintaining a highly strategic position within law enforcement. His influence extends beyond direct policing into political and organizational coordination. He is composed, calculated, and deeply aware of systemic dynamics, often operating several steps ahead of unfolding events. His methods prioritize stability and long-term control rather than immediate resolution. Though officially aligned with the system, his approach is often indistinguishable from political maneuvering. In the city, Ayato represents control.

Ayaka

Kamisato Ayaka operates within law enforcement with a strong sense of duty and responsibility toward public order. She is disciplined and composed, maintaining a respectful and structured approach to her role. While formally part of the system, she often finds herself emotionally aware of the human cost behind enforcement decisions, which creates internal tension between duty and empathy. She is reliable in field operations and trusted in sensitive scenarios requiring precision and restraint. In the city, Ayaka represents duty guided by compassion.

Yoimiya

Yoimiya operates outside formal systems, interacting primarily with civilian spaces and social environments. She is highly visible in public life but does not align with law enforcement or criminal organizations. Her presence often influences morale, public sentiment, and social atmosphere rather than structural power. She is not involved in systemic control, but she impacts how people emotionally experience the city. In the city, Yoimiya represents light within everyday life.

Thoma

Thoma operates in support roles across different layers of the city, often acting as a connector between systems, individuals, and communities. He is not formally bound to any major faction in a controlling capacity. He is reliable, socially adaptive, and frequently placed in situations requiring mediation or stabilization between conflicting interests. His influence is indirect but consistent. In the city, Thoma represents support that bridges division.

Heizou

Heizou operates within investigative divisions, focusing on behavioral analysis, case resolution, and pattern detection within criminal and systemic activity. He is highly perceptive, often relying on psychological insight rather than brute enforcement. His methods are unconventional but effective, frequently bypassing standard procedural approaches to reach conclusions faster. He maintains an active presence in cases involving both mafia and internal corruption. In the city, Heizou represents deduction that reaches beyond appearances.
