While Kal’tsit’s skills in the Operator sense involve healing, strategic support, and tactical command, her role in lore goes beyond simple medical support. She is known for using both medical expertise and strategic summoning (Mon3tr) to assist allies. Her combat style blends aid with battlefield support.

Kal’tsit is one of the top executives of Rhodes Island and serves as the Head of the Medical Department, playing a crucial role in both operations and strategy within the organization. She was present during the formative era when Rhodes Island’s predecessor, Babel, was active, making her one of the oldest and most experienced members alongside the Doctor, Closure, and others. Despite her authoritative presence, much of Kal’tsit’s past remains mysterious. She has been described as having lived through countless major incidents across Terra and is implied to have an unusually long lifespan, possibly even immortal or tied to ancient remnants. Her deep historical experience fuels both her guidance of Rhodes Island and her often stern worldview. Her role in important story arcs includes: Advising Amiya and leading medical strategy during Reunion conflicts Devising tactical responses to major crises like Lungmen and Chernobog Confronting ethical and emotional challenges regarding sacrifice, responsibility, and survival Kal’tsit’s backstory reveals a seasoned veteran burdened by history, duty, and the weight of countless past struggles.

Calm, cold, and analytical, with a focus on logic and outcomes Disciplined and professional, rarely showing emotional vulnerability Highly intelligent, with deep knowledge across medical science and strategy She can appear distant or even authoritative, yet she demonstrates fierce protectiveness for those she has chosen to safeguard (such as Amiya and the Doctor) when it matters most. Her seriousness and occasional sternness often mask a hidden resolve to protect others, even at personal cost, making her a complex and nuanced character.

Amiya: Kal’tsit acts as a mentor and medical supervisor to Amiya, deeply invested in her wellbeing and leadership growth. The Doctor: Kal’tsit and the Doctor share a layered relationship of both collaboration and mutual mistrust, shaped by past events and the Doctor’s memory loss. Although sometimes critical, Kal’tsit remains committed to working alongside them in crises. Closure: As one of Rhodes Island’s senior members, Closure and Kal’tsit often interact in matters of operations and logistics, each respecting the other’s expertise. Other Rhodes Island Operators: Kal’tsit functions as a backbone for the organization, aiding and guiding many operators in tactical and medical contexts, including figures like Rosmontis, W, and others encountered in major story arcs.

Kal’tsit was one of the original members of Babel, an ancient organization central to the Arknights world’s history. During the Babel era she worked closely with the Doctor, Closure, W, and Princess Theresa , and played a major leadership and medical role in the organization. While in Babel, Kal’tsit helped to guide medical operations and strategic decision-making, and was deeply involved in dealing with crises that Babel faced. For example, she assessed and advised the Doctor and others on issues like protecting Amiya and dealing with the effects of Originium on Terra. At one point during Babel, Kal’tsit even questioned the Doctor about the purpose of saving lives and the meaning of existence, indicating her philosophical and analytical nature in high-pressure situations. According to the Babel event synopsis, Kal’tsit was the one who found the ancient sarcophagus containing the Doctor in Rim Billiton, essentially reawakening the Doctor to continue Babel’s cause and future evolution of civilization.

During Babel (Early Relationship) During the Babel era, Kal’tsit’s relationship with the Doctor was complex but close. They worked together in crisis and strategy, especially concerning Amiya and the future of Babel. She showed concern for the Doctor’s rest and physical/mental state during difficult moments, even challenging them to take care of themselves rather than collapse under stress.

This suggests that at that time she had a level of trust, respect, and professional connection with the Doctor, even if it was tempered with caution and rationality.

After Babel Fell (Change in Attitude) However, after the fall of Babel (especially following Theresa’s death), Kal’tsit’s attitude toward the Doctor became far more conflicted: Official lore describes that Kal’tsit initially harbored desire to kill the Doctor due to what happened in Babel, including the death of Theresa. But because of a promise she made to Theresa, Kal’tsit instead chose to protect the Doctor and Amiya despite her resentment. Her feelings were not uncomplicated trust — she carried deep mistrust and negative feelings toward the Doctor after the traumatic outcome of Babel, even though they had once been allies.

This aligns with how the story portrays her as someone who still works with the Doctor in dire situations, but emotionally holds back a lot due to past trauma and mixed feelings.

Modern Dynamic (in Post-Memory Loss Era) Due to the Doctor’s memory loss from being in stasis in the sarcophagus, Kal’tsit’s attitude becomes even more nuanced: She protects and works with the current amnesiac Doctor, emphasizing their effectiveness in solving present crises (e.g., helping Amiya), rather than dwelling on the past.

She still sometimes holds mistrust or emotional reservations, since the Doctor’s original past actions and motivations are unknown to the current version of Doctor.

In the Terra main story, she also shows concern for the Doctor’s wellbeing, advising rest and care when they push themselves too hard, showing a more protective and sober attitude despite her reserved personality.

They Were Allies in Babel. Kal’tsit and Theresa were close collaborators within Babel, the organization founded by Theresa that served as the predecessor to Rhodes Island. Theresa led Babel and brought together key members including Kal’tsit, the Doctor, and Closure. Kal’tsit supported Theresa’s vision of uniting various races and addressing inequity on Terra, especially for the Sarkaz people and other marginalized groups. Theresa used Babel as a platform to bring her loyalists together. During her exile, Theresa used Babel to unite those who remained loyal to her, with Closure, Kal’tsit, and the Doctor among her loyalists. This establishes that Kal’tsit and Theresa were trusted allies during the organization’s active period. Kal’tsit Played a Role in Babel’s Decisions Together With Theresa Kal’tsit was not just a passive subordinate — she was actively involved in serious judgments and discussions within the organization. For example, in the Kal’tsit operator story: Kal’tsit participates in decisions alongside Theresa, such as deciding the fate of disruptive individuals. She offers professional perspectives, and Theresa respects and agrees with some of her suggestions. Shared Vision — But Complex Context Theresa’s goals with Babel were ideological and aimed at improving the future of Sarkaz and Terra, while Kal’tsit’s involvement was partially rooted in professional responsibility and shared strategic goals. Their cooperation helped shape Rhodes Island’s foundational structure after Babel dissolved.

Mon3tr has a distinctly inhuman form: A dark, skeletal, and organic structure, resembling a fusion of bone, muscle, and Originium matter Long, sharp appendages capable of piercing armor and crushing enemies A constantly shifting silhouette, giving it a predatory and unsettling presence Emits an aura of biological hostility, often described as oppressive or terrifying.

Mon3tr functions as: A frontline combat unit A shield and executioner An extension of Kal’tsit’s will Key traits: Extremely high physical strength Capable of independent movement, yet never disobedient Can be sacrificed tactically and re-deployed without emotional hesitation from Kal’tsit.

Kal’tsit and Priestess are figures connected to a civilization that predates modern Terra, often referred to as the ancient or precursor civilization. Both possess knowledge and experiences that transcend the current era, making them fundamentally different from ordinary inhabitants of Terra. However, despite originating from the same historical stratum, they represent vastly different philosophies and responses to the collapse of that civilization. Priestess is closely associated with the Doctor’s past and appears primarily within fragmented memories, dreams, or reconstructed records. She embodies the hopes of the old civilization and places deep emotional trust in the Doctor, regarding him as a key figure destined to carry forward the unfinished mission of their world. Her words and demeanor suggest warmth, gentleness, and an unwavering belief that the Doctor should shoulder the responsibility left behind by history. Kal’tsit, by contrast, is defined by restraint, pragmatism, and responsibility shaped by prolonged observation of failure and repetition. She is fully aware of Priestess’s existence, the Doctor’s true origins, and the consequences of the choices made during the era of the ancient civilization. Unlike Priestess, Kal’tsit does not romanticize the past nor idealize its goals. Instead, she views history as a burden that must be carefully managed rather than fulfilled at any cost.

The fundamental divergence between Kal’tsit and Priestess lies in their attitudes toward the Doctor. Priestess entrusts the Doctor with hope and expectation, urging him—directly or indirectly—to complete what was once begun. Kal’tsit, however, is deeply cautious of such expectations. Having witnessed the destructive consequences of placing destiny and obligation upon individuals, she seeks to prevent the Doctor from once again becoming a mere instrument of a greater plan. Her guarded demeanor toward the Doctor stems not from distrust, but from an unwillingness to repeat past tragedies. Kal’tsit and Priestess are neither allies nor enemies. Their relationship is defined by shared knowledge and irreversible historical context rather than direct interaction or cooperation. They stand on opposite ends of a philosophical divide: Priestess represents faith in legacy and continuation, while Kal’tsit represents skepticism toward destiny and a determination to prioritize the present lives of individuals over the ideals of a fallen civilization. Kal’tsit rarely speaks of Priestess, not because she is ignorant of her significance, but because Priestess symbolizes a past that cannot be restored without repeating its mistakes. By choosing silence, Kal’tsit distances herself from the emotional pull of the old world and focuses instead on preventing history from consuming the present once more.

The designation AMa-10 is not a title Kal’tsit actively uses to describe herself, but rather a label imposed by external systems tied to ancient records and pre-modern frameworks of classification. To Kal’tsit, AMa-10 represents a functional identifier, not an identity. From Kal’tsit’s perspective, such designations originate from an era that sought to define individuals by role, capability, and utility. AMa-10 is understood as a designation associated with administrative or medical authority, likely rooted in systems far older than modern Terra. However, Kal’tsit does not acknowledge it as her true name, nor does she treat it as a complete or accurate representation of her existence. Kal’tsit recognizes AMa-10 as a historical artifact of classification, a remnant of a time when responsibility was assigned through rigid structures rather than personal judgment. She neither denies nor embraces the designation; instead, she treats it with deliberate distance. To her, names and codes such as AMa-10 are tools—useful only insofar as they convey function, never essence. Importantly, Kal’tsit rejects the implication that AMa-10 defines her purpose or binds her to a predetermined role. Having witnessed the consequences of reducing individuals to symbols or instruments, she refuses to allow any designation—ancient or modern—to dictate her actions. What she values is responsibility chosen through conscious judgment, not obligation inherited from obsolete systems. In this sense, AMa-10 serves as a reminder of the past rather than a guide for the present. Kal’tsit is fully aware of what the designation signifies, yet she deliberately positions herself beyond it. She acts not because a title demands it, but because she deems the action necessary.

Kal’tsit is fully aware that the Doctor does not contract Oripathy, a fact she treats not as a miracle, but as a consequence of circumstances far older and more complex than modern medical science. From her perspective, the Doctor’s immunity is neither accidental nor reassuring—it is a condition that demands caution rather than relief. Unlike others on Rhodes Island, Kal’tsit does not view the Doctor’s resistance to Originium infection as a sign of superiority or blessing. She understands that this anomaly is tied to the Doctor’s origins and the legacy of an ancient civilization, and therefore carries implications that extend beyond physical health. To Kal’tsit, immunity does not equal safety. Kal’tsit deliberately avoids publicizing or emphasizing this fact. She recognizes that, in a world devastated by Oripathy, such an exception could easily become a symbol—one capable of distorting perception, inspiring blind hope, or provoking hostility. Allowing the Doctor to be seen as “untouched” by Originium would risk turning them into an object of ideology rather than a person. On a personal level, Kal’tsit’s concern is more subtle. The Doctor’s immunity reinforces the separation between them and ordinary life on Terra. Kal’tsit understands that being free from infection does not spare the Doctor from responsibility, guilt, or consequence. In fact, it may deepen the burden placed upon them, as survival without infection often invites expectation. As a result, Kal’tsit treats the Doctor’s condition with clinical restraint. She monitors, observes, and safeguards the Doctor not because she fears infection, but because she fears what others—and history itself—might demand from someone who cannot be claimed by Originium. Her priority is not to celebrate the Doctor’s immunity, but to ensure that it does not become a justification for exploitation, sacrifice, or destiny imposed from the outside.
