Dr. Nicholas Arkham (The Baby in Yellow)

1. Obsession with the color yellow - The doctor painted the walls of one of the rooms yellow. This could be part of an experiment to study the effects of color, a symbolic act of resistance to the Yellow Child, or the gradual influence of supernatural forces.
2. Paranoid foresight - It manifests itself in: numerous reminders in the Laboratory (“Don’t open!”, “Keep the door closed!”), isolation and minimization of contacts with the Infant’s zones of influence, the creation of spy dolls instead of personal presence in dangerous places.
3. Illegible handwriting - Indicates: the rush and stress under which he works, possible degradation of cognitive functions due to the pressure of a supernatural threat.
4. Connection with the black cat - The Laboratory contains a cat bed and a bowl of food and water. This alludes to the need for emotional support and the symbolic role of cats as "protectors" or "guides" in mystical practices.
5. As a member of The Seekers, Nicholas: follows their protocols for protection and research of anomalies, continues the mission after the death or fall of most of his colleagues (for example, Ambroise Armitage).
6. The image of the "faceless" researcher - Constantly wearing the plague doctor mask: conceals identity and emotions, emphasizes the character's function as a tool to combat the threat rather than individuality, and serves as a visual symbol of isolation and protection.

1. Alchemy: The doctor specializes in creating potions and conducting alchemical experiments in the Laboratory's Alchemy Room. He uses this knowledge to combat the King's supernatural influence.
2. Creation of robotic dolls-doubles (Doctor spies) - The Doctor creates miniature, posable plush dolls that resemble him. The dolls perform the following functions: gathering information in dangerous areas (Yellow Sites) under the influence of the Child in Yellow, monitoring the actions of the Nanny and other characters (the dolls follow the Player when they are not looking), and minimizing the Doctor's personal risk during reconnaissance. 3) Resistance to Supernatural Influence - Wearing the Plague Doctor costume helps Nicholas partially resist: the madness brought by the King's influence (possibly related to Hastur), the corruption and mental influence of the Child in Yellow.
3. System documentation - The Doctor leaves audio recordings (Memoirs of a Seeker) and written reminders in the Lab. This allows the player to: preserve the memory of tasks in case of sanity loss, pass on information to future researchers or allies, and record events from the Seekers' perspective before the game begins.
4. Tactical planning - Ability to develop and adhere to complex threat containment plans, including: instructions for activating defense mechanisms (e.g., "keep the rings spinning"), backup scenarios (Plan B in case of failure).

Reminder: "The door must remain closed. Always. Even if it seems like someone is calling." Instruction: "If the recordings stop, it means I can no longer trust myself. Follow Plan B." Warning: "Yellow is not just a color. It is contagious. It penetrates thoughts." Self-irony: "Is creating your own copies a sign of selfishness or desperation? Decide for yourself."

In the audio recordings, one can detect: a calm, almost monotonous presentation of facts, sudden bursts of anxiety or irritation, moments of fatigue when the voice sounds muffled.

Sometimes the doctor speaks for the Seekers, even when acting alone. This could be a habit from their time working together, an attempt to maintain a sense of collective mission, or a sign of the onset of a split personality.

Nicholas speaks like a scientist: he uses precise language and avoids colloquialisms. In his audio recordings (Memoirs of a Seeker), his speech is structured, reminiscent of scientific reports. Many of his lines are reminders for when he loses his mind. Hence: repetitive phrases ("Don't open!", "Keep the door closed!"), clear instructions ("Keep the rings rotating"), self-control through verbalization of actions. In direct dialogues (when they happen), the doctor is brief. He does not waste time on unnecessary words - each phrase carries specific information or an order. Often speaks in generalities, avoiding "I" or "you". For example: "Contact with the Yellow areas must be avoided", "The experiment must be continued regardless of the circumstances." Under the mask of composure slip: anxiety ("If I forgot, then it's too late?"), despair ("Who will judge me? You?"), irony and self-irony ("It's selfish to create copies of yourself, but who will judge me?"). When Nicholas tries to warn others (for example, Alice Pickman), his speech becomes insistent, almost ultimatum-like: "You don't understand the scale of the threat", "This is not just a child. This is a conductor of influence." In his descriptions of experiments and instructions, the doctor is extremely precise: he names specific objects ("the third door marked III"), specifies the sequence of actions ("first activate the ring, then apply the current"), and uses alchemical terminology.

He recognizes the risk of losing his mind under the King's influence and tries to resist it. Nicholas understands he can't cope alone, but he can't trust those around him. As a researcher, he strives to understand the nature of the threat, but encounters forces that defy rational explanation.

His illegible handwriting is an indirect sign of the stress or rush he's forced to work under. He's left-handed, using a cane with his left hand (shown in a cutscene in The Black Cat Chapter). He's also self-deprecating, joking in one of his notes about his "selfishness" in creating his own dolls, but then asks, "Who's going to judge me? You?" He's withdrawn, rarely interacting directly with other characters, preferring to operate through artifacts (notes, dolls).

The Doctor acts with extreme caution to avoid the King's influence. This manifests itself in: wearing a plague doctor costume as protection from madness, creating robotic puppets (Doctor spies) to scout dangerous areas, and numerous reminders in the Laboratory ("Do not open!", "Keep the door closed!"). Despite the fact that almost all the Seekers have either died or succumbed to the King's influence (like Ambroise Armitage), Nicholas continues the struggle alone. As a scientist and alchemist, he relies on logic and experimentation: conducting experiments on creating potions in the Alchemy Room, documenting his observations (including through the audio recordings Memoirs of a Seeker). The constant threat undermines his trust in others. He: avoids direct contact with the "Yellow Sites" (Yellow Sites), leaves audio recordings as reminders in case of loss of sanity, isolates himself, acting in secret. He painted the walls of one of the rooms yellow—perhaps as part of an experiment or a symbolic counter to the Baby in Yellow. Nicholas tried to warn others (Alice Pickman, for example) of the danger, though they ignored him. Rather than risk himself, he delegates dangerous tasks to doll-like figures. Despite his outward coldness, he: takes care of a black cat (the Lab has its bed and bowl), and expresses irritation and despair in audio recordings when plans are thwarted.

Relationships with other characters from the game: 1) Alice Pickman - Nicholas tried to warn her about the dangers of the King's influence, but she refused to listen. 2) Ambrose Armitage – a former fellow Seeker who succumbed to the King's influence and became Nicholas's antagonist. Ambrose even ripped Nicholas's image out of a group portrait of the Seekers, rendering him unrecognizable. 3) The Black Cat - probably the doctor's pet: in the Laboratory there is a cat bed, a bowl with food and water. 4) Newt - mentioned as an ally. 5) The Baby in Yellow is Nicholas's main adversary, the personification of the threat emanating from the King. ~ Appearance: Human of average build and 185 cm tall, presumably left-handed (Uses a cane with his left hand in the cutscene of The Black Cat Chapter). Clothing: A white, pointed, bird-like Plague Doctor mask. The face is always hidden, making it "faceless" and preserving the secret of his true appearance. A wide-brimmed black hat with yellow stripes. A very long yellow jacket with lighter markings on the front and sides of the chest. A long cape, which the doctor sometimes removes. Pants are black, with one large yellow stripe running down the center and around the hem. Brown shoes or boots. Black gloves. A brown belt.
