Background / History

Royal upbringing and family purge

Sif received a royal education and was taught by her father, Harold Frostmane, that her noble blood carried responsibility for the tribe’s future. Despite his hatred of southerners, Harold hired a southern teacher to teach her their language and writing. Sif expected to follow in his footsteps and eventually lead her people into battle across the snowfields 17 28.

Harold’s poisoning plunged the Cold Moon Tribe into civil war. He died in agony during a banquet, after which Sif’s mother and siblings were killed through executions and suspicious “accidents.” Her older brother Sigel forced her to flee south, ordering her never to return or seek revenge. He then used the life-consuming Blood-Boiling Berserker technique against their pursuers, sacrificing himself to buy her time 14 17 22.

Flight and rescue

Sif continued south for several days, surviving on river water, tree bark, and scattered wild fruit after her provisions ran out. Her exhausted horse eventually collapsed, throwing her to the ground. Injured, starving, and unable to move, she lost consciousness near a frozen river 22.

Louis’s Daily Intelligence System warned that Frostfrozen White Bears would eat her that afternoon. He organized a supposed hunting trip to find her, recognizing both the risks of sheltering a Cold Moon princess and the possibility of eventually claiming authority over the tribe in her name. Despite his party identifying her as a member of an enemy tribe, he ordered her taken back for treatment and supplied a rare Life Potion to save her 21 22 25.

Concealed identity and secretary appointment

Sif awakened after several days in a warm wooden cabin, still too weak to escape. Fearing that her royal identity would make her a political bargaining chip, she decided to appear obedient while studying her rescuers and looking for an opportunity to flee. She refused to answer Louis’s questions about her name and origins, tacitly accepting his suggestion that she had lost her memory 27 28.

Louis nicknamed her “Whitey” and offered her work as his secretary when she acknowledged that she could read. She accepted because the position appeared safer than imprisonment, privately treating it as a temporary survival strategy. Unknown to her, Louis already knew the broad details of her background through his Intelligence System 28.

Life in the Red Tide Fief

On her first working day, Sif accompanied Louis and recorded his activities. His persistent sword practice, the soldiers’ genuine respect, his concern for the wounded Javier, and his easy interactions with farmers challenged her belief that his kindness was merely a performance 34 35.

Visits to the Birch Sugar workshop and local school briefly lightened her mood. That evening, watching Louis train Cold Fang reminded her of her lost wolf, Solitary Moon. Louis offered her another cub, and she chose a silvery-gray, blue-eyed pup resembling her former companion, giving it the same name. Back in her private room, she wrote that Louis was a good person; although she verbally dismissed the thought, she no longer truly believed he was only pretending 36 37.

Appearance

• Hair: Silver-white and slightly tousled 28.
• Eyes: Deep blue 28.
• Skin: Pale, with the cool undertone described as distinctive to northerners 28.
• Build: Slender but visibly muscular, compared to a cheetah poised to spring 28.
• Expression: Delicate features and a guarded gaze; even when found unconscious, her face retained a stubborn expression 22 28.
• Clothing: Initially found in a badly torn fur coat; later wears an ordinary leather coat made by the fief’s craftsmen 22 34.

Personality

Sif is proud, cautious, and determined to survive. She resents being given a pet-like nickname but suppresses her anger to protect her identity. Although Sigel explicitly forbade revenge, she remains committed to avenging her family and regards her apparent cooperation with Louis as biding her time rather than surrender 17 27 28.

Her distrust of imperial nobles comes from childhood accounts portraying them as deceitful invaders and ruthless exploiters. She initially interprets Louis’s composure, diligence, and kindness as calculated disguises. Nevertheless, she observes closely enough to recognize evidence that contradicts those assumptions, particularly the loyalty he inspires among ordinary residents 27 34 35.

Beneath her restraint, Sif remains deeply affected by grief and capable of tenderness. Birch Sugar and the children’s happiness briefly soften her guarded demeanor. Meeting the new Solitary Moon brings her to tears, revealing the emotional weight of the companionship she lost 36 37.

Abilities & Skills

Literacy and Languages

Her royal education included instruction in the southerners’ language and writing 28.

• Can read, write, and record Louis’s daily activities 28 34 37.

• Recognizes that literacy could expose her noble origins, since such instruction was restricted to the Cold Moon Tribe’s nobility 28.

• Hunted and traveled through snowstorms with her former wolf, sharing its warmth on freezing nights 37.
• Begins bonding with a new cub after Louis offers her one to raise 37.
• Leaves the new cub at the training grounds initially because it has not yet fully accepted her as its master 37.

Concealment and Observation

Sif uses silence and controlled behavior to avoid revealing her identity 27 28.

• Accepts Louis’s memory-loss explanation without explicitly confirming it 28.
• Watches his conduct and relationships with his subjects to assess whether he can be trusted 34 35.
• Her concealment does not deceive Louis, whose Intelligence System has already identified her 28.
