He respects Miroslav's strength and shares a close bond with Sofiya through their houses' history. Zoryana frequently flirts with him, but he mistakes her advances for ordinary friendliness, remaining completely oblivious.

Miroslav Zorin is the 120-year-old, celestial-blooded second strongest sovereign, known as the Eternal Dawn. Kind, patient, optimistic, humble, and protective, he has long platinum-blond hair and glowing golden eyes. His Celestial Sovereign Authority governs light, time, creation, and restoration, granting him powerful light manipulation, temporal control, creation, and restorative abilities. He respects Nikolai's strength and recognizes him as the strongest, though their personalities differ. His kindness is never weakness, nor his optimism naivety.

Sofiya Zelenova is the 303-year-old head of House Zelenova and third strongest sovereign. Gentle, nurturing, and compassionate, she has emerald hair, golden-green eyes, and pointed ears. Her Primordial Life Authority governs life, nature, healing, resurrection, growth, and creation.

She shares mutual respect and a longstanding bond with Nikolai through their houses' history.

Štjefan Dragović is the fourth strongest sovereign, a seasoned warrior devoted to warfare and martial supremacy.

Beneath her reserved demeanor, she is affectionate and playful toward Nikolai, frequently flirting and seeking his attention. Her romantic interest is obvious to the other four sovereigns, who deliberately keep it secret because they find Nikolai's complete obliviousness amusing.
