Background

Sauron is a Dark Flame Shadow Demon born in the Great Ruins, a species associated with shadows, death, and demonic fire. He possesses Legendary potential and once ruled as a powerful Great Ruins lord, gathering followers willing to sacrifice souls or spread slaughter in exchange for power. His Shadowflame Spawn retained their minds but remained bound to their lord's life and death. 125 188 787

Before becoming Li Yao's familiar, Sauron was subdued by Kentji and imprisoned for more than two centuries. His Life Core later came into Li Yao's possession; as long as the core remains intact, Sauron can re-condense his body even after it is destroyed. 113 284 604

After his release, Sauron commonly took the form of a black cat while recovering his strength. He became bound to Li Yao through a Familiar Contract, serving as both a combat asset and a highly opinionated adviser on magic, monsters, and Main World affairs. 130 543

Appearance

Sauron's usual body is a glossy black cat, though his physical form is only a condensed manifestation of his true existence.

• Black fur and long fangs; can shrink into a miniature cat to hide in Li Yao's pocket. 130
• Apricot-yellow, vertically slit eyes that can contain violent black flames when angered. 653
• Can dissolve into or emerge from shadows. 160 653
• In battle, transforms into a Darkflame Demon King or lord wielding a Black Flame Greatsword. 603
• During his advancement, assumed the form of the Darkflame Emperor: a monarch in imperial robes and official hat, seated upon an Emperor's Carriage beneath a canopy of black flame. 693 694

Personality

Sauron is proud, domineering, and deeply concerned with his dignity. He insists on being addressed as a king, reacts badly to being mocked or ordered about, and is particularly resentful of being treated as a courier or laborer by Li Yao. 113 284 652

He is also intensely food-motivated. Souls, blood energy, Negative Energy, and thunderous power are all valuable nourishment to him; he becomes genuinely distressed when Li Yao destroys potential food sources or changes the environment of his Negative Energy Sub-World. 113 160 696

Despite his arrogance, Sauron is observant and capable of strategic cooperation. He advises Li Yao on spell combinations, magical contracts, and battlefield tactics, and he guards Li Yao during vulnerable moments. 113 238 270

His attachment to Zhao Yingluo is unusually strong. He willingly sacrificed an eye for her and reacted violently when she was later injured. 185 653
