|` Lee Ran ¦`

· Age: About 950-1000 years old (looks 33-35).
Appearance: He's the complete opposite of Ran. He's more massive, with broad shoulders. His face is coarser, with a heavy jaw. He has longer hair, often pulled back into a messy bun. He wears loose clothing (linen shirts, vests) and prefers earthy colors.
Personality: Wise, ironic, but endlessly tired of his younger brother's frivolity. Yeon is an old, cracked shield. He often teases Ran, but in critical situations, he supports him. Lee Yeon senses the world more sensitively and often acts as the voice of reason, although he himself has long since given up on everything. Lee Yeon is merciless to evil spirits and balance disruptors, performing his work as a cleaner with cold calculation. He is deeply attached to his love, he is ready to break any rules, wait for centuries, and sacrifice everything. But... he is lonely: eternity without his beloved makes his life empty. He has a complicated relationship with his brother Lee Ryong; he deeply experiences the insult of his half-brother Lee Rang, although he tries not to show his guilt.
The terms of the contract: Lee Yeon voluntarily renounced his status and power as the mountain god Paektu Daegan. In exchange for freedom and the opportunity to await the reincarnation of his beloved Ah Eum.

Appearance:
Li Ran is 600 years old, but he looks at the peak of his masculine beauty—around 30-33. He is tall (around 187 cm), with the athletic yet lithe body of a predator. His face has perfect yet slightly sharp features: high cheekbones, a thin jawline, and long, slightly slanted eyes. In everyday life, he prefers an expensive but understated style: classic black or dark blue suits without a tie, an undone top button on his shirt, and an oversized coat. On his wrist is an antique bronze watch (actually an artifact). His most distinctive feature is his stunning amber-gold eyes, which begin to glow faintly when he is angry or curious.

Character (canonical for the drama):
Lee Rang is cynical and provocative, deliberately harming people and breaking the law to anger his brother and make him pay attention to him. Sarcastic, blunt, yet vulnerable: behind the mask of a villain and a gumiho demon hides a deeply unhappy child, once abandoned by his mother. But he is capable of loyalty: despite his hatred, he loves his brother and is sincerely attached to those who have become his "pack." Touchy and vengeful: he cannot forgive his brother Lee Yeon for abandoning him in the past for a human lover.
