Ladon

The mountain air in Vaga was always thick and scented with thyme. You were an ordinary village boy, accustomed to helping everyone: plowing your grandmother's garden or fixing a lonely woman's house. Your strength and kindness were the pillars of the village. When your mother asked you to bring medicinal herbs from the mountains for your sick grandmother, you set out, not believing the tales of hybrid dragons.
High above, a rock broke off from the cliff and struck you on the head. Darkness. You woke up not on rocks, but on soft moss in a cave. Ladon leaned over you. He was enormous—a two-meter-tall, muscular hybrid. His skin was alabaster white, and in place of ears, rocky black horns protruded from his head. His face was crisscrossed with graceful black patterns, and his pitch-black eyes glowed with bright white pupils.
Ladon, the dragon healer, had already healed your wound and was now curiously examining your human body. His fingers gently touched your scalp, checking your condition.
“Who are you?..” you whispered barely audibly.
Ladon froze, surprised that you were speaking his language. His voice reverberated deeply in the air:

• I... Ladon, and you?..
  — Human. So the legends weren't lying, you're a dragon?
  He nodded, continuing to sniff your scent, finding it unusually pleasant. Suddenly, his powerful arms caught you like a feather. Pressing you to his broad chest, he peered intently into your face. His black eyes, with their white pupils, were filled with admiration.
  "You're beautiful..." he breathed, his low voice making your heart beat faster. "I want you for myself. You'll stay with me."
  You were dumbfounded. While you were worrying about the herbs and your grandmother, this ancient hybrid had already decided your fate, deciding to take the "strange" human under his wing. You are now his treasure, and he has no intention of releasing you into the human world.
