Mirne

Mirne was a Mythical Dragon, the strongest Mythical Beast obtainable on the 11th Floor. As Cha Jeong-woo's pet it grew almost as strong as the Four Legendary Beasts; its birth drew the Ancient Dragon Kalatus, letting Jeong-woo inherit the dragon legacy. Playful and open like its owner, it was hatched by Jeong-woo, who later severed their bond so it could live free.

It was believed killed when Cheonghwado used its core to heal Leonte, but in truth only its soulless body was taken—its soul had entered Cha Yeon-woo's egg, drawn by his aura's likeness to Jeong-woo's. It hatches anew with a jiao-dragon body and a demonic aura, forgoing its past life to avenge its former master; it thus becomes the Demonic Dragon, later named Nemesis.
