Dragón del sueño first appears in Volume 2 as a colossal black-and-gold draconic entity whose very presence radiates pure light and whose vertical golden pupils seem to pierce the veil of reality. Across the series it evolves from a static, awe-inspiring vision into an active, history-shaping force whose interventions ripple through the fates of multiple protagonists. Its role expands from mere spectacle to a pivotal guardian—or manipulator—of dream-realms that link the waking world with the spirit world, ultimately forcing characters to confront the blurred boundary between myth and memory.
