Harmonia

Harmonia is the last dragon and the leader of the Sea of Time, a hidden successor of the Black King who guards the door of darkness.

Biography

A supposedly dead dragon guards darkness

The Summer Queen recognizes Harmonia's scent after Yeon-woo's encounter with her, undermining the belief that the dragon was dead. Harmonia later reveals herself as a successor connected to the Black King and as the doorkeeper stationed at the door of darkness. Yeon-woo judges her command of darkness superior to his own at that stage, which makes passing her position a problem of authority and control rather than simply defeating another large creature. (Chapters 540 and 579–597)

The Sea of Time loses its leader

Harmonia emerges from the abyss in a dragon form vast enough to dominate the scene and identifies herself as the last dragon and leader of the Sea of Time. She restrains Laplace and continues the organization's plans after Allforone, maintaining pressure on Yeon-woo's side through the end-of-days conflict. That campaign does not survive intact: by Chapter 707 the narrative states that Harmonia is dead and that Yvlke is the only leading enemy left. (Chapters 625–700 and 707)

Appearance and personality

Harmonia can appear as a colossal dragon whose scale is compared with the enormous forms surrounding the abyss; her presence alone overwhelms nearby observers. She is severe, authoritative, and controlled, correcting Laplace rather than indulging his behavior. Her willingness to remain hidden after being presumed dead also shows patience and strategic secrecy. (Chapters 579 and 625–641)

Abilities and powers

Harmonia manipulates the Black King's darkness with greater refinement than Yeon-woo initially possesses and can operate at the door connected to that power. In dragon form she releases an oppressive aura on a vast scale and opens or traverses abyssal space. These abilities support her role as a gatekeeper and leader, but the scoped text does not establish that every Black King technique belongs to her personally, and her death confirms that succession does not grant the main ego's final authority. (Chapters 579–597 and 625–700)
