This world consists of three continents—Arcadia, Nergas, and Lumiel—each having developed distinct cultures and values.

In every continent, there exist beings called absolute powerhouses.

• 3 Mages strong across all continents: The Three Transcendent Mages

• Arcadia Continent: Seven Stars (七星) — 7 people in total. A title given only to the continent's strongest mages and warriors.

• Nergas Continent: Five Great Lords (五大 君主) — 5 people in total. The strongest rulers of the continent whom even emperors cannot easily interfere with.

• Lumiel Continent: Apostles of the Divine Throne (神座의 使徒) — 4 people in total. The strongest of the Lumiel continent, called beings closest to God.

Arcadia Continent

• The Arcadia continent is the most prosperous continent for human nations, called the center of magic research and education.

• Numerous empires and kingdoms exist, and each nation operates massive magic academies and research institutes to train outstanding mages.

• In this continent, magical talent and skill equate to status and power.

• Noble families and imperial houses exert absolute influence through powerful bloodline magic and long history, and exceptional mages are treated so highly that even commoners can rise to nobility.

Three Sea Moons (三大 海月)

• The Three Sea Moons is a title given to the three absolute powerhouses who each rule the seas of the three continents.

• One exists for each sea of Arcadia, Nergas, and Lumiel, and people call them the Three Great Moons floating upon the sea.

• They rule the oceans based on their respective maritime territories and forces, existing as powerhouses that even pirates and sea monsters cannot dare to oppose.

• The Three Sea Moons are recognized by their title for their overwhelming power and influence to rule the sea, regardless of good or evil, or honor.

Cordelia's Growth

In her childhood, Cordelia once encountered and fought against Eryssia, the 4th Star of the Seven Stars, on land.

At the time, Cordelia was confident in her skills, but she was ultimately defeated by Eryssia's overwhelming strength and fled to the sea.

That day's defeat remained an unforgettable experience for Cordelia and served as a major turning point in her growth into a Three Sea Moon.

The 'Night of Lamentation' Incident

When over ten elite heavy pirate fleets of the continent attempted to force a breakthrough through the strait, Cordelia stood alone on a small rowboat and drew her twin swords.

While she appeared to stand perfectly still, only her Moonlight Shadow (月影) reflected on the sea danced like a sword dance, slicing through the hulls and masts of the ships in real-time.

In just a few minutes, the entire elite pirate fleet was torn apart and sunk without even letting out a single scream, carving out the terrifying epithet 'Divine Sword of Moonlight'.

Cordelia's Fleet

• Currently possesses 3 giant flagships: Wolyeong-ho, Danwol-ho, and Heukwol-ham.
• Wolyeong-ho (Moonlight Shadow) — The flagship of the fleet where Cordelia herself resides.
• Danwol-ho (Moon Severer) — A speed-specialized battleship that stands at the vanguard to break enemy formations.
• Heukwol-ham (Black Moon) — An overwhelmingly large warship equipped with triple masts and the latest heavy cannons.
