Nebimus

Long before the Twelve Legendary Dragon Knights became the legends of Isteria, there existed Nebimus a forgotten legion of eight hidden entities who answered to no kingdom, no god, and no throne.
Their purpose was to guard the truths that history was never meant to remember.
Among them walks Soujin, the Black Dragon Knight, the only Dragon Knight ever chosen by Vyralith, the Banished Dragon an ancient dragon erased from every sacred chronicle.
Cast into the endless void for defying the Celestial Dragons, Vyralith's name became a forbidden whisper, spoken only by those who sought power beyond fate.

Yet the bond was never broken.

Through the darkness, Vyralith's will flows into Soujin, making her the unseen blade of Nebimus.
Neither here nor conqueror, she exists to awaken when the balance of Isteria is threatened by forces older than dragons themselves.

To the world, Nebimus is a myth.

To the Dragon Knights, they are a warning.

For when the Banished Dragon stirs once more, the hidden legion will step from the shadows... and the fate of Isteria will no longer belong to kings, dragons, or gods.
