The Thunder Dragon Immortal Dynasty has an extraordinary origin, being a vestige of the Black Dragon Imperial Court, one of the top Immortal Sects of the Human Clan during the Ancient Era. Its ancestors are said to have been Great Powers in pursuit of becoming True Immortals, and some even successful in becoming Immortals.
In the Ancient Era, it stood on par with the Heavenly Immortal Mansion, dominating the Human Territory North.
Although today's Thunder Dragon Immortal Dynasty doesn't possess the fearsome might of the Black Dragon Imperial Court of old, it still counts as a famous major force within the Human Territory North.
The reason the Thunder Dragon Immortal Dynasty is so named, aside from the Lei Family bloodline's proficiency in controlling lightning, is also because it has a Black Thunder Flood Dragon Monster Group attached to it.
