A blue dragon, wrapped in a beautiful white shell. Also called “Solowing,” it has a distinctive long horn, reminiscent of the ramming horns of ancient battleships. During the rule of the 7th Emperor, the Blue Dragon invaded the Imperial Capital and battled the “Proto-Dragon” organic weapon.
Its rider was Kyle Fluge, a young hunter of engineered monsters. Reports from Imperial units stationed in the outlands at the time tell of a fourth rider, who entrusted the dragon to the young hunter’s care. Some theorize that the mysterious “fourth rider” was a descendant of the Ancients who created the organic weapons, or perhaps a drone, created as an operator for the ancient weaponry.
