The central antagonists were members of the Insidia Empire, led by Emperor Steinberg, which intended to use the powers of the Dark Dragons to take over the world and create lasting peace through oppression. Their chief knight was Klaus (voiced by Toshiyuki Morikawa), the strongest swordsman in the Empire, who was joined by Elise (voiced by Hitomi Nabatame), a woman who wielded a similar dark power, and Elena (voiced by Chiaki Takahashi), a mysterious woman with vast knowledge of the dragon clans.
