Scylla as she appears in the movie.

Scylla was the evil ruler of the Odaku. Her personal Dragon was named Slann. She made deals with Stendhal to free him in exchange for the Shadow Dragons to give magical powers to the weapons and armour of her army. She was an imposter, who banished the true heir of the Odaku throne, Gorhagar. Her goal to begin the Metal Ages and conquer the western territories brought the Odaku into conflict with the allied armies of the Draigar, Norvagen, Ferroch, and Fyren. She was killed by lava.
