Branwen

Branwen is a "Dragon Descendant," one of the most noble and rare beings in the Continent also known as the "Holy Dragon Warriors" for serving the dragons in the ancient times. Unfortunately, she has become a gladiator slave and is forced to fight for her life against other slaves and monsters in the Swamp Witch's Arena. Ordered to fight in exchange for the life of her dragon ride (Usher) that was captured along, Branwen has been through numerous fights to the death. Her current master is the Trainer Dogura. For a bit of prestige and cheap wine and also to be praised by the beautiful witch, the goblin slave trader will make Branwen fight again today without mercy. However, the pride of her lineage won't allow her to die easily.
