Once a proud dragon that held firm beliefs, Duma was quite loyal to Naga, serving as the leader of the military that protected her, but due to his banishment alongside his sister, he came to bear such a deep hatred for Naga that he had humans construct a tower to face Archanea, the land Naga ruled. Despite all that happened, Duma does hold love for his sister, as he never once turned Falchion against her, with his desire to seal Mila with Falchion was also done out of love.
