The Empress is very self-righteous and cannot bear anyone going against her wishes. Yet she cares very much for her son Enrique, and wants to expand the Valuan Empire to leave him a prosperous nation when she leaves it behind. Enrique, however, voices concern that the means that the Empire undertakes to do, by conquest, are wrong. When he voices his displeasure she will often brush him off, telling him to stop "worrying about the petty worries of the 'people'" if he is to succeed her as Valuan Emperor in the future. Thus Enrique has no real influence over Teodora's militaristic policies, and eventually circumstances lead to his joining Vyse and crew in direct opposition to Galcian's Armada.
Teodora was said to be a kind and beautiful woman once, but is now a corrupt dictator bent on expanding her power. Various in-game dialogue with NPCs explain that Valua is facing an impending energy crisis due to a severe lack of new moonstone reserves, a fact largely ignored by the otherwise ignorant upper class Valuans, who continue their shallow, mass consumption ways. Valua's massive military force did not help matters, as maintaining military power is extremely draining on any country's resources, especially in peace time. From this, it is implied that, after Enrique's father died and Teodora had to take the throne, she collapsed under the pressure of being a ruler and adopted militaristic policies as an easy way out. She listens with interest to Lord Galcian's report on the Moon Crystals and orders him to find them for her, believing that these superweapons will allow her to rule the world. However, she gives Galcian too long a leash and is slow to suspect him of treason; this lack of concern is the cause of her death, as she ultimately dies along with Admiral Alfonso and countless others when Galcian calls the Rains of Destruction down upon Valua.
- When Fina insults her during their meeting, Empress Teodora shouts "Off with her head!". This appears to be a reference to the Queen of Hearts' famous line from Alice in Wonderland.
