In the game, there were two military campaigns that left the deepest impression in Rhode's mind. One of them was when the Disaster Army retreated, leaving Lydia to withstand the attacks from the Four Legendary Generals and Dark Dragon herself, leading her to dying in the battlefield. From that moment on, Rhode loathed the Country of Light and set off the beginning of using the players' strength to change the history of the entire Dragon Soul Continent.
The other military campaign was the Diamat Campaign before it.
