------------------
In Dissidia, Firion travels with Cloud, Cecil and Tidus. As the three each go their separate ways to fight their own personal battles, Firion begins to question his reason for fighting. His one true desire is to end the war and create a peaceful world free from tyranny and oppression. Firion carries a wild rose with him, his wish to see them bloom freely a symbol of the world he hopes to see. During the game, various other characters learn of Firion's dream and share his hope for a peaceful future, including Cosmos herself.
