Dissidia NT goes onto further collusion as the goddess of science, Materia, and the god of magic, Spiritus, are the mixed remnants of both Cosmos and Chaos, and are forced to bring their warriors together in the face of an even greater threat. In the initial game the conflict is simple, but later games expand and distort this alignment, showcasing what happened before the final war between Cosmos and Chaos. The story of Dissidia is driven by a scenario of extreme conflict, a war between gods, and emphasizes Final Fantasy's themes of dualism as the clash is between a god of light and benevolence against a god of darkness and wickedness. The lead characters form different factions even within their alignment as various characters are destined to clash not only in battle, but in their motivations and perspectives.
In vein with the fighting game genre, players explore these themes individually while encouraged to play the rest of the cast to gain a full grasp of its world and story.
True to its series's namesake, Dissidia focuses on the "heart of all conflict," and gathers the lead protagonists and antagonists throughout the mainline Final Fantasy series to emphasize the core themes that tie all of Final Fantasy together.
