Fire Emblem Fates is split into three story paths. Conquest is one of the two base stories, the other being Birthright. The other story path can be bought digitally at a discount through the in-game store. The third story path is Revelation, a DLC that was released later. You need to be have completed Chapter 6 in either game to access the other stories and DLC. Conquest is the hardest of the three paths, having reduced ability to grind experience from maps, tougher mission objectives, and giving less money and experience for those missions.

This chapter of Fire Emblem Fates follows Corrin, a young royal caught between two warring kingdoms. Born into the peaceful realm of Hoshido but abducted as a child and raised as a cherished member of the shadowy kingdom of Nohr, Corrin is drawn into open war when a mission erupts into bloodshed and they are reunited with the Hoshidan family they never knew. Blessed with the power to become a dragon and wielding a legendary blade, Corrin is forced to choose a side. In this path, Corrin remains loyal to Nohr, the family who raised them, choosing to fight alongside their adoptive siblings under the iron rule of King Garon. Rather than abandon their homeland, Corrin resolves to change Nohr's cruel and warlike ways from within, hoping to steer the kingdom toward a better future, even as that choice pits them against their own blood in a brutal conflict.
