I just realized the main enemy that we will be dealing with in Dragonflight will be the Primal Incarnates.
These are dragons, that embody a certain element, who are hostile to the other Dragonflights, so they were locked away. Sounds familiar?
The primals in FF14 (even the name is the same) are summoned entities, incarnations of a certain element, often popular summons from other Final Fantasy games, who in some cases have been imprisoned by certain races, because they were too dangerous or because they wanted to harness their energy. One of the most famous and most powerful ones, Bahamut, is a dragon. As well as Shinryu, who was summoned in Stormblood.
Even with the comparison not being 100% accurate, I'm getting the feeling they took this idea from Final Fantasy.
