Hey (: I'm a huge ff13 story line fan, but I still don't understand the term 'nova chrystallia' before I thought it was another name for that trilogy but they say ff15 is also one of those
Nova Chrysalia is where LR:FFXIII takes place, after Valhalla merges with Pulse.
I think the term you’re thinking of is “Fabula Nova Crystallis,” which includes the Final Fantasy XIII trilogy, Final Fantasy Type-0, and Final Fantasy XV. The name refers to the mythology (the Crystal Legend, Fal’cie and l’Cie) that all these games have in common.
Originally, they were going to have XIII, XIII Versus, and XIII Agito, which were all different interpretations of the same mythology. But of course that changed. XIII became it’s own trilogy, Agito became Type-0, and Versus became XV. They still have the same mythology though.
I hope that answered your question. uwu
