Chapter I: Her

Noctis Lucis Caelum. The heir to the throne of the Lucis kingdom, and he takes his duty as heir very seriously and cares dearly for his kingdom, and those who lives in it. This obviously makes him a remarkable figure for the Lucian people.

Lightning Claire Farron. A woman who was in the wrong place at the wrong time, and because of this she found herself at the other end of the stick, on the side of Niflheim: Lucis' enemy.
At this point, the woman wasn't aware of how being on this side of the war could affect her so badly, but only until she crossed paths with Mr. Caelum, did she realise.
