Insomnia, the Crystal, and the Chosen King
Before jumping right into the events of Final Fantasy XV, it’s necessary to understand why our protagonists are at the center of attention. If you can look past all of the magical swords, powerful gods and goddesses, and the insane popularity of Cup Noodles. Noctis is the prince of Lucis and he resides in the royal city of Insomnia. But there’s much more to it than that.
Insomnia is protected by the king’s endless vigil, guarding the last Crystal known to exist. The Crystal is a gift from the gods from a time long forgotten, categorized as mere myths and legends by those who know no better. It has the power to repel darkness and to keep those who use its power safe. Since it is the last remaining one, it serves as a bastion for the last of those who don’t want to be conquered and enslaved by the Niflheim. Regis uses the power to keep a magical barrier around the city until the Chosen King rises and uses the Crystal to banish the darkness once and for all.
That Chosen King happens to be none other than Noctis who, after falling into a coma, is visited by an Astral and selected to be the Guardian of the Light. There is an encroaching darkness, and the Astrals (which are essentially gods in Final Fantasy XV) need someone they can imbue with power in order to push it back. It’s no secret that he is destined to be this royal champion of light, and that makes him a target which must be protected at all costs.
