Square Enix released quite a few direct feed screenshots of its upcoming CG Movie Kingsglaive: Final Fantasy XV, that will intertwine with the game, also showing relevant characters old and new.

We also learn more about their background:

Nyx Ulric is the protagonist and a member of the Kingsglaives elite unit. When he was just a boy he was saved by king Regis during the war, so he feels a debt of gratitude. He's an excellent fighter, and has a high affinity with the magic of the royal family.

Lunafreya Nox Fleuret has the ability to talk directly with the gods, and she's a priestess of the Kannagi, responsible for the purification of the energy of the world. She still cherishes the moments she spent with Noctis during her childhood. She is supposed to be wed with the prince in Altissia, and she is going to the metropolitan area of Insomnia to reach an agreement with the king of Lucis.

Drautos is the general in command of the Kingsglaive, stern both with others and towards himself, he reached his position due to his hard work. He's Nyx's master in the art of battle.

Libertus Ostium is Nyx's best friends, hailing from the same town. He has a bright personality, but he has also an emotional and stubborn side.

Luche Lazarus after having become one of the leaders of the Kingsglaive, he has earned the trust of the veteran members.

Crowe Altius is blessed with special abilities, and one of those able to wield powerful magic. She's native of Lucis' frontier, and grew up as an orphan. She thinks of the members of the Kingslaive as her family.

You can see the rest of the screenshots below. It'll definitely be interesting to see if, besides Luna, any of the newly announced characters will appear in the game as well. They definitely seem to be an interesting bunch, especyally Crowe.
