Kingsglaive: Final Fantasy XV (2016)

Within the enchanting realm of Lucis resides the precious Crystal, the last of its kind in the world, coveted by the formidable empire of Niflheim. Leading the defense of Lucis is King Regis, who commands the elite fighting unit known as the Kingsglaive. These skilled warriors harness the king's magic in their valiant efforts to safeguard their homeland. However, as the relentless forces of Niflheim advance, King Regis is presented with a harrowing choice – to wed his son, Prince Noctis, to Princess Lunafreya of Tenebrae, a captive of the empire, and relinquish Lucis to Niflheim’s rule. Despite the king's reluctant acceptance, it becomes apparent that Niflheim will employ any means necessary to achieve their sinister ambitions, leaving only the Kingsglaive to thwart their ruthless pursuit of global supremacy.
