Crownsguard

Crownsguard is an elite group of soldiers usually tasked with the protection of the royal family of Lucis in Final Fantasy XV, although their focus is changed right before the start of the game. Notable members include Clarus Amicitia, King Regis's "shield" and bodyguard; Gladiolus Amicitia, who serves the same role for Prince Noctis; and Cor Leonis, a legendary soldier known as the "marshal".
