Clarus Amicitia

Clarus is Gladiolus and Iris Amicitia's father, King Regis's childhood friend and his Sworn Shield, and a member of Lucis's ruling council. He leads the Crownsguard, a group of soldiers usually tasked with protection of the Crown City and the Citadel, and thus, the royal family. He also led the Royal Guard before its restructuring into the Kingsglaive.[1] He accompanied Regis on a trip similar to the one their children would end up taking thirty years later.

Clarus is only mentioned once in Final Fantasy XV: as they approach the Titan, Noctis tells Gladiolus he's grateful for his father after Gladiolus discusses the responsibilities of his family and its role.
