As such, he is known as the "Immortal Shogun" to many and is known as the "Marshal" by Noctis and his group due to his status in the Crownsguard, the military unit that protects Insomnia and the Citadel, and thus in turn the royal family. Throughout his life, Cor survived countless battles, earning him the moniker "Cor, The Immortal". He dedicates his life to serving Lucis.
