Guardian (Final Fantasy X)
From Final Fantasy Wiki
In Final Fantasy X, a Guardian is a warrior tasked with protecting a summoner during their pilgrimage across Spira to defeat Sin and bring the Calm. Most summoners traveled with one or two Guardians, though some, most notably Yuna, were protected by upwards of six. The earliest known Guardian, as well as the first to defeat Sin, was Lord Zaon, the lone guardian of Lady Yunalesca, the first High Summoner. Another duty of the guardian was to offer themselves during the final summoning to calm Sin and ultimately become the new one, although it would seem this was unknown to the summoners and their guardians prior to their potential meeting of Yunalesca.
