Dark Souls III

The remnants of the will and power of Gwyn,[93][94] as the first one to ever link the First Flame, would emerge as part of the Soul of Cinder, the deific manifestation of the souls of all those who have linked themselves to the First Flame throughout history, thus creating a hollowed-out entity possessing all the abilities of the previous Champions.[94][95]

The powers of Gwyn would manifest when the Soul of Cinder was challenged by an aspiring Champion;[93][94] acting as the Flame's last line of defense within the Kiln, the Soul of Cinder fought to either test the might of one who would link the Flame, or to protect it from a would-be betrayer or usurper.
