Lightkeepers

(Apologies for the low quality, I am not experienced with fandom)
Lightkeepers are people, who can seemingly be of any aspect that wield the power to create light from their souls, this light has the power to dispel Voidfog. they are usually taken by the Central Authority to work at a Lighthouse for the rest of their life, it’s unknown if this damages their health or lifespan, Lightkeeping magic appears to be a Regalia since you cannot gain it and are born with it. From what it seems either the Radiant Tones is the source of Lightkeepers’ powers or Lightkeepers are the source of the Radiant Tones’ power, however Lightkeepers are capable of teaching others the power to use the Radiant Tones, albeit not to the extent they themselves can become Lightkeepers themselves. So far we only know of one Lightkeeper, Viqh, who was taken to the Eastern lighthouse, but refuses to run it out of spite, and has taught Klaris the radiant tones, which she engineers to make Castle Light’s soul barrier, the Lighthook, and the Dawnwalker Oath.
