The Mage is the name given to a suspected entity responsible for otherwise inexplicable measured fluctuations in the local age of souls. At present this fluctuation is suspected to be evidence of advanced tempumancy originating from the future and impacting the present.

If he or she exists, he or she is likely known in his or her own time as the Archmagus, a title inherited after surpassing the prior Archmagus in total demonstrated proficiency across various schools of magic.

The Mage is the son or daughter of Diane. The era they have come to preside over is known to Arcturus Ansel (the sole survivor who still lives on Mersia) as the Silent Age.
