I would guess that the 8th Phenomena is related to Promestein with the keyword "mage" playing as a metaphor for science, since there was this one saying that in the future magic and science would be indistiguishable from each other.

It also fits the theme of the "All-Knowing" and "reached the truth", since she is part of the Seekers of Truth.
