Who told the "managers" of Moses Ascetic Order the story about Avalon???
A. Adam/ Ancient Sun God
B. Evernight Goddess
C. Roselle
Considering it was a tale and term before the "reset", and the era when the order was founded, I could only think about these... ancients.
Well, Roselle was more unlikely tho (or so I think), since he was "born" in the early fifth epoch
