The Scolls have apperead in Arena, so they have been here more then Oblivion. Maybe these scrolls were not that known to the public, you could say that the Moth Priests haven't but how would the Empire know who they are? It doesn't make any sense. Anyway, that cult was in Cyrodiil, not Skyrim. People from the First Era were not unified by the Empire yet, they didn't usually leave their homeland. With this in mind it's very unlikely that she is from the First Era and knows this.
