Year measurement system in Fruma?

Hi Wynncraft Forums residents

I am doing Secret Discoveries in redacted and redacted locations in Fruma and I keep seeing these denotations of years akin to BP and AP in the rest of the world. Abbreviations like NA and RA and IA and I just have no idea what any of these mean, and I looked these up on both the fandom wiki and wiki gg and I am not finding

anything of substance at all. Do we know what these things mean?

 

There’s a secret discovery in the Highlands that explains it pretty well. I don’t remember the specifics, though.
The current year is 120 IA (Industrial Age)
