Also, if you're desperate for it to be one or the other, let the high priest of the faith issue a decree saying "Henceforth, the plural for followers of Tempus will be Tempurans/Tempurians".
I remember it was fun RP when Harroghty pointed out years ago that Tormite is an insult. Very interesting.
I know Lerytha and Ynaura call themselves Oghmans, and not Oghmanytes (although we've never said it wasn't Oghmanytes as well).
Surely there's space for everyone in FK to get on with different plurals?
It doesn't need OOC correction, just possibly an IC debate. And to give people who play characters of that faith the benefit of the doubt. If I say to a Tempuran/Tempurian "Oh, you're a Tempurian?" And they say, "Oh, no. It's Tempuran. Without the I." I'd probably just roll with it.
Give and take. Compromise. Above all, IC.
If you have knowledge, let others light their candles with it.
