I just thought about something...

well, the whole thing of them branching off is probably the other way around, similar to how the languages were originated from one thing, but became another. Flamekeepers could have eventually evolved and changed into the F/Ps and Archers...etc.

(For you people that dont know, each language was really based off of one base language, which became some of the languages we know today. French/Spanish from Latin, English and the modernized German from German...etc.)
