As I always do, I’d recommend checking out this thread. It’s kept updated by Mythundis and usually lists all the active night elf guilds / events currently around:
Edit: The August Celestials are Wild Gods and as such revered by the night elves just like Ursoc, Ursol, Malorne etc., though of course they play a minor role, being mainly active in Pandaria. Monks in general don’t really take a “special” role from what I have seen. You’re just an exotic kind of warrior trained by Pandaren.
