As far as I could tell based only on what I did for MSQ for ARR... tempered are there for the sole purpose of providing the primal with the physical manifest and providing it with the aether it craves.
How elder primals act I'm not sure (odin??). They seem to appear physically without any tempered or summoning from prayers.
King Moggle Mog as we know him isn't a primal for clarification and the mooglesguard aren't tempered but he's some form of twisted wish fulfillment manifest that craves for aether and sustaining physical form through prayer like the primals do.
Honestly, there's probably going to be a bit of handwaving going on. Even with the tempered sylphs and Ramuh, it doesn't mean one of the first reactions wasn't to do something about the tempered ones, such as putting them down. The more neutral aligned tempered sylphs just won't immediately be causing trouble.
Edit: But I have read that the idea might be that those with Echo (aka Adventurer in MSQ) is "tempered" by Hydaelyn and the large crystal thing we always see or from the Twelve.
