Aeons

Aeons are unknowable beings from beyond the veil of space and time and exist outside the borders of any sphere. Architects and observers, Aeons watch over specific worlds and even individuals with great interest,  exerting considerable influence on both at a simple thought. While someone will likely never know they are being watched over by an Aeon, they exhibit some remarkable benefits, most notably they're high resistance to mind altering magic.
Few know of the existence of Aeons, even among the divines, knowledge of them is scarce and they are rarely mentioned by any god, if it all.
