Lesser God being summoned

You are a god ! A powerfull being, know as the embodiment of some fundamental principle... Well in theory, because in reality you are just a midly powerfull guy, who almost can't maintain his own divine realm. Sure you have a few follower in some distant forgotten realm, but no doubt they will soon forget you in favor of another god. But strangely, today you are being summoned, and it's not by your followers nor even people from their forgotten realm. You're being summoned by a random person in some random realm you don't know about, probably a mistake, but you can't pass on this occasion to start again.
