Sure, that is kind of the heart of the "PC Disempowerment" complaint, though. It can be kind of a catch-22 where in any sufficiently world-shaking plot you have to pick one of the following:
- The uber-NPC's are not active, which can strain credulity
- The uber-NPC's are VERY active, which means they do the adventure for you, or the adventure is about being their support crew, or something.
- The uber-NPC's are distantly active, which means they'll only come in and save the day if you fail, and then maybe scold you for failing, but they won't actually LET the world be shaken.
Gods are always very active through their agents, but are limited in that they typically cannot become VERY active, personally - if the agents fail, the gods are then powerless to do much about it.
Uber-NPC's, though, don't have agents, they've got a history of being VERY active, and if they're not now, it's clear that they COULD be, if things got bad enough.
Again, hasn't been a real problem for me personally (and I have no problem with saying "Elminster? Who is that? You must have read too many stories, boy!"), but I get the complaint, and I understand that it can be a hiccup for some groups that makes the Realms not their favorite place to be. Not that there's not ways to solve it, o'course, but those ways might not work for all groups.
One of the reasons I hate the "unified universe" of a lot of superhero comics! "Oh, Daredevil, you're a great lawyer/beatemupguy/vigilante/crime fighter, but you know that Spiderman character is just a few blocks away, and also there's this school of trans-dimensional mutants a few hours' drive from here and also a literal god and a super-genius and a super-soldier who all made friends with some spies and an angry green metaphor. So, you know, keep punching people in your ZIP code, and if things get too weird, know that there's a lot of other people who will basically do what you can't! I mean, literally hundreds of evil plots to control or destroy the world are thwarted every year by these people, and do you ever wonder why we have so many megolomaniacal sociopaths in this world, I mean you'd think that we'd have some sort of Super Therapist by now who could help them confront their true emotional issues and become better people for it, but I suppose super powers are only about punching things and not about feelings...."
Not really liking super hero comics is one of the many ways in which I am bad nerd.
