Legend
A good rule of thumb, if you really want to escape the problems you're describing while also being consistent to the books, is to involve the big NPC's only in matters that they are actually known to be involved in. That is, if you as DM want to use an established, published story arc involving one of their archenemies, then you should bring them into the equation, but if you make up something new, you have in hand an excuse why they wouldn't be involved. They can't be everywhere at the same time, and they might not even know about what your PC's are facing. Even regarding the most epic quests, they don't have to even know about them.
that sounds great, except you have to know them all, I had plans for elmunchkin and blackstaff, and drizt because I saw those coming...
I am not a fan of post time or trouble and pre spell plague realms (so 2e,3e).
What I don't want, is a book I have to study to run the setting.
I will be told I am a bad DM, and a bad fan and suck at D&D (even thought I have run this experiment before and found my group only has these problems with some settings not others)
I was running a FR game back in 3.0... before the Epic level book was even out. It was pretty simple. I kept the PCs away from the Justice League Midnight, and was only some problems (other people disliking my idea of the setting) Then came the game ending explosion...
I had they prepping an army of slave soldiers and back up by necromancers. The idea I had was anyone who died on the battle field (either side) would be raised to then fight for the red wizards. They would start with neighbor and then steam roll through the region... The PCs where the only hope, they had to find the artifact staff of life and use it to stop the evil artifact that was boosting the necro magic... or they had to steal the necro artifact, or they had to fight the army... either way this was there war to win or loose. (PCs where 10-13th level),
Then the 10th level wizard and 11th level sorcerer/ranger told me "No, we will get the symbol to handle this."
my response was "Who?"
I was told it was the sorcerer queen of the kingdom about to be steam rolled, so I flipped ot the book, and read the region write up, but not her stats... I started playing her as not as powerful as the PCs, and not having the ability to help... then BOOM... sorry she is a chosen as powerful as Elmunchkin...
well then I changed to "She is too busy, other" and it was thrown in my face that she hates they and is a good aligned ruler... so yea...
I hate settings that require this much work.
my players have in the past, and still to this day ask to play in the FR, and I have to say no now... because I can't track 100+novel characters... I just can't.
