>>96076090 (OP)Oh sweet Jesus is this peak “overthinking it”.
You know what every monster manual should have? Hell it should be the first chapter of the first MM:
First off full NPC stats for the following 4 NPC profiles: “Random pedestrian”, “merchant/Innkeeper”, “security”, and “local leader” followed by an easy and quick 1,2 guide for how to modify and customize each template as needed while still keeping them balanced, and maybe some guides as to what “levels”, or “difficulty” different positions/titles should be at, etc…
Because these ARE, hands down, the NPC character archetypes the players will be interacting with more than any other. They are also, typically, the most frequently improvised characters the GM is going to end up creating, So might as well make it easy on the GM and have it be front and center in the Monster Manual, and the most organized. Also, skip the “how to make narratively interesting” diatribe for these four. The PCs are already unexpectedly fascinated with the NPCs and the GM is ad libbing the characters as we speak, so just cover the stats and how to best customize them as needed and move on.
Then you can fill the rest with whatever “cool” monsters you can come up with that might spark the GM’s imagination; or vindictiveness, I don’t know.
