Looks like there are a lot on DMs Guild - but would love to hear someone's specific recommendation to winnow the wheat from the chaff...So Paizo has created "bestiaries" of NPCs for their Pathfinder RPGs - if you need bandits, assassins, evil wizards, etc. Is there anything similar for 5e?
(The Monster Manual has some - but there's not enough for a humanoid-centered campaign.)
