One of the real problems over the years I've had with many old school & OSR dungeon masters is how stupid that they seem to make Cthulhu & chaos cultists. These should be some of the most dangerous foes a DM can inflict on a party of adventurers. One of the things I've done over the years is used the dungeon setting as Cthulhu or Great Old One cult temple. The adventure location becomes the focus of devotion of the cult who go out into the countryside & raid as well as pillage villages, settlements,etc. Cultists are gonna blend into the fabric of a society & community perhaps they possesses rites allowing them to throw off spells such as 'know alignment' or the like.
These folks are your local farmers, black smiths, neighbors, etc. who have been warped by centuries of Lovecraftian gods influences. They use tactics, traps, dead falls, & all manner of cunningness to deal with adventurers. Yet ever since B2 Keep on The Borderlands & the Caves of Chaos I've seen dungeon masters simply deal with cultists as another 'monster' to fight. Cultists are some of the most down & dirty bastards when it comes to tricks & traps for adventurers.
The real problem is when you've got humanoid tribes & cultists/villager NPC's working together. Then the horror can really kick in & it will appear to the adventurers that there's no place to run or hide. Tactics, spying, etc. a bevy of dirty pool is on the menu for adventurers as their every move seems tracked by evil. Make no mistake if given over to a bit of Tolkein & Lovecraft(now I know that these two authors have little in common) but combined adventure elements & events can get very wicked indeed for our adventurers.
If a DM uses orcs & Cthulhu cultists for example aligned towards the Great Old One suddenly the dungeon isn't simply a place to loot but a place of sacrifice & chaos unbound. The cult maintains the tricks & traps as a part of its gospel & I've used this quite effectively several times.
Give cultists the brains that they deserve & use every trick in the book when it comes to these NPC's. Monsters are not simply experience points but NPC's waiting to spawn campaign side quests & off shoots. So often I see DM's use monsters as fodder & not the horrors they were meant to be. Cultists are the thinking man's monster & Cthulhu cultists are the cream. Yes degeneration & madness will happen eventually in the mean time these cultists are thriving on the occult power & cosmic revelations given to them by their unholy alien gods.
