I want a good name for a psychic entity that is going to crawl into an archaeologist's mind in a Victorian Call of Cthulhu game I'm planning. I'm thinking it's one of those things that can briefly manifest in the physical world as a horribly tentacled monster, but normally it just curls inside his id, driving him toward ever more gruesome crimes.
So what would you like to see in a cosmic horror villain? Name, appearance, traits, etc. Any idea is welcome. Go nuts!
The name of my entity is She Who Waits in Darkness. Essentially, it a giant disembodied eyeball with various green tentacles oozing mucous and slime everywhere.
The way she gets into the Id is through picture of a woman that has a "strange look" about her. At first her victims will be curious about the woman in the picture, thinking that they know her from somewhere, but couldn't remember where.
They will search her out, find clues that lead the PC's to some sleepy Victoria-era town/village and go about looking for her. Of course, as they get closer to She Who Waits in Darkness, they get mental impulses from her as if she's in pain, or angered, or lustful, or some other kind of feeling. This feeling turns the victim into anger and they get false "clues" that someone was responsible for killing the poor girl woman in the photo, so the victim lures the "murderer" and kills them. Of course, they realize the "murderer" had accomplices, so they look for them too and kill them.
After several murders, the victim will be drawn to a manor where they must open a portal via terrible magic and then be drawn into She Who Waits in Darkness' realm only to be eaten, because all the raw Id and anger tastes so good.
Now, here's the types of adventures you can run with this.
1. The victim is an NPC and friend of the PC's. The PC's have to track down clues as to what happened to him, connect him to the murders, and then discover the terrible horror as it eats their NPC friend.
2. The victim is actually the PC's and they will believe that they are tracking down vile cultists whom they got to take justice in their own hands. After killing innocent people, they may have a moment of clarity just before conducting the ritual and realize that they are murderers. They are faced with the dilemma to either deal with the cosmic threat (and get eaten) or they turn themselves in, or high-tail it out of there.
Here's a couple of twists too.
The town is a gate for the entity. An old manor, when the stars are right and the proper rituals invoked, allows humans to travel from this world to She Who Waits in Darkness' nightmarish realm. Now She Who Waits in Darkness has many of her pictures scattered about and murders happen all the time in New England, but her victims always find their way to this town (i.e. think of Silent Hill), find the book of rituals, and conduct the magic to travel to her realm.
She has devoted (and quite insane) followers whom She will not eat because She needs at least some help to ensure that her victims come to her after they had their fill of murder and carnage. During lean times though, her followers will invoke the rituals and gladly sacrifice themselves to her (after all, they are completely nuts). These followers will help the PC's find "murderers", get the PC's out of jail, and so on. They will be very good allies when needed, but when the PC's have their moment of clarity or were investigators to begin with, they find them outright hostile.
The followers in the town are people of position--the mayor, the head of the town council, the police chief, Mrs. Gotthrieb, the local gossip and most wealthy widower (six times!), an editor of the local paper, etc.
