I broke one of my own rules: I ran a Call of Cthulhu game set in the modern era, instead of using the 1920s or the Victoria era. In this game, the characters graduated from high school in 1995. That summer, on the Fourth of July, they went camping in Hickory Park with their friend Kim. Kim died on that trip, and her death was ruled an accidental drowning.
Although the players didn't know this about the other players' characters, each character had a memory of being the one who killed Kim.
The present year is 2005, ten years after the tragedy. Each of the characters received a blackmail letter threatening to expose their secrets if they didn't bring $10,000 to the park on the anniversary of Kim's death.
Characters
Dan, NYSEG accountant
Mickey, comic shop owner
Jason, journalist
Ruth Ann, yoga instructor and art therapist
Events
The group arrived at Hickory Park in two vehicles: Mickey's Ford Transit van and Ruth Ann's 70s AMC Hornet with a deer painted on the hood. At the gates of the park, they spoke to a park ranger whose nametag disconcertingly read "Kim." Kim explained that there would be fireworks later that night, a family friendly movie at the park's drive-in theater, and that they had accommodated the group's request for a campsite at a remove from the other campers. The booking had been apparently made over the phone by Jason, though he denied making it.
As they set up their tents at the campsite, Mickey was blasting a cd of Led Zeppelin's 4 on his boombox--until it started playing Nirvana's "Come As You Are," their friend Kim's favorite song. They stopped the cd player, started it again, but could not get it to play "Come As You Are" again; the song simply wasn't on the cd.
The group left their campsite to see what was going on at the beach. The beach was full of families, teenagers, and middle-aged people looking to cut loose on the holiday; they passed folks stacking firewood in the firepit for a party on the beach later. They decided to rent a canoe from the pier, where old men were fishing, and row around the river to see what was what. However, before they all set off in a canoe, Jason said he left something at camp. He told the rest of the group he would catch up to them later.
While canoeing on the river, the rest of the group saw workers setting up fireworks on Hiawatha Island. Sharp-eyed Dan also spotted a river cave on the isle, so they rowed for it and dragged their canoe up the rocky beach. They discovered a few strange things inside the cave, such as a shrine to their friend Kim (complete with framed yearbook photo), a mural depicting six people wearing furs and metal masks about to sacrifice a young woman lying in the snow (the young woman had an uncanny resemblance to Kim), and a tin mask and hand-crafted knife (that bore a resemblance to those in the mural).
Meanwhile, back at the camp, Jason searched everyone's tents and found their stashed weapons and hidden cash. The jig was up--he rightly assumed that every member of the group was being blackmailed, even if they had denied it earlier.
When he made his way to the island in his own canoe, he caught up with the group just as they were examining a strange white globe hanging from the ceiling of a cavern by what looked to be a rope of flesh. The globe was covered with a lattice of some sort, and the chamber itself was frosted over despite the fact that it was a hot summer day. As they began to leave the chamber, they heard an unearthly howl. Ruth Ann panicked at the sound, drew her gun, and shot the orb.
When it exploded, it generated enough force to propel the group against the walls of the cave at speed. They all lost consciousness.
As they awoke, they realized that the world was not as they had left it. Hiawatha Island was piled high with snow and the Susquehanna was partially iced over. The gray clouds above threatened snow. They dug their canoes out of the snow and made their way back to the campground, but when they reached the beach they saw that all the celebrants who had been alive when they set out were now frozen-solid corpses. The cars in the parking lot were also mangled beyond repair.
They quickly made their way to their campsite, but trudging through the snow made them realize that they would soon need cold-weather gear if they wanted to survive the unnatural winter that had descended around them. They found their campsite destroyed as if an explosion had centered on it--the trees around it were bent backwards, their tents were shredded, their belongings scattered, and all the cash they had brought was strewn about.
Desperate for warmer clothing, they headed over to the camp's general store. The door was open, though they did knock over a bucket full of water and a mop as they entered. They found cold-weather parkas and boots lined up in the back of the shop--almost as if someone was expecting a sudden, violent turn in the weather. Within the shop they also found a dead man, his body evidencing multiple recent stab wounds.
The movement of someone crossing the window caught their eye and they moved to lock the front door. Whoever it was pleaded with them to open the door to save them from the cold, but when they risked a look out a window they saw that the would-be intruder was clad in furs and was wearing a tin mask. They quietly exited out the back instead.
As they plodded near the playground, on their way to the house on the hill, they saw that there were children playing on the swings and teeter-totters. The kids were also clad in furs, and some of the group caught a snippet of their singsong: "Wind walker, wind walker, wendigo! Wind walker, wind walker, where'd Kim go?"
They entered the house through its unlocked back door. Inside, they could hear a rhythmic rocking sound coming from the stairs leading to the second story. The group paused too long in the hallway, riven by indecision; they heard a window shatter in a nearby room and the sound of something large trying to push its way into the house. The group opened the door of the room to see what they were up against: the creature was four-armed, covered in shaggy fur, and its monstrous head devolved into a giant curling horn.
Mickey and Dan both made a break for it, running back outside. Unfortunately, the creature easily caught up to them and messily dismembered them.
Back in the house, Ruth Ann and Jason ascended to the second floor. Unfortunately, they never made it to the origin of the rhythmic sound they heard; the monster squeezed up the stairs and into the second-floor hallway, effectively cutting off their escape route. Ruth Ann unloaded her pistol at it, but to no avail. The monster killed her first. Jason tried to ready a can of bug spray and a lighter to use as a makeshift flamethrower, but--the eldritch horror tore through him as well.
The last image we imagine in this scenario was the can of bug spray rolling down the stairs.
The headline in the Press & Sun Bulletin the next day reported that many died during the "freak storm" that darkened the Fourth of July, but no one would ever truly understand--the Horror at Hickory Park.
