The entity has consumed the small town of Riverdale and has brought it into the fog.

RIVERDALE

The entity has consumed the small town of Riverdale and brought one new killer; The Gargoyle King and two new survivors; Jughead Jones, and Ethel Mugg's, and two new maps, and realm; Sunnyside trailer park, and The Sisters of Quiet Mercy, in the realm of Riverdale.

The Gargoyle Kings perks “Pulling the Strings”, “Obsessive Games”, and “Dead Light” allows you to slow down the survivors generator project and gain more positives from chases.

Jughead Jones's perks “Strength in Numbers”, “Rule Number Four”, and “Never Give Up” allows him to save his fellow survivors and keep them in the fight for as long as possible all the while benefiting yourself. 

Ethel Muggs perks “Call for Help”, “Checkmate”, and “Wronged” allow Ethel to keep the killer busy and stay strong while doing it.

Maps: SunnySide Trailer Park, and The Sisters of Quiet Mercy

The one to the left is what I thought the Sunnyside Trailer Park map would look like in shape and to the right is what I thought the Sisters of Quiet Mercy map would look like in shape. The green means that it's an outside part and the red means it's an inside part, the exit gates are blanks. 

THE KILLER: The Gargoyle King

Power:

 The Hallucinating Mist; the hallucinating mist inflicts a new status effect the fear status effect. The fear status effect at tier one makes the survivor hallucinate skill checks that are quite obviously fake, tier two fear will give you the blindness status effect, and last but not least tier three fear will give you the oblivious status effect. In order to get rid of the fear status effect you can go around the map and find a campfire which will get rid of all three tiers of your fear status effect after 10 seconds, the campfire becomes inactive for 120 seconds after someone has used the campfire and gotten rid of their fear status effect. The fear status will not go away passively. 

Perks:

“Pulling the Strings”

Every time you hook a survivor Pulling the Strings activates, after you regress a generator it stays regressing for 20/30/40 seconds, and if a survivor starts working on the generator Pulling the Strings time pauses until the survivor completes the generator or leaves it causing the generator to start regressing again. Pulling the Strings has a cooldown of 60 seconds after you regress a generator. You can only use Pulling the Strings on one generator at a time.

“And every cult has its king.”- Jughead Jones

“Obsessive Game”

You become obsessed with one survivor, Whenever you chase your obsession Obsessive Game starts to charge up, it takes 60/50/40 seconds for Obsessive Game to fully activate, once Obsessive Game is active one random survivor becomes marked, this survivor cannot be your obsession. A survivor will stay marked for 30/50/70 seconds, once that timer is up that survivor becomes your obsession. You can only be obsessed with one survivor at a time.

“I’m going to be with Dilton now. We both flipped the coin. He was scared to ascend, but I’m not.”- Ben Button

“Dead Light”

Survivors in your Terror radius gain no great skill checks and the regression penalty for failed skill checks are 1%/2%/3% worse than normal. You kick generators 30%/40%/50% faster.

“Who doesn’t want to be king? Who doesn’t want blood sacrifices in their name?”- Chic

THE SURVIVORS: Jughead Jones, and Ethel Muggs

“No serpent is left for dead.”- The Serpents

"Never Give Up"

While you are 16 meters from a hooked survivor the survivors hook timer is paused for 26/30/34 seconds.

“That’s the common misconception about fairy tales. They very rarely have a happy ending.”- Jughead Jones

Ethel Mugg's

Perks:

“Call for Help”

Whenever you are hit by the killer and put into the injured state your aura is revealed to all other survivors for 30/40/50 seconds, all other survivors while healing you, they gain a 100% healing speed boost while Call for Help is active.

“In all seriousness though, who cares about anything? We’ll all be dead soon.” - Ethel Mugg's

“Wronged”

After you are hit by the killer all stuns last 10%/20%/30% longer at the expense of a 3%/2%/1% decrease in generator repair speed.

“For your crimes against the town of Riverdale, for everything you and your family have done, and continue to do, we find you guilty. Your sentence is this.” - Ethel Mugg's

This all I have so far but I don't have any lore on how they were sucked into the entity's realm and I went with Ethel because I really, really didn't want to do Veronica or Betty, but honestly it wouldn't be a Riverdale DbD chapter without Jughead.
