About the adventure

Welcome to CAIN, where exorcisms are bombastic, the horror is visceral, and the darkness is always hungry. If Chainsaw Man, Persona 5, and Jujutsu Kaisen haunt your dreams, you will feel right at home. If you love modern horror and games like World of Darkness or KULT, this table was built for you. New player or seasoned veteran, all are welcome here. No prior knowledge of CAIN required. Just bring a love of monster hunting and a willingness to stare into the dark. Experienced System knowledgeable Admin will assist. "Kill Sin. Lie to God. As Above, So Below." - CAIN's Motto Beneath the crushing weight of human existence lies a black psychic miasma, a roiling sea holding every memory, want, and desire humanity has ever produced. Most never notice it, a passive undercurrent beneath what we call reality. But the sensitive can see it, and what lives inside it. They are called Sins. Not merely wants or actions, but entities born from trauma in the lives of the psychically gifted. Left unchecked they eat flesh, taint everything they touch, and kill thousands in their wake. The secret organization CAIN exists to stop them, and you are their weapon. You likely joined as an adolescent, flagged for your psychic potential. Inside every exorcist lies a sin-seed, a paranormal growth waiting to bloom into something monstrous. CAIN recruited you to wipe your stain clean through service. They don't see you as part of their organization. They don't even see you as human. In this campaign you serve under CAIN's arm Temerity rather than Castle. First-time exorcists face a survival rate in the low 40s. Your team is one such group. Armed with the 12 Blasphemies, psychic powers capable of tearing reality apart, you will hunt what hunts humanity. A minimum of 3 sessions is required to give your character a proper story and, if needed, the send-off they deserve. Ten sessions is the booking maximum. The question is whether you survive. Or whether the exorcist becomes the Sin.

About me

Hello! I am Yuthika, but you can call me "Fey." I've been a forever GM since age 12 with nearly 34 years at the table. Raised in Asia, my first RPGs were Call of Cthulhu and Sword World, and Japanese tabletop culture shaped everything about how I run games. I play rules-second and players-first, with a strong Rule of Cool philosophy and a focus on immersive, player-driven storytelling. I run a wide range of systems, from indie darlings to classic staples, and I'm passionate about bringing lesser-known games to new players. Just because I don't have a system listed doesn't mean I don't know it. You can always ask! I'm also a TTRPG designer and co-creator of Visions of Suaykalpa, an upcoming Southeast Asian mythology RPG launching on Kickstarter this December.

Character creation

Creating your character

This game is new player friendly at my tables. It is open to all experience levels and I fully intend to support new players from start to finish. Meant for 4-6 Exorcists. 3-4 Hour Game Sessions. 30 mins table chat split into a pre game check in and a post game Roses and Thorns, 2 15-minute breaks and 3 hours of actual play. Basically a 3 hour game with breathing room. Character creation will be handled during Session 0 which will not be counted towards your booking of 5-10 sessions. This is due to the nature of the trigger warnings and associated dark themes and to ensure all players have a firm understanding of what they are getting into. This game is not for everyone, but is open to all. Characters will be created per the official rules in CAIN 1.3 and will start at base level. Players are encouraged to support the author if they wish and buy a copy of the game. Support Indie Devs. No books are expressly off limits, and no character archetypes are limited. Character creation should will be a highlight of the game as it will truly introduce you to the world of CAIN, it's antagonists and its dark horror vibe. If you have a favorite fan made Sin you wish to face or Blasphemy you wish to use on your exorcist, please expressly bring it to me. If it is not broken, I will likely allow it. Think a mix of Chainsaw Man, Persona, and Jujutsu Kaisen, add a little Cabin in the Woods, some Nightbreed by Clive Barker, and you are starting to zero in on the vibe.

The current party

No specific party composition required: all Exorcist types welcome. This game is open to new and experienced players alike. The only requirement is a willingness to engage with dark, intense content and a commitment to table safety and respect for fellow players.

What to expect

Preparing for the session

Players should have a Foundry VTT account and Discord as that is how the game will be run. I pay for all hosting and supply all other needed materials. Please send a friend request to me on Discord only after you are a confirmed seat, unless you have questions that need answering. Note that any attempts to circumvent StartPlaying.Games will result is a table ban. You are welcome to ask questions but not to skirt the rules. Again this is a new player friendly, learner friendly campaign. If you have been interested in trying the world of CAIN, then this is a table for you. CAIN runs on a Forged in the Dark system, meaning player characters are handled primarily through playbooks initially but can very much choose things from other playbooks as well.

What Yuthika "Fey" brings to the table

I bring to the table hosting, character voices, ambient music, high grade maps, and ambiance to help immerse you i the dark and gritty world of CAIN. I am also a teaching Admin (GM), which means I firmly believe in helping on board others into systems and settings. Do not feel afraid to come in with only a rough idea of what the game entails. I will gladly help you through all of it.

Homebrew rules

I do currently use both CAIN: Leviathan and The Odysseus Protocol, these are officially supported materials and the only current additions to the base book being used in this game as a default, however, the CAIN subreddit has a ton of great player made additions from Sins to Face to Blasphemies for your character's powers, if you find one you like, let me know.

Safety

How Yuthika "Fey" creates a safe table

Your Safety Matters CAIN deals with heavy, disturbing content and I take player wellbeing seriously. This game is based around Traumatic Events creating Sins from Psychically gifted individuals so Trauma and dark themes are baked in alongside body horror and personal horror. Before we begin, we'll use Lines & Veils, you'll have the opportunity to set hard limits on content that should never appear at the table, as well as topics you'd prefer kept off-screen rather than depicted directly. These are respected without question, no explanation needed. If for some reason your lines and veils preclude you from playing CAIN I will speak to you about what can be done or accept your departure with grace. My table operates on an Open Door Policy, this means that if at any point the content becomes too much, you are always free to step away, take a break, or leave the session entirely without judgement. Real people always come before the game. During our 3-4 hour sessions I'll do regular check-ins to gauge how everyone is feeling, especially after particularly intense scenes. If things get heavy, we take a break; no pushing through. At the end of every session we close with Roses & Thorns, this is a chance to share what felt great and what didn't land, keeping the game a collaborative, comfortable experience for everyone. After the session, I'll also follow up with a private message to check in individually. Sometimes things hit differently once you're off the game and decompressed, and I want everyone to feel they have space to raise anything they didn't want to mention at the table. This is a dark game, but it should never feel unsafe. When in doubt, just say the word. Again this game is not for everyone but in the right hands with the right group it is a memorable experience. The extensive trigger warning list below is not all the things that WILL be in every game session, it is all the things that COULD be in a given session depending on the hunt and the Sin your team is sent to execute.
