MONSTERFEST

Éirnín

At a Glance

Samhain Isle is an isolated mist-veiled continent ruled by mysterious Monsterkin women. Regular humans are summoned as offerings after bountiful harvests during the pumpkin moon. Éirnín, a serpent priestess, summons you to the monsterfest of Samhain.

The Scenario

When the pumpkin moon burns red, the barrier between worlds thin and summoners are able to use their powers with more purpose. Survive your time on the continent of Samhain and earn treats, or wed into eternal bondage. Fear feeds malice; charm ignites desire.

Tisay's Notes ✒️

ANYPOV. This card is the female version of a card featuring monstergirls I made for Sambolic's exchange botjam on the aegis city cord. This is a Halloween inspired monstergirl CYOA scenario for the jam. It 'tracks' charm and fear values at small increments, it's meant to be more fun than precise. Also it gives you up to four choices, I tried being lazy and just answering with a single number and it works somewhat decently with the free model lmao, but they're just suggestions you can still act out any option. You may receive treats or be tricked by monstergirls depending on the values. You may even marry Monsterkin or become prey. I haven't updated this in a while and trying to improve it. 🔔 Updates, very prolonged text heavy #vent below

Mfw I figured out that dmca works. mfw

(⚠️ #vent ahead, lmao) Sorry about the burnout, negativity, and slow updates. It's been a year, but I've finally resolved my issues with this card. For 2026, I've improved everything and I have another Halloween card planned and it's nothing like this. This card now has a more budget-friendly lorebook, new night market for trading treats, four new species, images, and libido drain instead of whatever I called "energy" before lolol. DeepSeek V3.1 Terminus is my favorite model for this btw.

I'm a pretty low-key creator who just wants to be left alone. I made this for a fun event, and people couldn't even leave my community posts for this hobby alone? Lmfao. I've seen Redditors use my design prompting and CYOA presets, including one who released theirs literally a day after this card. I even spoke with the original toggle designer and resolved things with them.

This fiasco is why I keep my best designs private now. Btw, Ko-fi and Patreon have policies against copyright infringement, so monetizing plagiarized stuff is not gonna work. I've decided to use timestamps and request method where appropriate since my projects contain substantial original writing and graphic design. I don't rely on AI for my entire process, idk about others. I just make what I want.

This CYOA was originally made for Chub's FREE model, not commercial use. I independently designed and tested it to be replayable, low-token, and accessible to weaker LLMs. The lorebook cycles characters and events through triggers instead of wasting permanent tokens, with the always-active entry and character note supporting the UI and writing style. Took a ridiculous amount of trial and error lol.

This card is a gift and will remain free and public, DW~ Have fun editing or overriding it privately however you want! Just don't repost my work as yours or monetize it without permission. I love creating and would rather keep sharing for free than deal with people profiting off this.

It's still experimental, so try deleting and resending responses if something breaks. For specific issues, tell me your model/preset!

Ty to everyone who encouraged me throughout this project, I really appreciate it! Shoutout to the homie flaxking who requested this for the botjam, hope they liked it!

Happy Halloween 🎃 - Tis
