Cats! The Conspurracy
hosted by staff GM Laura
For millenia, the Earth has carried a fiercely guarded secret: human beings are not the only intelligent species roaming its surface. Moreover, not only is it not the only one, but it’s neither the first nor the brightest... because that place belongs to cats! Forget everything you’ve learned in history books and think you know about cats, and discover the greatest secret of all.
Cats! The Conspurracy is a complete tabletop roleplaying game. You play awakened cats with great psychic powers, whose ancestors created mankind! And your mission is to protect the Conspurracy, the veil cast over human reality in order to make them think cats are only pets.

Vaesen
hosted by staff GM John
In dark forests, beyond the mountains, by black lakes in hidden groves. At your doorstep. In the shadows, something stirs. Strange beings. Twisted creatures, lurking at the edge of vision. Watching. Waiting. Unseen by most, but not by you. You see them for what they really are. Vaesen.
Welcome to the Mythic North – northern Europe of the nineteenth century, but not as we know it today. A land where the myths are real. A cold reach covered by vast forests, its few cities lonely beacons of industry and enlightenment – a new civilization dawning. But in the countryside, the old ways still hold sway. There, people know what lurks in the dark.
They know to fear it.

Cthulhu Dark
hosted by community GM Jim
Cthulhu Dark is a tabletop roleplaying game of cosmic horror, in the style of H.P. Lovecraft.
It's about the things we fear, amplified until they are unbearable. It's about stories that genuinely creep you out, not well-worn tropes and creatures you've seen hundreds of times before.
And it's about bleak horror, in which humans are powerless when confronted by hyperintelligent alien horrors. You can't beat them. You can't fight them. You can only watch, run, hide and fear.
If you love Cthulhu games already, then this is Lovecraftian horror at its most intense. If you're new to them, then Cthulhu Dark is a great place to start. You'll enter a world of stories that are both terrifying and terribly human.
Omnihedral is looking for community game masters who are willing and interested in participating in the store's Weekly One-Shot program!
First time GMs are also welcome to apply (we are happy to help you out)! These games are rotated weekly, on Tuesdays.
If the GM is able/willing and there is enough player interest, we also like to do encores of the One-Shots on the following Wednesday (the next day). Games tend to be on a monthly theme, and we are looking to have 1-2 Guest GM One-Shots per month. You will be invited to collaborate on theme TTRPG choices, and availability, in a channel on our Discord server.
We, historically, try to offer narrative or low/0-prep games for these one shots, or character pre-generated games, where we provide everything needed for players to show up and play without session 0s.
If you are interested in running a game with character generation done by Players, we can facilitate early-sign ups and set up threads in our Discord to help coordinate that effort, though!
These One-Shots are held in the Caverns, there are TV's, name placards with dry erase markers, pencils/pens, and we are happy to loan any dice necessary so that Players do not have to bring anything.
