I would love to bring the Thaven mechanics to upstream. I didn't even know they were supposed to be like carp people! I thought they were supposed to be like D&D tieflings. So I support this. I'm most curious about what they might end up looking like. e.g. Just humans with some gills and fins? Kuo-Toa? Spongebob fish people? Blatantly furry shark people? |

I'm putting this into a draft temporarily until I reorganize the document a bit and finish the Resonances list |

I made some changes to kind of steer away the focus of comparing them to Thaven, I think at this point they can be treated as different species with similar mechanics but with different philosophies on how to go about those mechanics. |

Loving this so much. I never got to try the downstream races but reading the whole situations you can get up tow with Resonances sounds genuinely fun for every shift. Would love to see these goobs on Upstream! |

Focused working on other projects at the moment along with irl stuff. However if anyone would like to work on this in the future I fully encourage it |


Cyprin are inspired by downstream Thaven, going into a more focused direction of being space carp/dragon people.
They’re a fully aquatic-inspired species that emphasize roleplay through Resonances, a system that guides personality and behavior without mechanical enforcement. Effectively acting as roleplay prompts.

Cyprin are humanoid descendants of ancient bio-engineering experiments that merged humanoid, carp, and draconic traits. Their defining feature is Resonance, an internal “frequency” that shapes their beliefs and compulsions, encouraging character-driven conflict and storytelling.
Mechanically, they feature distinct atmospheric interactions and a stun-based punch that sets them apart in gameplay.
Conceptually, Resonances are something I feel will be a major point of discussion. I've been very careful as to try and curate the Resonance list as much as possible and ensure clear messaging for the player that Resonances are something that should be thoughtfully acted upon. I'm happy to adjust Resonances as seen fit but I see this as quite possibly their most important feature, it gives them a unique identity and a fun twist for people who want to roleplay but aren't sure what to do, and for people who want to just have fun playing into different vibes every round.
