Welcome to Delta City!

Delta City is a Mastodon-based freeform roleplaying community based in the fictional city of the same name. The genre is urban horror/weird fiction. Everything from werewolves and vampires to Lovecraftian monstrosities to Men In Black keeping it all under wraps. Inspirations include the SCP Foundation, Mary Shelley’s Frankenstein, the Men In Black movies, Havelock Vetinari from the Discworld novels, and Anne Rice’s vampire novels. Note that while these are inspirations, players are by no means required to always be doom-and-gloom. Grimdark is all well and good, but hope exists too.

All toots on the deltacity.masto.host Mastodon instance should be in-character and should be the kind of toots that the character would actually be making in-universe.

Delta City is located in Louisiana, USA and replaces the real world city and capital of Louisiana, Baton Rouge. In-universe, Delta City is fairly large and is essentially a cross between New Orleans and New York City. It’s still the capital of the state, but also has the same sort of prestigious universities, museums, and international clout of NYC, as well as the unique culture, food and lifestyle of New Orleans. Basically, if you as a player wonder whether any given type of institution would exist in Delta City, the answer is probably yes.

Rules & Etiquette

Welcome! Please feel free to join us here, but if you do know that we ask everyone to keep a few things in mind. The following list is not exhaustive, and will be modified and expanded over time. Look, if you get it and you you're good with it, great. If you don't get it, figure it out - we can help! If you don't want to get it, maybe find somewhere else to hang your hat.

Cultivate a Safe Atmosphere

Harassment will not be tolerated, oppressive behavior will not be tolerated, and while failure to recognize the boundaries of others may be met at first with a gentle attempt to educate you, repeated failure will not be tolerated. Examples of behavior that will not be tolerated include sexism, racism, homophobia, transphobia, antisemitism, Islamophobia, fascism, and bullying. This list is not comprehensive and may be amended as needed.

Self-Promotion and Brands

Given that this is a roleplay-only server, it is inappropriate to promote websites, products, or brands that do not have to do directly with this game/instance. Promotion of fanart, fanfic, music, etc. that is directly about this game/instance is allowable, but unless it is in-character, put it behind a content warning with the tag "out of character: fanart" (or whatever it is).

Use of Content Warnings

Although this instance will necessarily be addressing disturbing or horrific material, recognize that not everyone will want to be presented with disturbing material without forewarning. As such, all pictures, regardless of what they are of, should be behind content warnings with a brief description of what they are. We also ask that any explicit material such as descriptions of sexual content, gore, or violence be behind content warnings.
