Ariadne's Codex of Strings

Hello and Welcome!
We are Alvar (disheveled hair dude, left) and Marcelo (gaunt italian bloke, right), two forever DMs and former TTRPG freelancers hailing from the land of Buenos Aires, Argentina, birthplace of such celebrities as [insert football superstar] and Pope Francis, now partners-in-crime in Delaware, in the illustrious US of A.
Our Story
-
How it started
It was a bitingly cold day when, in a cozy café surrounded by flat whites and tiny pastries, we decided to turn our growing collection of homebrew rules, monsters, items, and player options into something more.
What began as a hobby fueled by passion and caffeine quickly became a mission: to bring unique, 5e-compatible content to the community.

How it's going
A year and a half later, we’re blown away by what this community has become. Thanks to the incredible support of our ever-growing audience and our amazing Patreon backers, this dream is now our full-time adventure.
Together, we’ve built a thriving hub for fantasy game enthusiasts, and we’re just getting started. We’re so grateful to have you along for the ride!
The Interns of the City of Strings!




Our Tools
Our creations are painted on a very special canvas: the Homebrewery, an amazing tool developed by the good folk at NaturalCrit. It is, almost inexplicably, 100% free. If you want to help them keep the lights on, you can do so here.
Formerly, we used latent diffusion software to create the illustrations within our books, but that has become a thing of the past. We no longer use AI in our production process, and we never will again: we now have the budget to make our products true beacons of human expression.
We already have multiple books that are 100% AI-free: Theseus' Tome of Legendary Foes, Allfather's Ink, The City of Mirrors and Alesthesian's Guide to the Exalted Wilds. Your support means we can keep expanding this list!




Community & Collaborations
Since we began our journey, we've experimented with a lot of types of content!
The support of our community has allowed us to work with wonderful artists For example, we created an entry exclusively illustrated with the dark fantasy art of the legendary Kim Diaz Holm: Allfather's Ink. On December, We released Theseus' Tome of Legendary Foes, featuring works from the amazing Midnight! Recently, we released City of Mirrors featuring incredible artworks made mainly by Mati and Nacho Lazaro, and Exalted Wilds, which includes dozens of pieces from 10 individual artists!
We are eager to explore similar projects with fellow creatives. If you would like to collaborate with this passion project in whatever capacity, contact us!
