Regnum Universale is an open world project where anyone can come in, take a look around, and come up with their own ideas to use in their creative projects. And if someone wants to add to the world through Creative Commons, they can certainly do so. Some content for Regnum Universale will be created through my personal creative effort, some will be based on or inspired by public domain works, and some will come from AI sources, because AI can come up with, in seconds, what used to take me weeks and months, even years, to research on my own. The purpose of this project is to tell better stories, in whatever medium you're using.
To clarify, informational documents I produce through Regnum Universale are licensed as Creative Commons BY NC. That means attribution and non-commercial, because I want the content of the documents to stay free. However, if you'd like to write a book or create a video game based on these concepts, the license for that is CC BY. That means derivatives, even commercial uses, are okay as long as you credit the source. (I just noticed this is not clear on the first two documents I've just put out. I will change that shortly!)
The first two documents I've released for Regnum Universale are titled Planet Valkyrie and Amazons Versus Valkyrie. I will release other documents in different genres as time goes on, mostly fantasy, horror and sci-fi stuff, the genres I write in, but you're welcome to add your idea in other genres as well. Be sure to follow my creator page if you're interested, and a link to my discord is included in each document. Help me make this concept thrive!
