As I spin up to self-publish more material in the new year, there are two major tracks on which I’ll be spending time and effort. One is to publish fiction. The other is to publish game-ready world-building material.

Pursuing that second goal, the first step is to design a partial roleplaying-game system that fits my preferences, isn’t under anyone else’s intellectual property, and should be relatively easy to convert to any RPG rules system a reader might prefer. That process is well underway, and the working title for the system is EIDOLON.

From the draft Introduction for the core EIDOLON book:

The word eidolon comes from an ancient Greek word (εἴδωλον) which had several meanings. An eidolon was a phantom or apparition, the likeness of a dead man that appeared to the living. More generally, it could be a figure, image, or shape, a representation of a real thing.

EIDOLON – the set of rules and guidelines in this book – is a system for quickly and consistently describing fictional characters.

Using the systems in this book, you should be able to describe a fictional character in enough detail to use it in your own creative work, or in a live-action or tabletop roleplaying game (RPG). You should be able to easily understand characters described by others using the same rules. You should also be able to convert from EIDOLON to your favorite commercial game systems, and back again as needed.

One thing EIDOLON is not – at least not yet – is a complete RPG. Every tabletop RPG provides a system for describing characters so that they can be used in the game . . . but they also include systems for designing those characters, for resolving situations in which characters must overcome obstacles, and for gaming out various forms of conflict. Although this book does include a very basic challenge-resolution mechanic, none of those other components are here. You will not be able to use EIDOLON for live-action or tabletop roleplaying without doing some additional work!

On the other hand, we plan to publish future source material for roleplaying games, based on the EIDOLON rules. These “setting books” should therefore be easy to convert and use in other, more complete RPG systems.

I’m envisioning this core book as being about 20-25 pages, to be published as a PDF on a “pay what you want” basis. At least for now, I intend to hold the copyright to the core book in my own name. As this effort matures I’ll probably release the system under some form of open-gaming license, so others can easily use it to publish their own work. Once the core book is finished, I’ll be ready to start publishing world-building material under the EIDOLON system.

My patrons will see partial drafts of the core book as I work on it, and even those at the lowest level of patronage will get a free copy of the finished product.
