Seeing as your system is modified version of two open license system, is it also open license? I'd love to use a modified version of Fathom, the mechanic, but less like ethereal conceptual eldritch zones and more like accidently slipping through digital layers in an augmented reality scape.
Either way this book is an amazing read, going to send it a few peoples way, hopefully even get them to send a few bucks your way.
