It’s still a touch shonky which is why I haven’t made it public but you can find it there at tabletop.trilogy-rpg.com feel free to use it but make sure you keep a back-up of your character sheets just in case something goes wrong!

The main thing I need to do is document it to make it clear how it works, but if you’re trying to figure it out for yourself the most important thing to do is to ask yourself “how would a madman do this?” and then you’ll probably be on the right path!
Importantly creating a scene requires a location and the characters to add to it, NPCs and opponents are optional, but you have to choose the location to start with.
