I mostly just translated Logan's open source stuff into a Troika d6-style format.
Ha, also for graduate-level Troika City work you can add Dan Sell's own city locations to your game. This is also where I learned Dan based the Troika City on Viriconium, which then Logan Knight sourced for Corpathium. Dan's location posts are not open source, so I couldn't include them in the book. But I have used them in my personal Troika campaign. Dan Sell's blog posts about the city of Troika are here: https://whatwouldconando.blogspot.com/search?q=troika+city
