Greetings,
The question I'm talking about works either for a Comic or a Novel, I was quite curious how much dedication you put to have all the necessary infos to make your worlds work, either them be vital information that might be talked about during the plot, or even the silliest background thing that helps you to keep things organized and make sense of the whole thing.
For an example, for my Webcomic series "Stories from The Golden Garden" and it's planned following Web-Novel, among many other things that I've researched about frogs, avian, reptiles, mithological creartures, astronomy, planets, sci-fi tech, Ether etc..., one thing that I did become quite crazy about was Traveling times from location to locations, and by using england to help me with the scale and All, I've researched the timings for Train, car, and foot travel, and from them, after made the routes, end up making the Train Schedule considering also some loose minutes for delays... It took me half day to make the work on all of it... and I started the day with the revision of a chapter in mind, but it seem I got carried away.
Let me know about, what is a Detail for World building that you did concentrate the most!?
Enjoy your stay, Have a nice day!
