Software: Scrivener and Obsidian. I (and others) have talked about Scrivener frequently, I wouldn't want to write without it, used it since 2010 aroundish.
Obsidian for the 'world bibles' I can throw everything in there, link the different files to each other, better than I could do in Scrivener, and also have a little database which is a newish feature, and I love it.
When I throw too many large image files into Scrivener, it takes too long to load and backup. There's the option of bookmarking (linking) the files, but I like Obsidian better for that kind of thing.
I also sometimes use a Parker gel pen.
