This first post is an index for a project I'm posting as much to motivate me to actually keep working on as anything, so that I can give the first post a unique post title without changing the thread title.
Part 1: Introduction and Idea Barf (okay, maybe that unique post title wasn't worth a double-post).
Part 2: Spreadsheets and Basic Structure
Part 3: Key Items and Themes
Part 4: Lore and Proto-Maps
