Welcome to the forum!
Don't hesitate to ask questions, and holy cow that's a lotta cities you're running! idk if you know about them yet, but there's a few player-run resources out there that can help you manage it all:
1.
ElvenArchitect - Has a database of all the buildings in the game, along with various comparison tools and a way to test-run any changes to your city via its City Planner
2.
ElvenStats - Lets you look up various players and fellowships and check out their score history, tournament history, and the state of their city. Includes a way to import the city it sees into ElvenArchitect so you can plan out your builds better or see what's going on.
3.
Elvenar Gems of Knowledge - Might be a little outdated with respect to events but contains excellent resources and guides for the various chapters and questlines in those chapters. Check them out once you reach Chapter 6 (Dwarves), as things stop being so straightforward in terms of gameplay (and continues to get more complicated as you ascend the chapters)
