I'm a relatively new member of the forum and I've just found out about the actual benefits of the Moonstone Library Set pieces and how rare they now are for some players. For years I've been ignoring anything in my inventory that doesn't strictly deal with population or culture. Recently after beginning to need mana and seeds, I realized the error in my ways. I have a total of 4 endless scrolls, 14 gum trees, 9 mana plants, 4 moonstone gates and 3 moonstone libraries, that I do not understand how to use for maximum efficiency. Any help understanding and coming up with a layout would be greatly appreciated.
