This mini-expansion contains 9 monumental tiles, 5 new basic workers and 5 new advanced workers. It's the original extra content that was created during the KS-campaign (and given for free to KS-backers) and will be available afterwards. You add as much monuments as there are players at the start of the game. If you can create the exact shape of a monument with free squares on your board, you can claim the corresponding monument tile, which will be worth 5 VP at the end of the game.
