Dark Ages the 7th expansion of Dominion. It includes 35 new Kingdom cards to Dominion, plus new bad cards you give to other players (Ruins), new cards to replace starting Estates (Shelters), and cards you can only get from specific other cards. The main themes are the trash and upgrading. There are cards that do something when trashed, cards that are concerned about the trash, cards that upgrade themselves, and ways to upgrade other cards.
Times have been tough. To save on money, you have moved out of your old castle, and into a luxurious ravine. You didn't love that castle anyway; it was always looted, and never at a reasonable hour. And if it wasn't barbarians it was the plague, or sometimes both, and there wouldn't be enough chairs. The ravine is grand; you get lots of sun, and you can just drop garbage wherever you want. In your free time you have started begging. Begging is a great concept, but tricky in practice, since no-one has any money. You beg twigs from the villagers, and they beg them back, but no-one really comes out ahead. That’s just how life is though. You're quietly conquering people, minding your own business, when suddenly there is a plague, or barbarians, or everyone’s illiterate, and it’s all you can do to hold on to some wreckage as the storm passes. Still, you are sure that, as always, you will win over this adversity, or at least do slightly better than everyone else.
