There are strange things going on in your basement laboratories. They keep calling up for more barrels of quicksilver, or bits of your hair. Well, it's all in the name of progress. They're looking for a way to turn lead into gold, or at least into something better than lead. They're also looking for a universal solvent. If they manage that one, you will take whatever they use to hold it in and build a castle out of it - a castle that can't be dissolved! Now that's progress!

This expansion adds new Kingdom cards to the Dominion board game, and requires a copy of Dominion or Dominion: Intrigue to play.
