This trio of Chrononauts cards can be added to either version of the game. Each represents a sarsen stone that was removed from Stonehenge during the Dark Ages and lost to history. Each is slightly different; collect all 3 and you can recreate a trilithon. Doing so is a bonus Mission that becomes an alternate way to win. But you can also discard a Megalith in conjunction with Sell an Artifact for a whopping 3 card gain. These cards have been kicking around in Andy’s prototype bag since 2007, when he was inspired to make them because he was asked to create a game for the Stonehenge game system.
