Each player starts with a site and 10 followers. You start in Era 1 with cards that are not as powerful, but still effective in ridding your
opponents of their followers. You can play sites, attachments, events, and reactions. Sites have abilities that can trigger when you have a certain number of followers on them. These abilities and event cards can damage other sites, also removing the followers on them. One of the other available actions is to upgrade to a newer era: there are 4 Eras and the cards in a higher Era have stronger cards.
Manage your followers, not only by recruiting more of them, but moving them to strategic sites that can enable special abilities depending on the number of followers on them. Game shines in a duel format, but can be played 2 vs. 1, and teams of 2 vs. 2. There is also a free-for-all format.
