Select a Scenario box and pull out the corresponding Event Deck. For your first game start with Scenario 1.
Ensure the cards are ordered so that the top card of the Event Decks Event 1 and the bottom card is Event 20.
Then draw and reveal the top 5 Event Cards from the Event Card deck, and place them in order in a line such that Event 1 is furthest from the Event Deck and Event 5 is the closest.
Note there are several ‘Story’ Cards dispersed throughout the Event Deck, which look different to the others.
