At the beginning of each Act other than the first (Act I), a Storm is spawned on the Game Board. The size of the storm (number of hexes) is equal to the new Act, so when Act II begins, a two-hex Storm is spawned; when Act III begins, a three-hex Storm is spawned, and when Act IV (the endgame) begins, a four-hex Storm is spawned. Players choose the location and orientation of the Storm when it is spawned; the orientation stays the same for the duration of the game, but the location changes.
During the Enemy Phase, all Storms on the Game Board are moved based on Fate Die rolls. A Fate Die roll of 0-4 means the Storm moves one step towards the player with the First Player token, while 5-9 means it moves one step in any direction the players choose.
Storms cover the spaces on the Game Board world map where the Storm is located, no matter whether it's land spaces or sea spaces, and have the following attributes:
Enemy Phase
The game alternates between Player Phases and Enemy Phases. In each Enemy Phase, the following things happen, in this order:
1. If the Elder One Arises effect is triggered, that happens first.
2. If the Elder One is in play, it activates next.
3. If there are any Storms on the Game Board, roll the Fate Die for each Storm to determine how it moves. On 0-4, the Storm moves one step towards the player with the First Player token; on 5-9, the Storm moves one step in any direction the players choose.
4. On Deck enemies activate. If there are multiple such enemies, the players choose the order in which they activate, except that when one enemy on a player's ship has activated, the other enemies on that player's ship must activate before activating enemies on other ships.
5. Enemy ship activation. Activate each enemy ship once. If there are multiple enemy ships in play, the players choose the order in which they activate.
6. Advance the Enemy Agenda two steps, plus one more step for each player. If the Enemy Agenda advances beyond the end of its track, it wraps around to the first position, and causes the Enemy Discovery token to advance on the Discovery Track.
7. Pass the First Player token clockwise.
Then, the next Player Phase begins.
