After each player has taken their turn, and players resolve any “follow” actions, the Night King Evokes Terror (noted by the icon next to each die slot on the Action Mat). This occurs following each player’s turn.
Evoking is similar to plotting, but the Night King steals non-player Power Tokens from House Mats to place in his Terror Pool. Reveal the top card from the Plot Deck, and for each the shield on it, resolve it as follows:
• One of the 4 non-player house shields in the game: Take 1 Power Token from that House Mat (if available) and add it to the Terror Pool.
• ANY other shield: Move 1 White Walker from the White Walker Mat’s pool to the Terror Pool. If there are not enough White Walkers in the pool to move, the Night King immediately gains for each Shield that did not result in moving a White Walker (this is marked on the White Walker Mat).
After Evoking Terror, place the card into the discard pile.
