After the players' actions are completed, first resolve any White Walkers in the Terror Pool: for every 2 White Walkers, the Treaty must move 1 Power Token of their choice from the Treaty’s Ally Pool, moving tokens into the Terror Pool. Afterward, return all White Walkers from the Terror Pool back to the White Walker Mat.
Then players check alliances, comparing Ally Tokens in the Treaty's Ally Pool with tokens in the Terror Pool. The side which has more of a single NP house's tokens gains that house's Shield Token. If there is a tie for tokens, the Treaty ALWAYS gains the alliance. Note that the Iron Throne counts as a wild Terror Token if the Night King controls it (meaning it counts as one of any NP house). If the Night King wins an alliance, he terrifies that NP house (see Terrified Houses).
