Question about The Cards Irmgard, Keeper of the Light - Do I receive 2 resources for Irmgard if my opponent receives a 3rd heroine by means of a missionary and thus removes the Red Light Tavern I built in his principality?
You only receive 1 resource, i.e., for the missionized heroine. For one thing, the loss of the Tavern is a secondary effect, and for another, the Tavern is in the opponent's principality. Irmgard, however, only compensates you if you lose one of your own expansions in your own principality due to direct effects.
Note: The Missionary card and the Red Light Tavern belong to the Age of Darkness expansion.
