I mentioned this in an earlier post today, about the envelope that appears in the corner of each of these 4 cards:
According to the guidebooks, the Strongholds each have a message to deliver and to get the message, you must draw another card.
This kind of thing really appeals to me. I love when I draw one of these cards. It's like getting a strange piece of mail in the post that isn't a bill. Like a coloured envelope with interesting handwriting and a strange stamp. It's just a cool feeling.
