For future reference or whatever, when you have a game with events on cards like this, it's often helpful to list each card with any additional detail needed in a section of the rules. FWIW.
When I first started writing the rules, it was my intention to put that very section in the rules appendix. However, when I did the cards, I had no idea what to write in those pages that was not already on the cards. (Well, except for the Campaigns, which are in the playbook.) If something did come up, I tried to reword the event so the something went away.
