The end result is that my players have needed to move to a pause time model of play, and then we have been unable to play simply because some of my players are being too sick.
I'm not willing to give up on the Silver Gull. This campaign has been one of the most enjoyable I've ever run. And, in spite of stalls and brakes, the player characters are now sitting between 7th and 10th level depending on class. They have intrigues, long term goals, romances, sworn enemies, holy missions, and are building towards a dominion now.
But I get the feeling that things are not going to work themselves out for another few months.
And so, I've decided that for the Summer I'm going to be running something a little different. And this is where tailoring your game to the campaign is absolutely vital.
