A couple questions before I get to work on my CS (thinking of a young soldier who ended up being the official military authority on board the ship, just because everyone senior to him has died of the plague):

What are the symptoms of the plague? Are our characters immune to it, or are we just lucky enough not to have caught it? Does the city we departed from have a specific name, or am I free to give it one? 

Thanks! I'm looking forward to this.
