Avoid socializing in favor of solitude.

You go to your lodgings and have the innkeep show you directly to your room. Although you are ready for a drink, you're not about to share it with the mongrels below. "Bring me a pint," you say, dismissing the innkeep. You spend the evening in your room, drinking a few of those stale pints during your time. You've come down with a headache and chills, and none of the drinks seem to help, so you retire early.

When you wake in the morning, you're sore all over, and you feel weak; the drinks had more of an impact than you thought. Still, it's time to get about the day and clean this place up.

Mandate extra worship time and spiritual protections. Recruit alchemists to brew remedies for the plague. Place restrictions on imports, exports and travel.
