The Endless Road
The Divine Empress rules from the Imperial Capitol to the west. The Road leads there, or so you've been assured. Her Knights and Priests and Tax Collectors can be found upon the road in the villages of the realm.
You are traveling in answer to the Empress's summons. As Her servants you have an obligation to tend to Her subjects along the way should you have the time and ability. You know that She will judge you based on the quality of your service to Her and to Her people.
You don't really remember if you've ever met Her before… It's probably unimportant.
