So, I am considering a game set in a fantastic version of Europe during the reign of Pepin the Short. The idea is that the game would have the PCs have a chance to rise to power in the momentous period of history that is the rise of the Holy Roman Empire, maybe even getting a shot at that throne for themselves. This version of history includes the existence of magic and monsters.
I am considering starting the campaign in the city of Cologne, near the borders of Saxony. Saxony would be something of a frontier the player characters could carve a domain out of, albeit with some difficulty due to the restive populace. I am also considering placing a megadungeon for the players to explore, a remnant of the Roman Empire. The primary religions are a post-Imperial Roman Cult and the local Germanic faith.
So, what do you think?
