This is an era of bandits and monsters. The roads are unsafe, villages burn, and the emperor holds lavish parties while ignoring the suffering of the people.
This hash reality planted the seeds of revolt. Rebels gather among the teeming masses in the Capital, plotting the overthrow of the emperor. This will not be easy, and so they make dangerous moves: assassinating guards and setting fire to weapon storehouses. They grow bolder with every step.
The emperor has finally been roused to action. He calls the most disciplined and loyal warriors in his empire to him and founds a new order of peacekeeper: the Emperor’s Wolves.
The Wolves are no ordinary guards or mercenaries. The emperor’s call attracted the best of the best, who honed their blades on some of the toughest monsters in the land.
Given complete impunity to root out the rebels by any means necessary, the Wolves got to work quickly. They have captured and…received confessions from dozens of revolutionaries and their sympathizers. They are ruthless in their single-minded purpose: wipe out the rebels. This is their strength, and it may be their downfall.
As a friendly faction, the Wolves are serious-minded peacekeepers fighting truly dangerous, radical revolutionaries. The rebels will sacrifice countless innocents in random acts of terror if they think that will overthrow the emperor. The Wolves just want the Capital at peace again, and they’ll do whatever it takes to make that happen, even if they have to get a little physical now and again. They’ll have plenty of tasks for a band of PCs — spy on a group of rebels, sneak into one of their camps, destroy their supplies, etc. — and they pay well.
As a foe faction, the Wolves have grown so focused on their mission at all costs, and so convinced of both the righteousness of their cause and their own martial mastery, that they’re now extremists themselves, hell-bent on tearing through the rebels no matter who gets trampled in the process. Worse, the rebels are not the terrorist organization the Wolves paint them as: they’re freedom fighters. If the Wolves find that rebels are holed up in a tavern, the Wolves might kill every staff member at the tavern as “sympathizers.” The Wolves terrorize the people more than the rebels do, and they have to be stopped.
