A man approaches you with a proposition; a cult that seeks to only protect the weak; plots mingling and causing destruction.
Death, it seems, shall stalk the land of Merthia tonight- unless, of course, the PCs can stop it.
When the barbarian increase their raiding of Tauria, the King of Tauria decides that hiring a couple of lowlife mercenaries (the PCs) is his best option to fix the problem.
Wilhelm the Courageus they used to call him. He used to have it all. People would cheer as he rode down the street, clad in the specialized full-plate armor that the Knights of Trul wore. But no this is no more. Now Wilhelm is a nothing. People would jeer if he walked down the street, which is why Wilhelm waits in the background- until, that is, the day of his plot comes to fruition and his revenge is gained. For Wilhelm has launched a conspiracy to gain the thing that matters most to him, has brought to bear a plot through all of his means, and is a man with a plan.
In the Middle Ages, and even up to the early twentieth century, most of Europe's executioners were related: the Sansons and Deiblers in France, the Pierrepoints in England, etc. The reason for this was that, it generally not being socially acceptable to, well, kill people, executioners and their children could, generally, only marry other executioners or their children.
The parallels with massively inbred, Hapsburg-style dynasties are obvious- imagine a rather clever but politically inept satirist noting this, and being sentenced by the latter to a meeting with the former; even worse, imagine a dynasty of deranged and deformed executioners- think Texas Chaisaw Massacre with government funding.
