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.
The PCs are invited to play in lumberjack games. They must see how quickly they can cut down a tree, how quickly they can use a great saw to cut a wheel from an already dropped tree, and must stay on top of a floating log while a lumberjack tries to roll the log to make them fall in the water. The winner gets beer and pancakes
