Maris is a thief. A common, low down, swarmy thief. It’s not her fault she’s that way, though. She’s nice, has a sweet personality, and is most likely to talk a person into giving ‘the poor, suffering little me’ their money, due to her limited skills as a pickpoket.
What she is skilled at, however, is very, very strange for a theif. She likes reading, and has collected many old manuscripts, and is sometimes saught out for just knowledge.
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.
