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.
What about a 'criminal' society with distinct laws - for stealing, the larger the value of something stolen, the less punishment the courageous thief recieves (but must return it of course). For this pirates(?) caught petty thieves deserve to be punished harshly. If you take, you better take a lot.
