Babsk is a title given to a Thaylen merchant who teaches another the skills of mercantile enterprise in the form of an apprenticeship.
During the apprenticeship, the babsk retains the same legal right as fathers, until such time as s/he decides the apprentice is ready to become a merchant on her/his own. It's been hinted that some babsks exploit this relationship.
- Vstim is Rysn's babsk. He is known as a great merchant and taught Rysn the trade.
- Iyatil is Mraize's babsk, though she disguises herself as his underling.
