Ludwig was placed in Tilley by his mentors in Adestry. His lack of people skills make him difficult to work with, so his mentors decided that putting him in charge of young kids might help speed up the process. Ludwig of course hates this and plots everyday how we can get out of the shit hole that is Adestry, and will use people (the players) to further that goal down the line. How? This could be by framing them for something and appearing to be the one who "fixed" it, or by using them "to show his social skills and team work effort" (not really) to fix a bigger issue plaguing Tilley.
