Yeah it's a little shady that titles are pretty much "sold", makes it seem like the King is corrupt, but it's not like this never happened in our real world too
Ennoblement is the conferring of nobility?the induction of an individual into the noble class. Depending on time and region, various laws have governed who could be ennobled and how. Typically, nobility was conferred on individuals who had assisted the sovereign. In some countries (e.g., France under the Ancien Regime), this degenerated into the buying of patents of nobility, whereby rich commoners (e.g., merchants) could purchase a title of nobility.
