What I wonder is why bother?
Jenred's a second tier boogeyman up north and I'm pretty sure there are individuals who act like jerks in the southern campaigns. The de Grenfelds are reliable for good lines and Marcus tried to be a diplomat with Arcachon and a Sartanian (with expected results).
When king's do something, everyone knows and remembers and can check, but you can say pretty much anything about anyone who doesn't hold a post and you can really get a good myth started.
