Who is Counselor Rawdon from Heir Apparent and what is their importance?

Counselor Rawdon is waiting for Princess Janine when she arrives at the castle. He is gray haired, wears a crushed velvet suit, and he greets her with all of the decorum a Princess should be awarded.

Janine later learns that Counselor Rawdon has been methodically cleaning out the treasury, moving the King's wealth a wagon load at a time to the catacombs near Fairfield. When Janine catches him, rather than put him to death, she puts him in charge of the pigs until he can redeem himself.
