Frederick Harbinger

Frederick "Rick" Harbinger is the father of Joseph Carrion.

Traits
It can be presumed that, like all of Joseph's family, Rick Harbinger is a zontanecrologist. He is known to have earned a great amount of respect from his son: he is noted to have a greater ability to control Joseph than anyone else, and his voice is the voice which Joseph most trusts. He also appears to have been the person who taught Joseph to cook.

The Good, the Bad and the Mediochre
Although not mentioned explicitly in the first book, he may have been present in one of the paintings seen by Charlotte Johnson in Melinda Quinn's gallery. Joseph Carrion is the only person whom Mediochre is mentioned to have been present for the birth of, and one of the paintings appears to show Mediochre in a hospital with a couple and their newborn. If this is indeed Joseph's birth, Rick is presumably the man described as looking proud and gently stroking the baby's face.

Born to Raise the Sons of Earth
While captive in the basement of Stormhold Elect, Dreadlord Servant of the Thousand Voices, Joseph reflects that he should be home with his family by now, as he promised his father than he would help make the Christmas dinner that year.

Caught Mediochre-Handed
When ordered to stop squabbling by Elizabeth Vermillion, Joseph finds himself obeying instinctively, and reflects that his father is the only other person who ever had that effect on him.

Sent Into Mediochre-Drive
While talking with Charlotte, Joseph finally names his father as Frederick Harbinger, and mentions that he usually goes by Rick. He also mentions that Rick was a big fan of Isaiah Templeton, and that he referred to his own garage as the Frederick Harbinger Car Repository. It is also mentioned that Joseph hears Deep Ocean's telepathic speech in the voice of Rick.
