Christopher P. Corpse

"Ah, me...I wish I could stay, but I have unfinished business to attend to..." -The Ghost of Sir Chris P. Corpse while leaving King Valence behind
(also Christopher: struggles to leave because he loves Valence way too much)
Sir Christopher Polonius Corpse, also called Sir Christopher, Sir Corpse, General Corpse or Chris P. Corpse (by multiple people) is one of the many ghosts in the SHTM series. Unlike many other ghosts in the series though; he isn't an animatronic like his friend Valence, and is an actual ghost/full-bodied apparition. In life, Christopher was a warrior in Orken's royal army; along with King Valence. He also was king there; before he had stepped down/retired to spend more time with his family (nieces and nephews). Unfortunately, like Valence, he did not have any children.
Some people think that Valence and Christopher are a couple; but Bluey (the creator) proved this wasn't true; "Chris and Valence just trust each very much; and Christopher was usually a skittish person, but Valence helped him come out of his shell. So much so, when Valence had died and first became a ghost himself, Christopher wanted to help him on his ghostly journey, much like he had helped him when he was alive."
Background:
Christopher's background is very secretive, as the viewers of the series and/or readers of "A Fallen King" barely are given details of his birth and/or childhood. It can be concluded, however, that due to his similar accent to Valence, Christopher was born in England, back when matriarchy was at it's prime. His mother and father were both royal matriarchs (king and queen) as well, like Valence's parents. However, in large contrast to how the von Ornell Family ruled, the Corpse Family ruled with an iron fist, bettering the community for their loyal subjects. Christopher was largely inspired by his parents as a child. He was even sent to prestige schools, due to his parents' large amount of wealth, as they wanted the highest level of education for their son.
Despite being enrolled into the most divine and luxurious school life, it wasn't all that it was meant to be. Due to Christopher's middle name being "Pelonius", his general peers and bullies made fun of him, calling him "Chris P. Corpse" as a joke. However, Christopher did not take well to his classmates' humor, and had no real friends due to his name. He was the type of kid that "stayed in the shadows", as Bluey calls it.
It is unknown when Christopher's parents passed away, but soon afterwards, Christopher had to move out on his own. Inspired by his late parents, he aspired himself to become a king, as the rest of his family did. He had settled himself into a small city near England called Orken, that was in desperate need of a ruler. In a heartbeat, Christopher obliged to the role, immediately seizing the throne, and crowned as Orken's first ever king. It is assumed his rule was much similar to Valence's, but less progressed. He had ideas to reform the city, but none of them went into full effect. He never married, and is confirmed that he had many brothers and sisters. Christopher treated his own nieces and nephews as if they were his own children. He also seems to be in good spirits with his siblings, even after his death. 
Appearances:
At first, Christopher isn't mentioned THAT much, only referenced and mentioned by his companion, Valence in ParaMollnan, claiming he was a great warrior and a good friend.
In A Fallen King, the viewers get to know how Valence had met Christopher, and how he witnessed his death in the Battle of Rawenwall. Afterwards, two years later, Christopher's ghost pays an otherworldly visit to his former warrior and friend before passing; warning Valence that he will die soon to prepare him for his demise. Christopher does not know how he will die just yet, but he claims he can "feel it in my gut.". Along with that, Christopher's ghost becomes pain-stricken as his voice wells up with sorrow as he describes how much he has missed Valence since his passing; trying to roam the Earth to constantly look for him (dear God; they are NOT a couple). He was also forced to roam the Earth as a ghost because his body still lay upon the very battlefield where he had lost his life, and instructs his only friend to bury him near his own castle which he once had ruled, and stick his own sword into the ground near his body as a marker, to make people remember his heroic bravery and actions whilst in battle. Valence claims that he feels terrible, as he was busy with other things, leaving Christopher's decaying body on that very battlefield for two years, and was scared that his ghost would swear a divine vengeance against him for doing so.
