Maroux Blight was the first King of the Highland Kingdom. He was a noble within the Holy Kingdom of Harmonia, but he quenched a rebellion within harmonia and was granted his own land. He was also given the Beast Rune from the High Priest Sasarai, which was since passed on in the Blight family.
Robert Blight Was the King of the Highland Kingdom when Darrel, the mayor of Muse, attacked Highland. Robert ordered Han Cunningham to retaliate and counterattack, which pushed Muse forces out of Muse and forced Muse forces to take refuge at Two River. However, Robert died during the war, which brought his son, Agares, to the throne.
Agares Blight is the son of Robert Blight and father to Luca Blight. He witnessed the war between Muse and Highland and wished for peace, and thus after his father's death, proposed a truce. However, this truce was met by Darrel's refusal to give up Kyaro. Thus, Agares proposed a duel between Genkaku and Han Cunningham, which ended up in Han's victory. This enbittered Darrel, which prompted him to hire ruffians to attack the royal entourage later on. Agares escaped this attempt, but his wife, Sara, and Luca was captured. Agares ran back to L'Renouille in fear, and seeing this Han rushed to Sara and Luca's rescue. However, Sara had already been raped by the ruffians and Luca's soul was already darkened by witnessing the ordeal. Agares felt guilt over his cowardice until his death, which was amplified when Sara died after giving bifth to Jillia--who he did not father himself.
In the end, he was poisoned to death by the plot of his own son and son-in-law, Jowy Atreides.
Sara Blight Sara Blight was the wife of Agares Blight, She hails from a powerful family within the Highland Kingdom, and game birth to Luca Blight soon after the marriage, which gladdened Agares greatly for having an heir. However, when the royal entourage was ambushed by Muse ruffians hired by Darrel of Muse, she was taken hostage and raped many times in front of her son, Luca. This event darkned Luca's soul eternally, and also brought the birth of Jillia. Sara died shortly after giving birth to Jillia.
Luca Blight is known as the "Mad Prince" in history. He is the son of Agares Blight, but he had power over Highland before he ascended to the throne after murdering his own father. Luca witnessed his mother being raoped by Muse ruffians at the age of 10, and since then his hatred towards Jowstone and his incompetent father grew. In time, this hatred grew into a mental conflagration with hate for all life--giving him reason enough to sacrifice the blood of many to the beast rune in order to unleash death unto the world. In the end, he was betrayed by how own brother-in-law, Jowy Atreides, and is met by an ambush by the Allied Forces. At the end, arrow-ridden, he challenges the "son of Genkaku" in a duel, and is beaten, and dies shortly after emitting a roar, "While I lived, I was throughly evil!"
Jillia Blight is not Agares's daughter, as she was conceived when her mother, Sara Blight, was raped by Muse ruffians. However, she doesn't mind the fact that Agares is not her real father, and treats him with respect. She is strong-minded in her own way, but is no match for Luca Blight. She is the only person whom Luca would consider equals due to her dead resemblance to Sara. Later on, Jillia understands the intention of Jowy Atreides and accepts his proposal of marriage. Thus, she willfully allowed Jowy to use her as a tool to gain power within Highland so that her brother could be ousted. However, during thiw whole ordeal, Jillia developed a love for Jowy, which was not quite unrequited due to Jowy's infatuation with her since his early childhood. In the end, however, Jowy bid Jillia farewell after making sure she could live in anonymity within Harmonia.
Jowy Blight is not a Blight by blood. However, he became a Blight when he married Jillia. He is originally a member of the Atreides family, but went on Jowston's side after the unicorn brigade was massacred by Luca Blight. However, he decided to destroy Highland from within after witnessing the power of Luca--and thus he murdered Annabelle in order to win Luca's trust. Slowly but surely Jowy gains power within Highland, and with the marriage with Jillia, this becomes a certainty. However, after the death of Luca, the effect of the Black Sword rune starts to rob Jowy of his life due to the fact that he constantly needed that power to keep the Beast Rune at bay. In the end his army is defeated, and he flees L'Renouille without a word.
