The eighth of the Ten Great Nobles, it has no castle and wanders the realm like Karin. Since time immemorial it has been spotted at battlefields and over time developed a reputation as a premonition of impending death. Grail took an interest in the unique nature of the Guork's mana, performed some research on it and then nominated the flying rock to the position of Great Noble. Nobody opposed the nomination, so Guork received the title despite its nature as a floating rock. The final boss of Karin's route, Guork is revealed to be the spirit of the beast which originally inhabited the flame tree and ravaged the demon realm until its soul was split from its body and sealed by one of the previous monarchs. It has wandered the realm since searching for its body, once reunited it plans to destroy the demon realm. Guork killed Karin's younger brother Izayoi eons ago and Karin was initially unaware that her fellow noble was the nemesis she had been searching over millennia for. As the original master of the flame tree, Guork can interfere with Primtine's control of the castle, which in gameplay terms forces players to engage in battles with whatever enemy is on the tile at the present point. It is eventually destroyed for good when Karin wields 幻斬り to strike it down in her route. She is the only one able to stop it as the rock's hardness renders it almost invulnerable against all attacks, even going so far as to seriously injure Volja and Ardbelt when they are duelling.
