YMMV / Four Kingdoms

• Complete Monster: Karju, the Head Boar of the Scrofa tribe, is introduced torturing an adulterous woman by shoving a hot rod into her womb before throwing her into the wilderness, where she dies. When Jabali, his then-fiancée, calls him out on this, he intimidates her before eventually beating her to force her to submit to his will until she runs away, with him giving chase. He proceeds to kill anyone who gets in his way and even stages an invasion of the Aves' city, killing even more people. He eventually has Jabali captured and brought to him, at which point he beats and rapes her. He does this again the next two days; on the third day, he grows tired of her continued "disobedience", and takes a branding iron and brands her like a wild pig. When Jabali's husband, Cal, tries to rescue her, Karju fights him, taunting and toying with him all the while, nearly killing him before Cal's horse, Xanthus, steps in trying to protect Cal only to get himself killed by Karju.
• Sweetness Aversion: The author herself jokes that Cal's and Jabali's relationship might be a bit too sappy at times. But she also says that at least Marcianus and Naja aren't gushy in their relationship with each other, so it balances out.
