One example of western incest that avoids this tired trope is Foltest and his sister Adda the White in the Witcher. Their affair happened before the events of the games since Adda died in the meantime so they serve as background to the story, but he was shown to had genuinely loved her and is overall a sympathetic figure and just king. His official Gwent card even features a true delphic statement.
