YMMV / Gwendalavir Universe

• Ensemble Dark Horse: Ellana was one of the most popular characters in La Quête and Les Mondes, and later got a trilogy of her own with Le Pacte.
• Jerkass Woobie: Elea 'Ril Morienval, with a heavy emphasis on the Jerkass part. She had an awful backstory, with her being led on for years by Altan with promises he was sick of his wife (and Elea's rival) Elicia, only for Altan to abandon her when she became pregnant with their child. Elea was going to move on with her life and raise her daughter, only for her pregnancy to suffer severe complications. When she cried out for Altan to help her, he cruelly refused because it would look suspicious. When her daughter died but she survived, Elea became inconsolable and vowed revenge on the 'Gil Sayans by any means necessary, though her means eventually became siding with a race of human-eating monsters and later trying to destroy all of Gwendalavir with an Eldritch Abomination.
• Moral Event Horizon: Elea kidnapping and medically experimenting on Ewilan for months until she became catatonic destroyed any chance at her gaining any sort of redemption. Plus, the same book reveals she did the same with younger children (including a baby), and contrary to with Ewilan she didn't have any personal grievance against them. Even when she is given a sympathetic backstory afterwards, it is meant to contextualize her actions, not justify them.
• Strangled by the Red String: Mathieu and Siam. The two have absolutely nothing in common, yet Mathieu falls in love with Siam at first sight and from then on attempts to court her. Mathieu is a Non-Action Guy, while Siam can charitably be described as Ax-Crazy and shows open disdain for anyone who can't fight, yet falls for Mathieu anyways. After the first trilogy Pierre Boltero Deconstructed this aspect of their relationship, showing the pair had an extremely rocky relationship with the series ending with them broken up and unlikely to get back together due to their fundamental differences being too strong.
• Villain Decay: When first introduced, the Ts'lichs are described as the "ultimate predators", both skilled at fighting and Illustration, and Edwin is the only person to have ever defeated them. As the story goes on, he's able to defeat more and more at the same time, to the point of slaying four of them at the same time in the final book of La Quête. During the climax of Les Mondes, the last survivors of their race get slain ridiculously fast, not only by Edwin, but also by Siam, Duom, and Ellana, who each get to kill one.
