These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Matron Yvonnel Baenre (who first appears in The Dark Elf Trilogy), the de facto ruler of the Drow nation Menzoberranzan, is also the most evil Drow yet seen. Yvonnel Baenre keeps the city in its dark, chaotic state while destroying Drow houses she judges have outlived their usefulness. Her own children live in fear of her, and when dealing with her most hatred rivals, the Oblodras, Baenre annihilates their House, sending every inhabitant, even the slaves, to the Abyss to be tortured eternally. Baenre's ultimate goal is to conquer the dwarven kingdom Mithrill Hall, and for this end, she has enslaved the soul of its first king for two thousand years. She also utilizes her Illithid ally to forcibly and painfully mentally torture and devour the minds of those she wishes to interrogate while allowing her children and house to torture those who catch their eye. when she assaults Mithril Hall, her goal is nothing less than the deaths or enslavement of all in her path.
Vendes Baenre, one of Yvonnel's daughters, is just as fiendish as her mother and more monstrous than almost any other Drow. Known and feared for her sadism and penchant for Cold-Blooded Torture, Vendes delights in getting her hands on any possible victim without regards for their crimes. Vendes ruthlessly tortures Drizzt Do'Urden and reveals her reputation in Menzoberranzan is well deserved. Vendes is also known for torturing luckless male drow and turning them into agonized statues to adorn the paths of the drow academies as a reminder to what happens to those who forget their place.
Fridge Horror: We've seen what Wulfgar went through for 6 years. Now consider what Matron Baenre did to K'yorl. She sent her to the same demon that tortured him -Errtu—only K'yorl's been tortured for 127 years and counting.
Entreri and the drow woman Jerlys act quite flirty toward each other too during their brief encounter. Despite the fact that she thinks he's excrement and wants to dominate him, and he ends up killing her.
The Scrappy: Let's just say that there are a lot of readers who don't like Catti-Brie very much, especially Wulfgar fans who feel that he was killed (albeit temporarily) just so that Catti-Brie could become Drizzt's love interest.
