Complete Monster: 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.
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.
Berkthgar the "Bold". Arrogant, egotistical, misogynistic and basically everything wrong with Barbarians that Wulfgar managed to mostly overcome. Throughout Siege of Darkness and Passage to Dawn, he's an ass who wants Aegis-Fang so he doesn't feel so insignificant and becomes an even bigger ass who wants to return to the ways of the Barbarians (Primarily killing people who aren't them) just because he's insecure and could never surpass Wulfgar.
