Starless Night

Starless Night is the second book in the Legacy of the Drow series by R.A. Salvatore. It was later reissued as book eight of the Legend of Drizzt series.

"The Underdark. A place of brooding darkness, where no shadows exist, and where Drizzt Do'Urden does not wish to go. The noble dark elf must return there, though, must go back to find his friends in the gnome city of Blingdenstone, and on to Menzoberranzan, the city of drow. Only then can Drizzt discern what perils might reach out from that dark place to threaten his friends in Mithril Hall."

Summary
The title, Starless Night, refers to the unlit nights in Menzoberranzan, where Drizzt travels to Menzoberranzan to keep the drow armies from going after his friends and invading Mithral Hall. He gives the statuette of Guenhwyvar to Regis and tells him not to tell anyone where he went. When Cattie-brie later has suspicions and questioned Regis, she was skeptical and decided to follow Drizzt. When Bruenor finds out from Regis, he goes into deeper grieving, already saddened by the loss of Wulfgar.

Drizzt goes first to Blingdenstone and stays for a short while after being unwillingly involved in a raid and captured. There, he meets up with Belwar Dissengulp, and old friend, before leaving. Then in Menzoberranzan, Drizzt is able to disguise himself for a little while as a guard to gain entry into the central districts, but is later found out. He is captured and taken to Matron Baenre's dungeon and introduced to six Baenre nobles, before being brutally tortured by Vendes Baenre, the chief torturer who earned the title Duk'Tak (Literally, Unholy Executioner). Meanwhile, Cattie-brie uses the magical mask to disguise herself as a drow priestess. She teams up with Artemis Entreri, who has gone to Menzoberranzan in the protection of Jarlaxle, and frees Drizzt. Drizzt kills Vendes out of sheer hatred, then later fights Dantrag Baenre, who was considered the second-best to Zaknafein, so he wanted to kill Drizzt because he was Zaknafein's son and protege, to come out of Zak's shadow. Drizzt defeated him and obtained the speed-enhancing bracers that he wore, while Cattie-brie took the sword Khazid'hea "Cutter" from Dantrag and narrowly escaping the Baenre complex. Artemis Entreri escapes as well, and goes his own way, while Cattie-brie and Drizzt return to Mithral Hall to meet Bruenor with apologies.
