who is the she that gollum refers to
Shelob Shelob is a fictional giant spider from J. R. R. Tolkien's Middle-earth legendarium. She appears at the end of the fourth book, second volume (The Two Towers), of The Lord of the Rings. Her lair lies in Cirith Ungol ("the pass of the spider") leading into Mordor. Gollum deliberately leads Frodo Baggins there in hopes of recovering the One Ring when Shelob attacks Frodo. The plan is foiled when Samwise Gamgee greatly injures Shelob with Frodo's Elvish dagger, Sting, and the Phial of Galadriel.
Galadriel Tolkien describes Galadriel as "the mightiest and fairest of all the Elves that remained in Middle-earth" (after the death of Gil-galad)[1] and the "greatest of elven women".[2]
