Elbereth

Elbereth is ths Sindarian name of the Vala Varda. Her name comes up at various times during The Lord of the Rings, usually in a song or invocation. The Elves whom Frodo Baggins, Peregrin Took (in the novel), and Samwise Gamgee meet in the Shire are singing a song in her praise. Frodo Baggins calls out to Elbereth when he is attacked at Weathertop, and Aragorn refers to her name as "deadly" to the Nazgul.
