Arwen, also known as "Undómiel (Evenstar)", is an Elf from J.R.R. Tolkien's The Lord of the Rings. She is the daughter of Elrond and eventually the wife of Aragorn. She is beautiful, gentle, and wise, or at least intelligent, as befits an Elf. While her character is not given as much in-depth description as some of the other members of the cast of LotR, she is definitely a sympathetic character. Which is why the way she is characterised in badfic is so inexplicable.
