Either:
1. Elrond's elvish wife from Lord of the Rings
2. The title of what is widely reputed to be the absolute worst example of smutfic ever written in any fandom. Celebrian, the fanfic, gives an "
alternative" account of what happened to Celebrian while she was held captive by Orcs. For those who really want to know, it involves many, many descriptions of orcish genetalia, as well as the supposed protagonist's "lavender labia" (a good indication that the "author" has never seen a woman's bits before). Strapped-on dildos inserted into the anus,
beastiality, blow-jobs and
watermelon sized breasts are also involved.
