Said to be the mother of Gothmog, this ogress was not mentioned again by Tolkien in his later works. However, it is speculated that MERP/ICE used her name along with other Lost Tales names in order to create stats and biographies for their game. An example of this would be Lungorthin, the white balrog. It should be noted that Fluithuin mirrors a lot of traits of Grendal's Mother, in the tale of Beowulf--a poem that Tolkien knew about and liked.
