fanlisting

A fanlisting is simply an online list of fans of a subject (in this case for natalia l.k.lanvaldear) that is created by an individual and open for fans from around the world to join.
There are no costs, and the only requirements to join a fanlisting are your name and country. Fanlistings do not have to be large sites (although some are), they are just a place where you can sign up with other fans. TheFanlistings.org is the original (but not official) web directory for fanlistings, dedicated to uniting the fans.
Description from tfl.

natalia

Princess of the Kimuelasca Kingdom. She is sublime and proud, but at the same time she thinks of her people often and grieves for them. An archer, in times of trouble or danger she is a warrior with a strong will. She is also Luke's fiancee, and often scolds him for not accepting the responsibilities and positions of the nobility.
