Lilin Von Rubistein is the sister of Neinheart. Her brother left to find Ereve a new Empress whereas Lilin stayed to wait for the Heroes to return. She would come into contact with Aran and would help her in recovering her memories and prowess.
She appears in Heroes of Maple, after being captured by Damien's demon army. She was eventually rescued by Evan, Aran and Shade and returned to Rien. She goes to the Temple of Abraxas within Nihal Desert, talking to Neinheart after Damien's defeat. She also makes an appearance in FriendStory where she asks the player is they knew where Neinheart was. She then threatens the player to not tell Neinheart. The player does, however, and Neinheart remorses how she hasn't called him brother in a very long time, hinting at some kind of aggression.
