Lenneth has actually two sister.
She is Lenneth's youngest sister. This Valkyrie is more detailled in VP2. In Lenneth's Story, Silmeria is kept inside Brahms Castle, due to the battle they had with Freya in the past.
Lenneth's big sister, she is known too as the Dark Valkyrie. She appears as evil in VP1, not hesiatating to take Lenneth's body, trying to kill her Einherjar and showing no remorse to the fact she nearly destroyed Lenneth's soul.
She is defeated by the unlikely alliance of Arngrim and Mystina, with Lezard and Brahms, allowing to Lenneth to reborn... And to put her power more high than never. In VP2, though, Hrist shows herself as better near the end.
