Filvis Challia is a female elf who serves as one of the close aides to Ellenor Ljos Alf in the anime Wistoria: Wand and Sword. Her most distinctive physical feature is her long black hair and a mask she wears that covers her eyes. Apart from this mask, her appearance is nearly identical to her counterpart from the spin-off series Sword Oratoria.

Regarding her personality, Filvis does not subscribe to the strong sense of ethnic solidarity or the belief in elven superiority commonly held among her people. She finds these attitudes burdensome and has openly confessed to Wignall Lindor that she struggles to deal with the pressure of such expectations, especially given her own quiet and shy nature.

Her role in the story is primarily as a trusted subordinate to Ellenor Ljos Alf, placing her within the inner circle of a significant character in the anime's world. No information is available regarding her deeper motivations, detailed background history, key relationships with the main cast, any character development arc, or specific notable combat abilities.
