Willa

"Willa was the only one of the prisoners Einsa had ever met that was kind to her. She was the only one Einsa had ever wanted to be close to, to learn about, to understand, and to care for." "—The Sword and Its Servant"

Youngest of the escaped prisoners that made their escape alongside Einsa. She was the younger sister of Tobias.

Biography
Willa was brought to the Kaltstein along wit her brother, Tobias, while their parents were away from home. The pair took refude in a storm cellar, but did not find their basement on the other side.

She was the only prisoner that was ever kind to Einsa, and as a consequence became Einsa's one and only friend. The two were very close to one another.

After making their escape together, Willa and Eisna were separated in the swamps beyond the Kaltstein's outer defensive wall. Einsa found some of Willa's tracks, along with one of her pursuers and followed them out of the swamps and into the fields in lands beyond the Kaltmark.

Personality and traits
Willa was very reserved and frightened, which was typical of a young girl of her age and size. She clung always to Einsa and at times, to her infirm brother, Tobias.
