As described in First Channel, Willa had dark blond hair and wide blue-green eyes in an otherwise plain face. She seemed sturdy, the kind of person you'd find on a pioneer homestead. Rimon and Kadi gave her the name Willa.
With Kadi's guidance Willa became self aware and was able to give Rimon transfer without harm to herself.
She gave Jord Veritt transfer and later fell in love with him and they married.
In Channel's Destiny Willa's death is mentioned but not how she died.
