The sister of Percivale, she went on the Grail Quest with her brother. The questers came to a castle where it was the custom to demand the blood of passing women to cure the leprous mistress. Hearing of this, Dindrane voluntarily donated her blood and died in so doing.
Dindrane is sometimes associated with her own shield. The design of her shield can vary, but it often incorporates symbols or imagery representing her virtues, such as purity, faith, or spirituality.
In Italian romance, Percivale’s sister is called Agrestizia.
