Sebila of Disart (pronounced SEB-ihl-lah of DIE-sahrt) was a Tortallan noblewoman of the 5th century HE, but was likely born in the 4th century. She is likely a Goldenlake by birth and a Disart by marriage.
She was Lord Raoul's great-aunt. He referred to her as a dragon. She was hard of hearing and wanted Roaul to get married. This only increased his dislike for Lady Sebila, because Raoul liked to determine his life himself, without the interference of his great-aunt.
Her relation to Balduin of Disart is unknown.
