Melanie Sutherland (née Hayden) was the daughter of Lord Sylvester Hayden and his wife Beatrice. After her mother was widowed, she remarried to Lord Gavin Zosimus. Thus Melanie grew up with her adopted brother Vincent, her stepsister Laura, and her half-brother Balian.
She survived the destruction of Isidore and was taken prisoner by King Aldous along with Laura. After Laura married Aldous, she installed Melanie as her lady-in-waiting to keep them together. This arrangement proved disastrous, as Melanie was subjected to the abuse of Aldous and his men.
To escape the mistreatment, Melanie married Malcolm Sutherland. It is unknown whether the couple had any children.
