Iselle Arrel was the young daughter of Edeyn Arrel.
She was tall and full mouthed with long black hair that fell below her hips.
She claimed she could channel the One Power, for she had been tested by an Aes Sedai. She also stated that the Aes Sedai said she had a strong potential. This strikes as untruth; had she truly been tested, she would likely have been dragged off to the Tower the very same day.
Edeyn planned to have her marry Lan Mandragoran so Iselle could one day be Queen of Malkier. Iselle didn't want this for herself as she knew her mother was already Lan's carniera; instead she wanted to go to the White Tower with Moiraine Damodred and Siuan Sanche. After she watched Merean Redhill kill Brys and Diryk, she was killed by Merean.
