Nerith is a square-faced sul'dam (TPoD, Ch. 22). She has black hair (TPoD, Ch. 23).
She soothingly braids her damane's hair in Bakuun's camp after saidar slipped away from her. Nerith thinks that, whatever it was, it is gone again (TPoD, Ch. 22).
After the first skirmish with the Seanchan, one of Bashere's patrols captures her and Rand says he wants to give her to the Aes Sedai. Anaiyella rather wants to see her dead. She is outraged when asked if she was a Seanchan Aes Sedai (TPoD, Ch. 23).
"Nerith had managed to sink her teeth into a Saldaean's wrist and was hanging on like a badger." (Rand on Nerith who is thrashing about while being bound; The Path of Daggers, Chapter 23)
