Nicola Treehill is a former weaver from Ghealdan, who was engaged to a man named Hyran. She becomes a novice of the Salidar Aes Sedai. Her potential is almost as much as Egwene al'Vere's and she has two Talents - Foretelling and seeing ta'veren. Nicola is around the same age and height as Nynaeve. She is slender, dark haired with big black eyes.
Nicola is introduced when Nynaeve and Elayne are aboard the Riverserpent headed for Salidar and along with Areina decides to accompany them. Upon reaching the Salidar Aes Sedai camp Nicola's potential is realized and she is quickly thrust into Novice white. Throughout the remainder of the novels, Nicola is a source of irritation for many of the Aes Sedai. She tries to blackmail Egwene, Nynaeve and Elayne as well as Nisao Dachen (of the Yellow Ajah) and Myrelle Berengari (of the Green Ajah), who have been keeping Lan concealed. It is during an attack due to a bubble of evil that Nicola has a Foretelling and when Mat shows up, she is brought over to him claiming to see him surround by light, thus revealing her Talent for seeing ta'veren. Eventually Nicola, along with Areina, runs away and, we learn, heads for the White Tower. When Egwene is captured, Nicola apologizes to her for leaving and informs the novices there of Egwene's deeds and leadership as Amyrlin.
Nicola is killed in Tel'aran'rhiod in the book Towers of Midnight.
