Izzi and Gibran met when the group fled from Nur. Izzi died before she could tell Cook how the latter meant to her. The Commandant learned about their friendship and manipulated it to her means, punishing Izzi instead when Cook offended her. When Izzi arrived at Blackcliff, Cook took care of her. Izzi and Cook have a special relationship. Izzi and Laia reunite and they remain close friends until Izzi is killed. When Laia had to choose between going with Keenan or saving Elias, she gave her space on the boat that was going to take her to Keenan to Izzi. The two began working together to help the Resistance. Izzi insisted on helping Laia even though she knew how dangerous it was. Laia and Izzi became friends after Laia needed Izzi's help to get out of Blackcliff for her meeting with the Resistance. Elias helps her spirit cross over into the afterlife. However, when the caravan is searched for Scholars, Izzi is found and killed. When she is in the caravan traveling to Kauf, Gibran Ara-Nur develops a crush on her. While the four of them are traveling to Nur, a sandstorm hits, injuring Izzi's remaining eye. Izzi notices Elias is unwell, but Laia denies it because she had promised Elias to keep his condition a secret. They eventually catch up to them and tell them that they are going to help them break into Kauf Prison to save Darin. Izzi and Keenan have been tailing Elias and Laia.

Laia sends Izzi to escape from slavery with Keenan in her place. They find one but are caught by Marcus and Zak Farrar. Later on, she helps Laia search for a secret entrance to Blackcilff for the Resistance. At the Festival there is a raid, from which she escapes with Laia and Elias Veturius by going through the catacombs. After Izzi decides to help Laia, giving what information she knows, the two of them sneak out of Blackcliff to go to the Moon Festival in Serra. Izzi befriends Laia against Cook's wishes and soon figures out that Laia is a spy for the Resistance. Her missing eye is the result of Cook's attempt to poison the Commandant, who took Izzi's eye rather than punishing Cook. Izzi was five years old when she arrived at Blackcliff Academy with Cook.
