Irina was a female Human on Cestus III, born in the 2320s. As a child, she was best friends with Esperanza Piñiero. When Piñiero was nine years old, the two had a fight, and all of the rest of their mutual friends sided with Irina against Esperanza. Piñiero recalled this event (and the advice family friend Nanietta Bacco gave her afterward) as an adult in 2380, prior to the ceremony making the world of Koa a Federation member state.
