Igrene has an estranged husband, who was a thief named Gorlois, now a spy in service to House Ostia. It is revealed in a support conversation with Fae that Igrene had a daughter who has since died from unknown causes. When prodded by Fae to reveal more information, it is suggested that she is still deeply pained about her daughter's death, but seems to be holding back her emotions. In her support conversations with Saul, it is mentioned that Igrene used to believe in a god, but lost her faith after the death of a loved one.
In her first appearance, she is evading Bern's forces to avoid capture and protecting Fae until Roy arrives. After the war, she disappears back in her home, Nabata, just like Sophia and Fae.
