She appears primarily in the Irish tale of Serglige Con Culainn (The Wasting Sickness of Cú Chulainn), where she is the daughter of Áed Abrat. She appears first in the form of a sea bird, then as an otherworldly woman who inflicts the story's eponymous sickness on Cú Chulainn. In the story Lí Ban acts as messenger and mediator; she and Cú Chulainn's charioteer Láeg work together to see that Cú Chulainn is healed in exchange for his aid in Fand's battle in the Otherworld.
