Nuadháin

Nuadháin is a figure from Irish mythology, specifically found within the Ulster Cycle. He is primarily known for his involvement in the tale of *Serglige Con Culainn* (The Sick-Bed of Cú Chulainn). In this narrative, Nuadháin is the father of the mysterious woman, Líban, who is transformed into a mermaid.

Nuadháin himself is often portrayed as a man of stature and influence, though the details of his lineage and personal life outside of his daughter's story are sparse. He resides in a coastal dwelling, which becomes significant due to Líban's transformation and subsequent entanglement with the hero Cú Chulainn.

The story of Nuadháin's daughter, Líban, is central to his appearance in the mythology. She is cursed by a sorceress and spends centuries as a mermaid before eventually regaining human form. Nuadháin's role is that of the grieving father who yearns for his lost child. His dwelling and his connection to Líban are crucial to the setting and initial premise of the tale, as Cú Chulainn is drawn into the supernatural events through his encounter with Líban. Nuadháin's character serves to ground the fantastical elements of the story in a familial context.
