Certhia

Certhia was seventh wife of King Mergus of Avornis and mother of Lanius.

Certhia had begun as Mergus' concubine. In the 30th year of Mergus' reign, she informed him that she was pregnant. As Mergus had no male children at this point, even after marrying six wives, Mergus was determined that, if Certhia's child was a boy, it would be legitimate.
