A country ruled by Lord Laniure in Heinrich von dem Türlin’s Diu Crône. When he died without a male heir, his daughters Amurfina and Sgoidamur vied for control of a magic bridle which gave its owner the rights to the land. Gawain eventually decided the feud in Sgoidamur’s favor, though he married Amurfina. Another King of Serre appears in Girart d’Amien’s Escanor at the tournament of Banborc.
