Skasaher

“Hey, what're you gettin' all sentimental on me for?”
— Scáthach, to [Lana]()

Scáthach (Japanese: スカサハ Skasaher), known as Ulster in Awakening, is a prince of Isaach, the cousin of Crown Prince Shannan and one of the twin children of the presumed late Princess Ayra. Born during Ayra's travels with Sigurd of Chalphy, at age two he was escorted into hiding by [Oifey]() and his elder cousin Shannan, along with his twin sister Larcei and Sigurd's son Seliph. Seventeen years later, he was part of the beginning of Seliph's revolution against the tyranny of the Grannvale Empire.

In the gameplay of Genealogy of the Holy War, if Ayra died or was not married in the course of the first generation, Scáthach's role is filled by [Dalvin](), his substitute.
