Shad was a cadre that arose from the Imperial family of Ashurad following the collapse of the Imperial period of Kiurandir. It went to war with a rival cadre, Asher, in what is now known as the War of Siblings. It survived this war, as is attested to by its inclusion in the Bailot Treaty. Following the Second Bailot War, Shad went extinct.
However many individuals in the Yield-Menien territories observe similar tradition to the Shad and their liturgical language preserves archaic features lost by Asher branch. Work between Yield-Menien and Asher is underway, reconstructing an accurate model of the Ashurad court dialect.
