Sasheoka was the Grandmaster of the Scarlet Spires, assassinated in 4100 by the Cishaurim and succeeded by Hanamanu Eleäzaras. Sasheoka was assassinated by the Cishaurim because they incorrectly believed the Scarlet Spires to be responsible for the creation of skin-spies, which Anasûrimbor Moënghus discovered in Shimeh.
