E'soon G'nipparw was a middle-level demon who worked for the Southern Horde in the Duchy of Southern Yamato. He preferred to stay in his demonic form most of the time, and he was willing to sacrifice his minions to lure his enemies into a trap. He was ambitious and arrogant and wished to rise in the hierarchy of his horde by capturing the Black Hunters who had eliminated many of his kin. He also knew powerful spells and could conjure a fog to a large area. E'soon met his end at the hands of Seria Greaplane while trying to capture Zeranafska from the Black Hunters.
