カルナッハ・ルーグナー Karunahha Rūgunā
Kallnach Rugner (カルナッハ・ルーグナー Karunahha Rūgunā) is a character mentioned in background supplements for Suikoden. He was Emperor of the Scarlet Moon Empire long before the events of the Gate Rune War.
Kallnach Rugner had two sons, Geil and Michelan. Although Geil was the eldest son and was expected to be named heir, Kallnach appointed Michelan as his heir. This decision would eventually lead to the War of Succession when Geil would try and wrest the throne away from Michelan's appointed heir, Barbarosa.
