There has to be a first, and among Immortals that honour is accorded to the Shemsu-Heru, the friends or companions of Horus. Created by Isis and her sister, originally to follow and serve her son Horus, they are the oldest Undying in the world. The original Immortals of Khem, the land of black sand and pyramids. Bound together by their shared culture and the tenets of the Wat Hor they continue to work towards Horus's twin goals: vengeance against Set and the defeat of Apophis. In the Final Nights, they are known as the Imkhu.
