Arishem the Judge is the Prime Celestial, who is credited for creating the first Sun and bringing light to the universe. Millions of years ago, Arishem created the Deviants in order to aid in Celestial births, but when his creations went rogue, Arishem created the race of Eternals using the World Forge, in order to combat the Deviants, who were interfering in his work. One such world Arishem sent his Eternals to was Earth, in order to ensure the Emergence of Tiamut. Arishem communicated directly with Ajak on Earth, but after her death, he spoke with Sersi, informing her of the Eternals' true purpose in order to ensure the Emergence took place. However, the group grew attached to Earth and worked to successfully avert the Emergence, displeasing Arishem. Afterwards, Arishem pulled Sersi, Kingo, and Phastos into space in order to study their memories and judge if humanity was worth preserving.
