Arishem the Judge

"You have chosen to sacrifice a Celestial for the people of this planet. I will spare them, but your memories will show me if they are worthy to live. And I will return for judgment."

- Arishem to Sersi, Kingo and Phastos

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, the Judge 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 instead made contact with Sersi, informing her of the Eternals' true purpose and to ensure the emergence takes 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.

Revealing the Eternals' Purpose
"The planet Earth was chosen to host the Celestial Tiamut, In order to grow, Tiamut needs vast amounts of energy from intelligent life forms. The Deviants prevented this by consuming humans, until the Eternals eliminated them. Now, the human population of this planet has reached the required amount. It is time for the Emergence to begin."

Abducting the Eternals
Later, after learning about Tiamut's death, Arishem personally came to Earth, his mere presence causing massive weather changes to the planet. He then summoned Sersi, Kingo, and Phastos, with whom he expressed his displeasure with their having sacrificed a Celestial to save the human race. However, Arishem agreed to spare them, but only if the Eternals' memories demonstrated that they were worthy. He then left with them through a singularity.

Personality
"The end of one era, is the beginning of another."

- Arishem

Arishem is entirely dedicated to the role of the Celestials in the universe, and as a result, holds both little regard for lesser life by using them as a sacrifice, but also high regard as they willingly create innumerable worlds with sentient life in them. Arishem understands that life and death is a cycle, and the destructions of inhabited planets is necessary. Arishem is distant and shows objective understandings and no biased/prejudiced decisions, as he does not appear angry when Tiamut is stopped by the Eternals.
