Sersi quotes from Eternals (2021)

Sersi

We were instructed not to interfere in any human conflicts unless Deviants were involved.

I love you, Sersi.

Sersi

I love you too, Ikaris.

Sersi

Something unusual is happening to Earth.

It is a side effect of the Emergence.

Sersi

The Emergence?

It is time for you to learn the true purpose of your mission. You were sent to Earth to help the birth of the Celestial Tiamut. Every billion years new celestials must be born. I plan celestial seeds into host planets across the universe. 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

Sersi

But everyone on Earth will die.

The end of a one, Sersi, is the beginning of another. Our universe is a constant exchange of energy. An infinite cycle of creation and destruction. Celestials use energy gathered from host planet to create suns. Generating gravity, heat and light, for new galaxies to form. Without us, our universe will fall into darkness. All life will die.

Sersi

Everything dies except us because we were never alive. Why don't I remember any of this?

Because your memories are erased and reset after each emergence. They are stored here.

Sersi

Why do you keep them?

I keep them in order to study the deviants. I created the deviants, Sersi, for the same purpose I created you. Every Celestial host planet has its own predators. I first sent the deviants to exterminate them so intelligent life can grow, but there was a flaw in the design. They evolved, became predators themselves and I lost control of them. I built and programmed you Eternals to be synthetic beings and incapable of evolution, to correct my mistake.

Phastos

When Arishem made us, he embued us with infinite cosmic energy to keep our bodies regenerating. The bracelets in theory shut down our regeneration process. Once that happens, our bodies accumulate extra cosmic energy.

Sersi

What for?

Phastos

Well, the deviants can absorb our energy. What if, we can absorb each other's energy as well? If I can find a way to connect us all, one of us could become immensely powerful pulling the accumulated energy from the rest forming.... a Unimind. Uni meaning one, mind meaning mind.

Oh no, we heard you the first time.

Sprite

Terrible name.

Brainstorm... Brainstorm, that's a way better name!

Phastos

No, I invented it so I am calling it whatever I want!
