he fan teaser promises an exciting continuation of the Eternals' saga as they defend the Earth from the Celestials and other intergalactic threats using images from Eternals as well as a number of previous MCU movies. 

The team's victory over the Deviants, who had been their longtime adversaries, marked the conclusion of Eternals. 

The Eternals discover that the Celestials actually used Earth as an egg to create a new member of their species, and that they were just responsible for maintaining the planet to guarantee this happened.

After they succeed, the Celestial Arishem chooses a number of Eternals and takes them away from Earth so that they may be held accountable for their deeds.
