After learning that their true mission on Earth was to prepare it for the Emergence of the Celestial Tiamut which would destroy the planet, the Eternal of Earth sought to stop by having Druig put the Celestial back to sleep. When Druig explained that his power alone was not enough, Phastos conceived of an idea to have the Eternals form a joint Uni-Mind and empower. However, when Ikaris was revealed to be loyal to Arishem and the cause of awakening Tiamut, Sprite chose to follow him, while Kingo believed in the same cause but refused to fight the others and left.
The remaining five Eternals tried to form the Uni-Mind, but this attempt was violently stopped by Ikaris, who punched Druig into a mountain and proclaimed him dead. Sersi attempted to stop the Tiamut herself, and when Sprite sought to stop her, Druig showed himself to be alive and came to Sersi's help, knocking Sprite out. The Eternals eventually formed the Uni-Mind which empowered Sersi and enabled her to to turn Tiamut to stone before he could fully awake. With what was left of the Uni-Mind's power, Sersi granted Sprite's wish and turned her into a Human, allowing Sprite to finally grow up and age.
