History
Norrin was a Zenn-Lavian who became the Herald of Galactus. After Galactus' defeat when Doctor Doom swapped minds with him, Norrin decided to have a quiet life as a farmer, having married Emma Frost sometime later.[1] Because Doom had devoured everything in the Universe, including the Sun, Norrin gave his Power Cosmic to Jonathan Storm, and this way he was able to become Earth's artificial Sun.
When Doom returned to Earth, Emma used a machine built by Reed Richards and the visiting Victor von Doom from the Prime Marvel Universe to swap minds with the world devourer. Before she transferred her mind, Reed planted an overriding instruction in her mind to rewrite Galactus' nature, turning Emma into a force of universal restoration instead of destruction, a Lifebringer that started navigating and rebuilding the universe. Additionally, Johnny Storm decided to give Norrin back the Power Cosmic, so he could accompany his wife throughout the cosmos.[2]
