Heart

Heart is a universe in the multiverse. It was created by The God and The Goddess in the image of Diem's home universe, Earth. Because it was based on Diem's perception of his own universe, Heart has no gods, no magic, and only a single plane, its world plane. The aspects constructed a world in the image of Earth's world, set into motion evolutionary processes based on Diem's understanding of his own world's science, and then left the plane to its own devices. Humans (but no other sapient races) eventually evolved on Heart and human history played out identically as it did on Earth up to the point of Diem's modern day. A piece of modern technology known as a Large Hadron Collider allowed its inhabitants to accidentally discover aether, the substance which universes and divine sparks are made of. With that discovery, Heart's technological advancement soon diverged wildly from Earth's as its inhabitants imbued their advanced technology with aether, creating divine supercomputers and ersatz magic items.
