The Original Earth.
It was one of the most notable planets in the Cosmos, and for a variety of reasons.
It was an Apex World, the smallest known Apex World, with a surface area of only around 500 million square kilometres and a diameter of roughly 12,000km.
Myths claimed the humans of this planet could achieve interstellar travel and reach different parts of the Cosmos without using any magic.
To them, magic, comprehensible universal laws, and similar phenomena existed only in their stories and fiction.
According to the accounts, they exchanged their advanced technological inventions for the magic and mystical arts used by the rest of the Cosmos, and through this exchange, they integrated magic into their technology, allowing their development to advance in leaps and bounds.
It was from this combination of science and magic that many of the widely used magi-technological devices, such as Arthur's phone, which he could charge with his magical power, were created.
