World Description:
This world is still referred to as Earth, however, it's around 10x the size of the Earth that we know. Although this should effect the day/night cycle, for some reason, it doesn't (plot twist, hint hint). The world is infested with large bug-like creatures called "The Unseen", they're called that due to their speed, agility, and general ghost-like existence. They aren't ever seen when they kill, the only people who can kill them are called Transcendents. People who's power has eclipsed that of the Unseen. Unfortunately, the most powerful Transendent disappeared 15 years back, and since then humanity has been fighting a losing battle.
Transcendents:
Transcendents are people who can do the impossible, superhumans beyond the word superhuman. They are typically righteous individuals, people who fight for the sake of humanity at the center of cities, however, there are those who seek to end humanity, and give in to the Unseen. There are only about 50 million people left on the planet, spread across all the continents in large cities with about 7 million people per city, and one city per continent. These cities are connected with wormhole devices that allow rapid transportation between cities. There is one final city that connects to them all called "The Academy". This city's sole purpose of existence is to train new Transcendents how to fight the Unseen.
