David gazed up at the sky, his eyes drawn to the three moons of Steel that hung low in the morning sky. The planet they called home, Nougat, was a world colonized by humans who had fled Earth centuries ago.
As he stood there, David's mind wandered back to the history of humanity's expansion into the universe. It had been a turning point in human history when they decided to explore the cosmos, seeking new resources and opportunities. However, they soon discovered that they were not alone in the universe.
The Star Beast, creatures that utilized the power of stars and the universe itself, had been a formidable foe. Ancient humans had soon realized that their weapons were useless against them, and they were helpless against the Star Beast's attacks. It wasn't until 60 years later, with great sacrifices, that humans discovered the technology of the ancient Satochi race.
Using this technology, humans created Mechs, powerful machines that could harness the power of runes to fight against the Star Beast. While Mechs enabled humans to fight back, they were not enough to save Earth from destruction. The planet was invaded by a powerful Star Beast, and humans were forced to colonize other planets.
This marked the beginning of the Age of Mech, a time when humans relied on these powerful machines to fight against the Star Beast. Mechs were powered by runes, which absorbed star energy and produced power similar to that of the Star Beast.
David's thoughts were interrupted by the sound of his wrist comm beeping, signaling an incoming message. He looked down and saw a news report about a recent Star Beast attack on a human colony.
The Star Beast were classified into five categories, ranging from Level 1 Spark Beasts to Level 5 Stella Beasts. Each category had its own unique characteristics and abilities, and they were further classified into low-grade, middle-grade, and high-grade.
Humans had never seen a Star Beast higher than Level 3, which was a high-grade Flame Beast that had destroyed Earth. The thought sent a shiver down David's spine as he wondered what the future held for humanity.
