READ THIS TO GET A BETTER IDEA AND VIEW OF THE WORLD YOU ARE ABOUT TO ENTER
A universe was created by an angel who lost his way back to heaven and became a human reincarnate. The angel still possessed celestial powers, but they were too much for his human body to handle as he aged. Despite having siblings, he felt lonely and retained memories of his time as an angel. He finally made friends with a man, and they grew very close. The angel confided in his friend about being an angel. His friend went along with it, thinking it was cool, but the angel knew his human body did not have much time left.
He began distributing his powers by injecting people with his celestial blood. His friend was the first to receive powers because he had come up with the idea of distributing the powers. It worked, and the angel distributed the powers to his sister and many others. Later, he created a separate universe just above Earth where those who received powers could dwell and learn to harness their celestial aura.
In this new universe, he established a school for people who wanted to become stronger and protect their loved ones. He ruled the school. After some time, his friend asked for his own share of the school's leadership, but the angel refused. Infuriated, his friend left. The angel then embarked on a journey, leaving the school without a leader. His best friend took it upon himself to rule the school, changing many rules but unable to alter its appearance, as the school building was alive like the House of Mysteries and existed in another dimension within the created universe.
His friend ruled the school with an iron fist, executing those who opposed him. This caused a serious war between those who enjoyed his regime and those who didn't. There were numerous battles and deaths until the angel returned and stopped the war. He discovered that his sister and his friend had united and had a daughter. This news dismayed the angel. He banished both his friend, his sister who became his friend's wife, and their supporters into a different realm called Under Terra Firma, placing a strong seal on it to prevent them from breaking out.
Years passed, and as the angel prepared for another journey, he appointed 12 of the strongest people to oversee his universe and set rules for them. He placed his niece and her descendants in charge of the school. Then, the angel disappeared into thin air.
