3500 AD, Sector 1, Silver Lake City, Planet Terra :
A huge tower can be seen in the skies. There are people at its closed entrance who are very excited to enter the tower. This is the Tower of Apocalypse, it's a doomsday sent by Gods that ultimately even swallowed gods themselves.
The gods are trapped in this tower now. Worse this tower supressed their powers and authorities. 400 years ago this tower appeared, this tower gave the opportunity for humanity to become gods. They can climb the tower and earn glory, power, riches beyond their imagination.
But even among the humanity only three managed to become gods until now and transcended the boundary of life. The three gods are the pillars of humanity that protected the planet of Terra from outside enemies that tried to enslave their race.
About 40 years ago, an army enough to eclipse all the light around the world descended on the planet Terra. Even awakeners are no match for their power as they harnessed the bloodline of old gods and demons. There are many type of races among them.
Humanity's only hope are the three gods. They take the fleet head on and sent the troops of enemy back in a matter of minutes. Since then humanity understood they in future needs to grow in power as their enemy is also improving.
Three gods are enough for now, but in future what if they have gods too, it'll be a difficult situation by then. That's why the three gods of humanity are doing everything they can to nurture the generations of awakeners. There is always a myth that every hundred years a person with the potential to become a god will born.
The three gods have the talent above ss rank. S rank skills are very rare not to mention ss rank that may not appear in decades. sss rank skills are simply unheard. the three gods have the skills - Dragon King's Heart, Beast Monarch of war, and Empress of ice.
This skills in their journey evolved into their divinity and paved way for them to transcend the limitations. They're still waiting for the fourth person to get the skill at their level. This year's awakeners who has innate mana inside them are at the Tower now to get their awakening.
Among them a particular boy stood out. He is none other than Allen Knight. He is a reincarnated person in this universe. Allen is waiting for the awakening too. When he gets into this world he is all alone. Growing up in an orphanage he didn't get much care and love that normal kids did.
Allen is also excited for this life. As for traveller cheat or something. He already tried it and didn't get any. He didn't get discouraged though. As long as he has a stable life it's enough for him. If he gets enough power he will try to climb this tower, if not he will be on lower floors becoming an employee of any good guild here.
Allen is now at the entrance of tower like all teens his age with mana. He is 15 this year and considered ready for awakening. Every one who reached the age 15 will be an adult in this world and if they have mana they can awaken or they can also become an ordinary person and live their life.
Allen looked at the tower stretching to the skies with an amazed look. Even though he saw the tower many times it's still is amazing to see the tower that stretched to the skies. As Allen is thinking the tower lit up lightly and the entrance opened.
Their instructors guided them into the tower. Military is maintaining the situation so no one will be affected by the crowd. Every awakener is precious to the military, of course unless you're an extremely low rank or a sun who chose the evil path.
As they're guided into the tower they saw a temple in front of them. In front of the temple is an angel. Yes, an angel who is guiding them inside. The tower will give an awakening skill in the temple of cosmos. Angels once served the gods now they're agents of the tower, of course not all of them though.
Some angels chose to live in seculsion abandoning gods and tower alike. Some still serves the gods while few joined with demons and become fallen angels. If you come across a fallen angel, fight if you the power and courage or run away as fast as you can or kill yourself before getting caught is the saying.
Because fallen angels of gregori are known for their cruelty in torturing the awakeners and humans alike.
