The year is 2025 NCE or New Common Era. The Earth has only just barely managed to return to the level of technological advancement they achieved before the Apocalypse Wars. And now the survivors of that war have gathered together on one large supercontinent known as Terra. Many of the landmasses and of the past have been sunk with almost all of the technology and history along with it. Miniscule amounts of information can be sparse together for the people to use and rebuild, but at most they have returned to what modern day looks like. There are Seven Empires and hundreds of smaller nations of all sorts spread throughout the land. It is here that our story takes place.
For the past decade the world has been slowly merging with another in what seems to be another apocalyptic event. But surprisingly enough there are no backlashes to be seen for the people of both worlds. Instead in their eyes it just seems like a new continent just mysteriously appeared on the other side of the world. From a parallel Earth, this supercontinent was named Gaia. For the last decade everything was fine, and the people managed to make contact with the other continent and they even established trade and travel to their respective lands.

But all of this changes with the descent of The Final God. They explain that They will be granting power to the two merging worlds. A power that was needed seeing as these two worlds were about to fall victim to the powers of the multiverse. These came in the form of Dungeons and Gates. The Dungeons and Gates connect this world to others in the multiverse.
And so The Final God grants His three blessings to this world. The access to mana that these other worlds already use in their everyday life. The system that will help the denizens of the world adapt quickly to the new world order. And most importantly the ability to Awaken.
The Awakened will use the mana that is flooding the world in order to combat the forces they are up against. Meanwhile the mana given by TFG(The Final God) will begin to reshape the world in a manner befitting the dangers they face. It will create resources for the denizens to use in order to equip themselves with the abilities and knowledge needed to continue their fight for survival.
And this is the bare minimum lore needed in order to read the story.(Probably won't be able to explain it as concisely in the story.)
