The Unsung Heroes/Terminology - World & Realms

Terminologies:
For the sake of understanding the story's elements, contents, and etc. I have devised a lists of terminiologies to follow along the storyline for easing your pain to understand it. If you want to know where I got the inspiration or motivation, then you're more than welcome to guess.

The Original 13 Sacred Gears:
This class of Sacred Gears is specifically named after the first 13 Original Longinus made by the God from the Bible. In the Great Cataclysm War, the pre-war generation of possessors of 13 Original Longinus died to protect their world, passing their respective Longinus to the next generation.

Unlike the other Longinus, this class of Sacred Gears are extremely rare to possess, where a possess appears every once decades to centuries due to their immense powers, some speculated that an unknown phenomena caused the Original 13 to be in a state of deep slumbers, or healing from the aftermath of the Great War.

The Post-War Longinus Gears: (still working on a name)
This class of Sacred Gears consist from Sacred Gears that have evolved after the Great Cataclysm War and of unknown origin. So far, there has been total of 12 Post-War Longinus Gears in the last three millennia after the Great Cataclysm War.

The following Post-War Longinus Gears are  Some speculated that it was caused where powers of the Original 13 Sacred Gears were split off partially, causing the splitting energies to nurture, developed, or combined with other powers to create new Longinus. Hiroaki speculated that due to the Great Cataclysm War, the the Holy and Demonic Powers were left in the aftermath of the battlefield, causing the Sacred Gears to face  irregular phenomenons and evolved into Longinus.

Drakon Etoulde (World of DxE):
It is the current world where Hiroaki Saeba lives. This world was said to have been created by the survivors of the Great War where the two world of DxD and ExE combined their powers to recreate the desolate world and combined into one single dimension for them to live on. In terms of the landmasses and seas, it is similar but different variation of the world of DxD where there are mainly two continents divided into east and the west. Along with the continent, there are many species living in their respective lands and territories, there are also kingdoms and empires that are governed by either human or demi-human beings. As beyond that point, the world is governed by higher beings such as Gods, who are divided into various rankings. It is speculated that there is a supreme god who have said to laid the foundation of the world, but no one knows to this day.

After the world was combined, the two supreme gods from ExE, Benevolent God Resetoras and Malevolent God Melvazoa have laid to deep slumber, allowing their subordinates to act on their behalf until their eventual return to the world.
