The Nexarion Realm, a reality coexisting with Earth, separated by a dimensional barrier.
This world remains shrouded in mystery. On earth, it's existence is unknown. It's inhabitants can't comprehend it either, nor can science can explain it.
Many centuries ago, a devastating war among the 25 nations took place, threatening to wipe mass civilization. As a result, a powerful group known as the 5Gs, placed barriers above each nation, isolating them for safety.
Soon multiple dimensional cracks, dubbed as Nexarion Gates, formed around each nation, causing earth to be used as a neutral ground for diplomacy and exploration.
Noticing similarities in appearances, environments and more, nations decided to adopt Earthly customs in preparation of potential integration.
In the present, many Nexarions have incorporated Earthly customs into religion, society politics, economy and more.
Many may agree with change, many may not.
