Arcanthys is a world where 5 main bipedal races live. They are Daemons, Elves, Dragonkins, Druids and Aegis. Being only in 745 AD(After Dragons), most would expect their world to still be in a medieval era of sorts.
But in 700 AD, General Volvovich of Icelis surprised the world by managing to topple the centuries old Ivlit Dynasty which had been ruling the nation since it's birth.
He claimed to be a genius but most knew something else was in play. After the 8th coalition, it turned out, they were right. He has been extracting technology from another world called Urth or the mystical lands of Terra.
Most agreed to not try anything with this world anymore as they think the tech that they have was already enough. In comes 4 different factions. The Cult of Ulaal, the newly born Icelisian Commonwealth, Empire of Shinosei and New Wallachia.
All four factions, simultaneously tried to access earth in secret, each with their own objective with New Wallachia's being to confirm the origin of the Vlad Dynasty.
When the attempts failed, multiple cities from Earth were transported to Arcanthys and their denizens too were mutated after exposure to mana.
After the cities were restored, the UN's new Security council(new one since ww3 happened due to Volvovich's peeking causing radiation to be replaced by mana and nukes not exactly working) and league of 5 Hyferions decided to host an exchange where both worlds would exchange their knowledge. Earth was surprised by Arcanthys seemingly surprassing their technology. This would mark the beggining of a sort of merge over the years as earth was constantly exposed to mana and Arcanthys, to science and technology
