How do you merge the worlds of Bladedance of Elementalers, Magika Swordsman and Summoner and RWBY into one coherent, unified world with shared lore, history and backstory, with the lore of each series intertwining with each other, starting with the rise of the various deities, nature spirits and folk lore entities that exclusively form a contract with preteen and teenage girls along with young to early middle age women between the ages of 13-35, with the pregnancy of the contractee terminating the contract between the respective human or supernatural creature female and their respective spirit known as elemental spirits from Bladedance of Elementalers, which are the same entities as the manifestations of a creature, a concept, or a character from some mythology or folk belief, inhabiting Astrum from Magika Swordsman and Summoner, an alternate dimension [Astrum] parallel to Earth known as the Divas, who [the Divas] normally form contracts with young girls from the age of 14, with the young girls and women who form a contract with the Diva having a mark known as a Stigma from Magika Swordsman and Summoner and [the Divas] having the ability to allow their contractors to summon the magic armor that can only be used by Diva contractors, normally taking the form of skimpy mage and Knight armor akin to those seen in eroges, perverted J-RPGs and perverted Japanese fantasy games, Décolleté Oblique [Cleavage required] from Magika Swordsman and Summoner in this scenario,  after a devastating nuclear apocalypse following or happening during an unspecified Third World War between a US-JP-ROC-PRC-EU coalition and a Neo Soviet-Iran-Isreali coalition which subsequently ended the industrial civilization developed by the Industrial Revolution and refined by the development of computing into a digital civilization and mankind’s reversal to feudalism and then absolutist monarchism, albiet with some heavy industrialization after the war, although the Divas had already re-emerged before the Third World War, but being hidden from the world and/or concealed as psychic powers, with Diva contractees having been passed off as psychics, with specialized academies being set up to train Diva users in their powers,how the Ordesian Empire from Bladedance of Elementalers came about from both Neo-British Empire revivalists in Canada and Romanov restorationists in the ruins of Russia who then joined forces against warlords from Siberia, Europe and the former USA, what happened to Europe from the Azores to the Ukraine-Baltics-Belarus-Poland European Russian border, taking in mind that the entire Italian peninsula, Libya and all of the Horn of Africa seem to be under the rule of the Holy Kingdom of Lugia from Bladedance of Elementalers, a neo-Kingdom of Italy that seems to be under the rule of the Italian Bourbons instead of the Savoys but is in reality controlled by the Roman Catholic Church, Scandinavia [including Iceland] seems to be populated by mostly dragons and has united into the Empire of Dracunia from Bladedance of Elementalers, but what was once Germany, the former Prussian territory in Western Poland, a small part of Lithuania, the Russian Kalingrad region, Belgium, the French region of Nord-Pas-de-Calais, Luxembourg, Alsace–Lorraine and Czechia has broken away from Lugia’s control as a single state, more specifically a restored/reconstructed/revived Holy Roman Empire ruled by the Hapsburgs as its reigning imperial family whose government is a mixture between that of the German Confederation and Nazi Germany’s, known as the Principality of Rossvale from Bladedance of Elementalers, Syria seems to have overthrown the Assads and united with Jordan and Palestine to conquer Isreal and form a Levantine Federation, known as the Alphas Theocracy from Bladedance of Elementalers, the Quina Empire from Bladedance of Elementalers, located in the China region, more specifically ruling over the fifteen provinces of Han, excluding Yunnan, which would break away to form a restored post-937 AD, pre-1243 Song dynasty-tributary state of the Bai-Han Chinese Imperial House of Duan-ruled dynastic royal imperial monarchy Dali Kingdom and Guangdong and Guangxi, which [Guangdong and Guangxi] would [Guangdong and Guangxi] come under the rule of a restored Cantonese nationalist, Cantonese supremacist, Cantonese expansionist main branch of the Han nationalist, Han supremacist, Han imperialist Chinese nationalist, adhering to Dr Sun Yat Sen’s three principles of the people: nationalism, democracy and Socialism Revolutionary group/political organization of the Kuomingtang [Chinese Nationalist Party]-ruled, adhering to the political principle of Dǎngguó [Party-state], which [Dǎngguó] was [Dǎngguó] modeled off the Soviet Union’s system of dictatorship and [Dǎngguó] meant that major national policies of the state’s government bureaucracy were formulated by the Kuomintang, giving the party [the Kuomingtang] supreme power over the whole nation,which meant that bureaucracy had then become the means and the tools of Kuomintang, where all the major national policies were formulated, while resulted in the party holding the supreme power of the whole nation with military personnel and civil servants alike were expected to owe their allegiance to Kuomintang first and the state second, a policy reflected by such phrases as “Service to the Party and the Nation” (功在黨國) and in the national anthem, which makes an explicit reference to “Our Party”, unitary, adhering to Dr Sun Yat-sen’s three principles of the people: nationalism, democracy and Socialism one-party directorial Republic under a totalitarian military dictatorship of the National Government of the Republic of China/Nationalist China/Second Republic of China based [Nationalist China] in Guangdong and Guangxi, although a reconstituted post-1912, pre-1924, Cantonese independence, Cantonese nationalist, anti-Chinese unification, anti-Sun Yat-sen and thus anti-Chiang Kai-shek Nationalist Chinese government faction/Chinese warlord clique/Chinese military junta of the Old Guangxi Clique would hold most of the power in this restored Nationalist China ruling over Guangdong and Guangxi once more, [the Quina Empire in the China region] is just simply a restored stratocratic [military governed/military dominated], democratically elected bicameral legislative branch divided into a Senate and a House of Representatives known as the National Assembly founded 8 April 1913 which elected the president and vice president for five-year terms, and appointed a premier to choose and lead the cabinet, whose senators were chosen by the provincial assemblies and representatives being chosen by an electoral college picked by a limited public franchise, whose task was to write a permanent constitution, draft legislation, approve the budget and treaties, ratify the cabinet, and impeach corrupt officials having, Beiyang

and lead by former Qing Army general turned the Beiyang Government’s first President, Yuan Shikai as the Hongxian Emperor from 1915-1916, [the Quina Empire in fact being a restored Beiyang Government, more specifically a restored Empire of China] but [the restored Empire of China] lead by the descendants of the Ming dynasty’s reigning imperial family, the crypto-Sunni Muslim Han Chinese Imperial House of Zhu, [the restored Empire of China being lead by the Zhu descendants] as its reigning imperial family instead of Yuan Shikai’s descendants, due to the immense Ming restorationist sentiment in China proper ever since the conquest of the Ming by the Qing from 1644-1662, which lead to the rise of the Taiping Heavenly Kingdom, the Xinhai Revolution, the Northern Expedition and even the CCP victory as all of these regimes were expected to restore the Ming as the government of a post-Qing China, but obviously didn’t, but with no USA or Russia to stop this, Ming would be restored after the nuclear apocalypse and emergence of elemental spirits, but would only rule over the core of Han China and would have to implement reforms from the Northern Expedition to Chinese Civil War Nationalist rule over the China region and the post-Chinese Civil War CCP rule over the China region to survive, with the simultaneous emergence of the creatures of Grimm [human and supernatural eating

After the nuclear war, the rise of the Grimm, Tableau D’éclat Lumineux and Semblant and the emergence of Dust, Japan remains politically, economically and military stable and [Japan] remains a parliamentary imperial royal democratic monarchy under the rule of the main branch of the reigning Japanese imperial family, the supposedly Shinto-pantheon-descended, Japanese Imperial House of Great Yamato with the respective clan heads of the Imperial House of Great Yamato reigning over Japan as Emperors and Empresses of Japan as Japan's constitutional reigning theocratic dynastic royal imperial combined heads of state and once more of the Japanese armed forces respectively, even after these changes and thus [Japan] is able to reclaim Taiwan and the Pengu Islands, the entire Korean peninsula, Russia's Sahlakin and Kuril Islands as provinces, but [Japan] also experiences a mass migration of Faunus fleeing the four Kingdoms, changing its [Japan's] demographics, [Japan] becoming Menagerie from RWBY.

Schools to train the Chasseurs known as Huntsmen Academies from RWBY pop up all over Renmant after the formation of the Kingdoms.

The development of communication technology in Remnant which allows instantaneous multimedia communication wirelessly over large distances, mostly on four primary relay towers located in each of the four Kingdoms respectively with first and largest of these towers being located in Atlas, with any one of them being taken offline for maintenance – or fail for other reasons – causing the entire system to collapse known as the Cross Continental Transmit System from RWBY, [the CCTS] is developed in Atlas from Soviet and American military technology and [the CCTS] then refined by Menagerie and Mistral scientists before [the CCTS] going global.
