It is the year 2022. It has been twenty-two years since second impact. It has been six years since the UN publicly declared the NERV mission to be over, decommissioning, dismantling and mothballing its facilities, equipment. The final confrontation between the angels and NERV remains a mystery, shrouded in secrecy and buried beneath layers or redaction and Top Secret UN and NERV clearances as 'The Vanderheit Incident'. What is known is that the entirety of the Japanese Archipelago was somehow affected, leaving it a barren lifeless wasteland, and quarantined by the UN Navy.
Without the threat of the angels, the UNs grip slowly eroded on some of the more outlying and less developed territories as territorial infighting and resource competition slowly begun again. Five years ago, hostilities erupted in the Two Day War along Africa and the middle east, halting when a previously undisclosed UN weapons cache was accidentally detonated by the infighting.
Privately, the UN inner council knows that the real reason the war was interrupted was the emergence of the angel Ahkraziel from the oceans and engaging the hostiles. The emergency N2 salvo that destroyed the warring forces also destroyed Ahkraziel. With the threat of the angels again looming, resources and manpower were one again dredged up to form a functional Evangelion force.
With the increased relative power of Russia and China after the destruction of Japan, NERV began construction immediately on a new forward Evangelion base of operations along the border.
