The end of the world will not just happen, it will be a sequence of critical, well-planned events since the beginning of time.
When the fallen angels were banished from the Heavens, the celestial police force, which were formed immediately after the war told Lucifer if the fallen angels could get a certain girl pregnant by the glare of the blue moon, and this boy-child grows to maturity, survived until the age of twenty-five years, the fallen ones could come back home.
That boy-child is Lucias, the salvation of all fallen angels.
He is the key to getting them back home.
However, Lucifer has other plans for Lucias and will use him in a sequence of events to destroy man and woman, and ultimately give him the power he has desired since the beginning of time.
The war, which started in the Heavens, never ended, it only continued on earth.
