So thing is, Oc is will surely fight in great war and i said before, Lucifer don't hate him, He loves him like a father, And He is hated by other of family, So he is too close to his father and When bibical god will kill lucifer.
Oc will explode and kill bibical god and Before dying god will curse him.
Then he will stay in underworld for some decades as new ruler and then due to curse he will die and Only his wife/girlfriend will know about this
And Albion will be with him, He will be reborned as Vali.
Albion will not have any hosts for like centuries, And Young ones will start believing that white dragon is just a myth.
After getting reborn, For first few years OC will not have his memoris until he awakes albion
Then he will make his way to get his fame as heavenly dragon by staying anonymous, Not revealing truth till he can.
So what do you think now
