the thing is that they said all the vamps are dead... maybe they could place blade 4 like 25 years in the future and have one of the familiars research and reincarnate another god... i mean drake and la magra cant be the only gods... also they could make it so they raise up lucifer... thing is how is blade going to wake up... maybe half the movie is the familiars and the night stalkers trying to raise up their heroic warriors to begine a final battle
