Nephilim

After the destruction of the Guardian, Austin Walden and Emily Parsons are thrown back to 4000 BC. There, they make an uneasy alliance with the Almighty to assist Him with several Biblical events: Noah's Ark, battling the Nephilim, helping Moses and the Israelites, and facing Og in one last conflict. Along the way, the time travelers are trapped in Hell and other ethereal realms, as they witness firsthand God's wrath as He finds disappointment in mankind and must decide the world's fate during the Age of Giants.
