The Leviathan's Wake

You stand at the bottom of the trench. The water is black, the pressure immense. Before you lies the skeleton of an ancient leviathan - but the skeleton is moving. The Leviathan, oldest and most powerful of all sea creatures, has been awakened by the same force that drove the dragons from their lairs and the demons from their volcano. The Fallen One's influence reaches even here. Slay The Leviathan. End the threat to the Sunken Empire. This is the hardest battle in the world.
