Sword of the Gray Champion

After weakening Azazel's power by destroying the Swords of Terror, the Guardians of the Swords of Valor are looking forward to life returning to normal. That is, until their dead grandfather returns to tell them the world needs them again. The Apostles of Azazel have become the Leviathan Alliance. No longer do they need swords to dominate the world. Their plan is much more sinister, and has been millennia in the making.
Under the guidance of the quantum computer and their grandfather, the Meglio, and with the help of the Swords of Valor, they once more travel back in time, this time to consult with key figures in political history; Marcus Tullius Cicero, Benjamin Franklin, Samuel Adams, and George Orwell.
The cousins will have to be more clever, strong, and courageous than they have ever been before. They face the challenge of fighting an idea, a mere concept, battling an insidious infestation of apathy and complacency that threatens to overwhelm their world. They now face the ultimate challenge:
How can they save a world whose people have willingly given up their freedom?
