An endless war rages in the heavens.
The skies blacken and crackle with dark magic. Bellows of grim laughter drown out the beating of black, leathery wings. The demons have come. Then, a ray of golden light pierces the darkness. A flight of angels arrives, swords gleaming. The champions of law have arrived to cleanse the sky. Now, planeswalker, you will wage this eternal battle between good and evil against one of your own kind. Which celestial force will prevail?
