In the insuing battle, all lieutenants, warriors and civilians were drawn into the conflict. The Murder of Jace, The Living Guildpact shattered ravnica into two planes, the ally and enemy guilds were improsoned forever on opposite sides. The war between The Azorious and Rakdos will leave two of the elements of magic weakened. Whoever wins the war will doom Ravnica, both planes of existance, though their own doings. You must stop both sides of the war, or there shall be no winners.
