Ravnica

Welcome to Ravnica, City of Guilds, a worldwide cityscape; an ecumenopolis consisting of a patchwork of grand halls, decrepit slums, and ancient ruins, with layer upon layer of stonework. Law magic and the metaphysics of hierarchy are deeply woven into the very fabric of the plane, enabling cooperating leaders to achieve feats of greatness.

Of the world's countless civic centers, one looms large above all others: the City of Ravnica, a metropolis so vast that its name has long since become synonymous with the entire plane. Centuries of Ravnican business — powered in many cases by Izzet boilerworks and other guilds’ foundries — have saturated Ravnica’s atmosphere with all manner of industrial pollution. Prior to the events of this campaign, the city and plane of Ravnica had been ruled by the Ravnican guilds and governed by the Guildpact for more than ten millennia.

Our story begins 9,999 years after the signing of the magical Guildpact, the city is abuzz with excitement and preparation for the decamillennial celebrations and festivals. Pushing their way through the bustling crowds, a grey haired man, dark of skin, wearing an official looking suit of armor, leads a ragtag group of detainees through the Tin Street Market...

Story Overview
Ravnica is a three act story, telling a story of mystery and fantasy against an urban backdrop. The adventure's plot can be summarized as follows:
 * Though many excitedly prepare for the Decamillenium, the powers that be both within the guilds and without secretly plot to tip the scales of balance in their favor. Though sporadic clashes between guilds have always occurred, acts of terrorism and open warfare have become commonplace. The adventurers can choose to ally themselves with any of the ten guilds, or none at all, discovering a plot to disrupt the Guildpact.
 * Not all of Ravnica's citizens are a member of a guild; the vast majority have no attachment. However, the guilds are a required part of daily life, and their presence is felt everywhere on Ravnica. Adventurers may choose to embrace this, gaining fame and notoriety, rising through the ranks to eventually become their guild's champion or leader. Oppositely, they may choose to forsake all affiliation, and even tear the guilds down themselves.

Story Outline
Ravnica is separated into three major eras: the story of the Guildpact, the Dragon's Maze, and the War of the Spark.
