Azorius Senate

The Azorius Senate's ultimate goal is the perfection of society. They want to protect the people of Ravnica and foster a community of peace and harmony. A society's values, they contend, are reflected in the laws it creates. Something is good if it is lawful. To the Azorius, the highest virtue is a society built on stability and order, and the guild's elaborate system of laws is structured to prevent wrongdoing first and foremost, even at the expense of certain liberties. The Azorius can act as a benevolent proactive force that keeps evildoers in check, but it can also act as an oppressive bureaucratic force that stifles freedom and expression.
In the absence of the Living Guildpact, the Azorius are uncertain who is supposed to maintain balance among the guilds. As a group, they are convinced that the system can't be disrupted, but they are challenged by the reality that the one person who is meant to hold their world together never seems to be around. The Azorius Senate is invoking emergency powers with increasing frequency, and the Lyev Column's enforcers are wielding an ever-growing amount of influence.
The Azorius guild embraces the belief that Ravnican society has come too far to succumb to chaos. Civilization can be saved only through the guidance of a strong, safety-focused government. In the mind of the Azorius, the threat of chaos is imminent. They believe it is time to face facts and do whatever is necessary to protect the people and preserve the force of law.
The Azorius, as always, see agents of disorder as their greatest enemies. They have cracked down on the Gruul Clans and imposed a variety of creatively written laws outlawing that guild's presence in as many public places as possible. The Azorius also abhor the satirical shows of the Rakdos (in part because the Azorius are frequently ridiculed by Rakdos performers) and attempt to curb them with new decrees about public performances. In response to attempts by other guilds to edge their way around the system, the Azorius routinely laws to support or countermand old ones.

The Lyev Column enforces the law as Ravnica's police force. The many-leveled hierarchy of the Lyev Column includes arresters, investigators, officers, and lawmages. The Lyev Column is also venturing into the work of managing surveillance and precognition. Most adventuring characters, by their nature and because of their capabilities, are associated with the active work of the Lyev Column rather than the behind-the-scenes activity of the other columns.

As far as the Azorius a re concerned, every other guild in Ravnica is hastening along the road to anarchy. Even other guilds that are inclined toward order (such as the Boros, Orzhov, and Selesnya) are ignoring or exploiting the law.
You participate in missions to thwart the criminals of other guilds, from overzealous Boros vigilantes to insidious Golgari assassins. Dimir spies, Orzhov extortionists, and bloodthirsty Rakdos performers keep Azorius peacekeepers busy enough, without the added complications of reckless Izzet and Simic experiments putting the citizenry in danger.
Of course, whenever the members of another guild decide to operate within the law, they are potential allies for the Azorius. Even some members of the Cult of Rakdos can be pragmatic enough to stifle their impulses for a time in order to join forces against a common enemy.
