The Orzhov Syndicate
The Orzhov Syndicate is the Ravnican guild of business, where the values of white and black meet and the dead exist solely to rule. Nearly every business in Ravnica ties back to the Orzhov in some way or another. While they bear the facade of a religious group and may have been a true faith at the signing of the Guildpact, they now worship only profit and power.
The Orzhov guild is founded on the beliefs that wealth is power, that structure breeds wealth, and that guilt creates structure. The guild is a combination of a religion, credit-lending agency, and crime syndicate. An ostentatious hierarchy of priests, enforcers, and ghostly councilors rules over a congregation of guilt-bound loyalists, indebted ghosts, and thrull servants. Should somebody be in debt to them, that person must work off their debt even beyond death. Many Orzhov guild members believe that their actions are necessary for making Ravnica the best it can be, and they are unscrupulous in their methods of seizing power. Most Ravnicans see the Orzhov as a corrupt organization, but many are attracted by promises of wealth, prestige, and longevity.
Their white flavor is exemplified by how they have a strong sense of tradition and community, reflected by the fact that they still partake in all of their ancient rituals and customs despite not worshiping any gods. It is also symbolized in how they hoard their wealth, but are shown to share with family members or close friends. Their black flavor can be seen in that they regularly deal with the dead, they never give to charity if they can help it, and continually violate the spirit of the law merely to meet their own ends.The Orzhov know also how to create thrulls out of remnants of past debtors.
Guild Leader: The Obzedat, the Ghost Council
The Orzhov guild is ruled by the Obzedat, a council of ghostly autocrats who have maintained their wealth and power even as they've shed their mortal forms. Members of the Obzedat are called the Deathless, as they have managed to cheat mortality, maintaining their consciousness (and their greed) beyond the threshold of death. Most of the Deathless appear as morbidly obese high priests or nobles, but sickly, pale, and ghostly in form. They are as paranoid and spiteful as dictators, often going out of their way to thwart ambitious underlings, crush rumormongers, and spy on potential enemies. They crave wealth, respect, and loyalty. The Obzedat rarely speak directly with those outside the guild; instead, they communicate through the official Grand Envoy, Teysa Karlov.
Guild Champion: Teysa, Grand Envoy of the Obzedat
The greedy, patriarchal ghosts of the Obzedat and the bickering leaders of the various cartels tend to be poor spokespeople for the Orzhov Syndicate. The human Teysa Karlov has taken a special, unprecedented position called "Grand Envoy," serving as the official speaker and ambassador for the members of the Obzedat ghost council. Once an advokist and lawmage who was instrumental in forging the current wording of the Guildpact, Teysa is now of middle age, her youthful resourcefulness streaked with wisdom and perspective. She has grown into her ambition well; her unique position allows her not only to express the will of the Deathless, but also to mold policy for her guild. While Teysa is not the official ruler of the guild, (the Obzedat still holds that position), many believe that to cross Teysa is to cross the entire Syndicate.
Hierarchy
The Syndicate used to be presided over by a council of ghosts, the Obzedat, in Orzhova, the Church of Deals. Below the obzedat stood the olicharchs, elite families who have belonged to the Orzhov for generations, and the pontiffs (executive managers). Ministrants are the priests and practitioners of Orzhov's religion. This is the highest position anyone can hope to obtain without being born within the guild. On the same level stand the knights. who provide the muscle for collecting money on time and in an orderly fashion. The lowermost position in the guild is taken by the syndics (attorneys, advisors, accountants, couriers etc.). Borrowers are not part of the guild, but they can't escape their debt even after their death.

The Cartels
Reporting to the Obzedat is a web of competing cartels, which are the individually operating units of the Orzhov Syndicate. Each cartel claims different territories and markets across Ravnica, and each has its own internal hierarchy of priests, advokists (lawmages), enforcers, and others. Each cartel is ruled by a cardinal or kingpin whose role is somewhere between gang leader, bank manager, and high priest.
Even the darkest corners of Ravnica still lie in the shadow of the Church
Long lived
The high-ranking members of the Orzhov use magical means to extend their lives, but are mutated in many ways that they pass on to their offspring. For example, one of Teysa Karlov's legs is practically useless, and therefore she has been forced to use a walking cane since she learned to walk. Members of the Obzedat were called the Deathless, as they had managed to cheat mortality, maintaining their consciousness (and their greed) beyond the threshold of death. Most of the Deathless appeared as morbidly obese high priests or nobles, but sickly, pale, and ghostly in form. They craved wealth, respect, and loyalty.
Under the influence of Bolas
To boost their declining profits in an unstable economy, the Orzhov have begun offering "protection services", promising to shield their customers both from physical harm and fiscal disaster, with the underlying threat that those who refuse to pay will become targets of Orzhov's own thugs and enforcers. Lately, the planeswalker Kaya has taken control as guildmaster of Orzhov after taking down the Obzedat. She has done this at the behest of Nicol Bolas, in exchange for him helping her "troubled family". Despite Teysa warning against it, Kaya has been freeing people from the debt they owe the guild, particularly the bound ghosts.
