Lysunica

Lysunica is bustling megalopolis that sprawls across the inner plains of Nyr. It was once five grand estates ruled by powerful families, but centuries of growth and urban development have fused the city into one massive super-city. Once at constant war, the five houses settled their differences and drafted a document of truce sealed with powerful magic. The document became known as The Guildpact, and it prevented any one of the five houses from gaining too much power or influence, among other stipulations.

The Five Houses

 * House Azorius: House Azorius is the house most like a governmental organization and the least like a profit-earning guild. This house contains the Azorius Senate, the governing body of Lysunica, as well as the Azorius Legion, an army of disciplined warriors who police the streets of the city and defend it from invaders and thieves. Azorius' Guildmaster is Vino Velarovic, who is also the de facto ruler of Lysunica.
 * House Izzet: The House of Izzet is renowned in Nyr for their advancements in the study of man and machine. Izzet inventors craft lightning-fueled engines of power and Izzet biomancers practice esoteric magic to manipulate life itself. House Izzet's Guildmaster is Niv'Mizzet, an ancient red dragon who founded the guild centuries ago.
 * House Orzhov: The secretive guild of Orzhov manages the banks and financial institutions of Lysunica, as well as the more clandestine operations that take place in the city. Lysunicans know to always pay their debts, lest they are paid a nighttime visit from the enforcers of house Orzhov. Orzhov's Guildmaster is Tessa Karlov, a powerful necromancer with a host of undead debtors who continue to pay their balance in the afterlife.
 * House Rakdos: Filled with artists, mavericks and debauchers, House Rakdos is the least respected guild in Lysunica. House business includes writing books, producing fine arts, and putting on rousing performances for the dwellers of the city to enjoy. Rakdos also runs the many bars, taverns, and places of hospitality in Lysunica. The Guildmaster is Lazav, a former Faceless that reclaimed their identity but kept their shapeshifting ability.
 * House Selesnya: The enterprising souls of House Selesnya manage the natural spaces and food production of lysunica. A massive network of farms and ranches grow the immense amount of food needed to feed the city's ravenous hunger. House Selesnya also includes many independent guild-workers, who seek security in the house's large size. House Selesnya's Guildmaster is Trostani, a dryad triplet whose bodies and identities have fused together in old age.
