Kerras, The Sundered City
Kerras is split in two by the Schism, as is most of the continent. The portion on the Northeast end of The Crossing is called High Side, home of the wealthy, with the lavish estates of the Noble Quarter, the sparkling campus of the Elemental College, and the powerful brokerages of the Grant Market. Across the bridge is Low Side, home of the odorous Tanner's District, the heavily-patrolled Monument District, and the ruined area called the Tumbledown.
Kerras was most recently part of the Linaean Empire, but 50 years ago its governer declared himself Prince and Kerras an independent Principality when the capital, Linaea Imperia, fell under the onslaught of the Vadri horde.
It is, and has pretty much always been, a thriving metropolis and center of trade. It has been ruled by pretty much every major power in history.
