Boroughs Overview
Grand Convergence is divided socially into several regions called Boroughs. Boroughs are groups of Plates that are all regionally connected around a single Spire, the outer borders usually including the entire Plates that the Spires connect to as well as sometimes surrounding ones.
There are five Boroughs in Grand Convergence, each with their own culture and purpose in the city.
Bin Agal

A look into Bin Agal, the complex and twisting paths, a mix of modern built into ancient, where future and past meet and some say Grand Convergence itself turns around... This is, of course, exaggeration. If only technically.
Home to the city's council, commerce and administration, the upper district of Bin Agal and lower district of Anos form the divided heart of Grand Convergence. The lower district features some of the oldest buildings still in use, including the Grand Courthouse and Central Police. It also contains many of the city's largest temples, serving as the spiritual center for the panoply of religions practiced in GC.
Everendel

Welcome to the wild outdoors of Aurborea. Please do not feed the titanbears.
The Borough of Everendel dominates most of the outer shell of Grand Convergence. While most Districts consist of their Spire plates and the adjacent structures that remain in close contact, the domain called 'Aurborea' covers pretty much everything that isn't the mountainous region of Drakkenweald or the overgrown ruins of the Outer Lost Sector. It has the distinction of being one of the few Districts to have multiple Outer Shell spire entrances simply by default.
But Everendel is not just riotous life and invasive flora. Several civilizations make this sweeping landscape their home, from the medical genius of the Everen to the diligent hive-works of the Apiax. The Borough itself stands as a statement about the value of the wilderness and how to harness that vibrant life to bring about positive ends.
Drasin
Overview

You can find a deal anywhere in Drasin if you know where to look.
The tri-part borough of Drasin is a study in change, adaptation and survival. Above, the mountain palaces and fastidiously carved and cultivated floating islands of Drakkenweald form glamorous, intimidating jewels that flicker and blaze atop Grand Convergence. Deep below, the crumbling technogothic sprawl teems with the machinations of the clever, the desperate and the well connected. Charnel is a place where the 'Architects' are whispered amongst the people as a ward and a curse. Between them, the vibrant and flourishing artisan and trade districts of Drasin, bursting at every seam with magitek wonders and services catering to needs from the basic to the obscenely decadent.
Delerath

A view of one of the many industrial stacks of Delerath. The sounds of industry ring from them at all hours.
Overview
The borough of Delerath is the industrial titan of GC, densely packed with machines and buildings but the most sparsely populated in terms of people. Much of that population are Apiax or robots, including golems, automations and sapient machines. Delerath is the beating heart of industry, vital to the survival of GC and containing all of its power generation, local manufacturing and recycling.
While Drasin deals in the work of artisans, Delerath concerns itself with general technology, infrastructure and heavy fabrication. This is where ore is smelted and metal hammered out, where vehicles and durable goods are constructed to be shipped throughout GC and even out to other Worlds.
Far below, the District of Istamnir gleams, sending power throughout GC and bringing a bright, piercing light across the land. The critical research and infrastructure happens here, great conduits pulsing with energy that spreads through the Plates. Thanks to the proximity and relative plentitude of the energy here, technology and cybernetics are common, as well as other more exotic technologies.
The Lost Sector

The Red Marsh is dangerous in ways the rest of Aurborea is not. Tread carefully.
Overview
The Lost Sectors have been known by many names. Even more are being created and discarded every day. For one reason or another, they call to those who desire total freedom, and those who have nothing left.
Easy fortunes and easier deaths are found here. The black market is one of the biggest and most dangerous in GC due to the threat of Quarantine. What Charnel cannot acquire for fear of the Architects or Drasin will not acquire because of the law can sometimes be found here, or at least, a map to where it has been forgotten.
The smuggling scene is fiercely contested between multiple gangs, scavenger teams and reckless Prospectors. The word 'Spire' is a blessing, prayer and curse in the native lexicon. Extremely rapid shifts in connection have resulted in dozens of attempts to properly colonize this slice of GC. Outside of a few strange holdouts, they have more or less failed.
Yet people still cling to life here, or purposes that drive them to live. Here, amongst the shattered ruins of invasion, failed expedition and false hope is the ultimate freedom.
Although it is protected, there are no proper Spireguard. Although trade passes through the Spire, there are no GMI rules to follow. Although prism changes hands, you can never be truly sure who you are dealing with.
But there is light, food, shelter and freedom here. Music and dance. Secrets, danger and emotion mix freely in a heady cocktail. And a gentle voice remains ever present over the comms field, whispering that life can be good here.. even when it is terrible.
Yet, for all it's comfort, perhaps it is wise not to listen for too long.
