Sigil, city of doors

Sigil
It’s the single largest city in the multiverse.
It’s the most corrupt and barbaric cesspool sentience has ever created.
It’s the greatest wonder on all the planes.
It’s the theorised Center of All.
It’s Sigil, city of doors.

Sigil is Sigil. Unity of rings, cutter(figures that it would be even more effective in a ring on the great ring, huh?). Though the multiverse changes around it, sometimes for good, in Sigil, no matter what, the more things change, the more they stay the same.
Firstly, the facts.
Sigil is the single largest city in all the known multiverse, with a population of well over seventy million planars, exemplars, primes, elementals, and others, spread out over a minuscule area compared to the population(roughly 1320 square kilometres, with the ring being 50 kilometres wide). It consists of ten wards: The Lady’s Ward(1>%), The Guildhall Ward(5%), The Clerk’s Ward(6%), The Business Ward(1>%), The Market Ward(9%), The Lower Ward(22%), The Upper Hive(31%), The Lower Hive(19%), The Docks(6%) and The Industrial Ward(1%).
Denoted in parenthesis is the approximate percentage of the population living in the area. In addition, quite a large amount of people(approximately 3,8 million) do not actually live in Sigil, but in large suburbs surrounding well-known portals into it(cagers have given these people the nickname “pendulums”), which they simply use when heading to work.

The Upper Hive
Situated between the Docks and Lower Ward, The Hive is a living hell for those forced to live in it(very few people would willingly even step into it). As huge gangs engage in what resembles all-out war in its alleys, paths(it has nothing worth the title of “street”), catwalks and tunnels, murderers run unchecked through the night, and thousands succumb to disease daily, most people lose what little faith in others they may once have had. This leads to even more violence, hate, and destruction. Very few people of the other wards take an interest in the goings on of the Hive Wards, except to make sure that they stay out of the lives of more “civilised” people. The only authorities to be found within the Hive are the local gang bosses, and now and then a small group from the Sons of Mercy. The latter are led by a sun elf named Woll’jyn, who is one of the few people to rise from the pit of despair that is the Hive. In appearance, the Hive resembles slums all over the planes, just in a far greater scale(and with more spikes). Buildings on top of buildings, alleys overhung with plastic tarp to help the homeless living there escape the common acidic rain, burning thrashcans(often stolen from the richer wards, due to the extreme lack of trashcans in the ward)… The Hive’s got it all, and more. However, the close proximity of the Mortuary means that surprisingly few corpses litter the paths, and the Sigil Sanitation Committee is directly funding the Dustmen to allow them to offer greater rewards to the collectors.

The Lower Hive
If the upper parts of the Hive are hell, what lies below is bad beyond description. Initially created to escape the overflowing gutters, disease, and wars that plague the Upper Hive, desperate cagers went for the last direction of escape: Downwards. There in Undersigil, they did find peace from the gangs and murderers roaming the cityscape above, but in return, they may have gotten something far, far worse. The speedily growing community attracted all manner of unsavoury beasts(who were already pretty pissed about being driven out by the subway system), who were greatly annoyed by the new presence within their hunting grounds(well, some of them were probably actually quite happy with all the fresh meat delivered at their proverbial doorstep), and took steps accordingly. Thus, most people in the Lower Hive live in a proverbial state of paranoia, and most areas have a great deal of neighbourhood protection. However, unlike most other neighbourhood protection programs, these guys carry automatic weapons, rocket launchers, and combat armour. In appearance, the Lower Hive differs somewhat from its above-ground counterpart: mainly in its lack of extreme overpopulation. In the Lower Hive, you will find no burning trashcans(as nobody’s stupid enough to sleep outside in the streets), no homeless, as there’s plenty of spare homes(mostly vacated due to the violent death of the former owner), and no corpses in the streets(as most creatures down there don’t leave behind valuable nutrition). Another thing which singles out the Lower Hive is the lack of razorvine and spikes: the entire ward is made up of the yellowish-brown bedrock of Sigil.

The Docks
The Docks are built around two large basins(well, half-basins, really), one known as the Ditch, the other known as the Pit(in fact, both used to be known as the Ditch, but more on that later). The Ditch is the cleaner of the two, but it’s still very, very dirty water there, from all the waste led into it from the Industrial ward(the Celestials aren’t very happy about that). The Pit is filled with what’s basically diluted Styx water, and industrial waste(wait, make that regular Styx water). The two basins are connected to the river Jordan and Styx respectively(accordingly, the piers surrounding the Pit is constantly searching for experienced men, as nobody remains experienced around there for long) through gigantic, eternally-open portals that Shemeska the Marauder hired an extremely skilled portal-mage to open(it’s rumoured there’s also one to the elemental plane of water, at the bottom of the Ditch) back in the dawn of time(well, nobody can remember the time before the Docks, aside from perhaps the Golden Lords and other outsiders in Sigil). Accordingly, she owns nearly all of the piers and most of the warehouses of the ward. Though she doesn’t put a toll on the use of the portals, she has close to a monopoly on trade through them, as very few captains care to swim their cargo to shore(especially in the Pit). However, some twenty years ago, Snail Outfitters managed to obtain the deed for a teeny tiny spot of land on the shore of the Ditch, and they have used this as an anchoring point for a pier of their own, along with an attached shop. It is said that when Shemeska heard of this, her wrath cost several million Torus in damages(mostly property, but also a few cases of life insurance). The Docks are dominated by large warehouses, owned by the various golden lords(and rented out to lesser merchants), each with their own highly trained and equipped security teams.

Right, so I just posted this here as a way of shouting "dibs". It's not finished yet(seven wards to go! WOO!), and I'm open to critique and suggestions(frankly, it's SIGIL. If this isn't a group effort, well, something's wrong), but I have this perverse fascination with always being first at something, so my ideas get considered first.(also, I'd hate for the official version of modern Sigil to be different from the one in my head)
