The City or just the The Megalopolis is a major urban area of Gimel.US, though it doesn't have an official name.
At the second year it already had a population of roughly 50 million (something around the half of the North-American survivors). The city grew rapidly, with new stores and skyscrapers every day, so bright yellow construction equipment and the gold-tinted windows of skyscrapers dominate the skyline, despite the implications attached to that color from Gold Morning. It took half a day to get from the west end to the east end of the City, and three quarters of a day to get from the southwest end to the northeast.
The strung-out nature of the City led to a new nomenclature - strips of development that ran east-west were called "spans", those that ran north-south were called "stretches", those that didn't run in a cardinal direction lacked these descriptors. Regardless, regions were usually named after whatever settlement was in the equivalent area on Bet, although there was sometimes conflict over what to name them after.
Streets and parks of city are filled with numerous memorial pillars, honoring lives lost during Scion's rampage. Due to lack of city planning road traffic is quite bad.
Although refugees lack a proper government, there was mention of a Mayor and city council, as well as functioning, although understaffed on periphery, police force.
The inner, urbanized parts of the city had standardized rents, but not the sprawl, which was mostly farms and tent cities. Distinction between urban centers and rural periphery is somewhat blurry — need for proper housing is still high, so people settle in apartments instead of private houses even in "rural" areas.
Two years after Gold Morning, large sections of the city were still without power routinely at night. As such, candles returned to widespread usage as light sources, and were presumably a sound economic investment.
The dominant currency in the City is the Trading Dollar, which was set up by the Number Man. A separate currency, the New Dollar, is also in use in some parts of the City, but has decreased in value.
It took half a day to get from the west end to the east end of the City, and three quarters of a day to get from the southwest end to the northeast.
The main highway going through the City ran east-west, from the city center to the Brockton Bay and Boston area. It was used by construction workers going to the city center and farm produce going from the farming areas to the east.
The Fallen camp was located west of the Boston and New Brockton districts, and south of the Meridian stretch. There was a major highway leading west from the Miridian stretch to Boston.
The neighbourhood Fenway Station was named after Fenway Station, a portal and train station located there.
The closest other portal to Fenway Station Station is the one in Brockton Bay, a fair distance away.
Norwalk station is located in Kenzie's neighbourhood where she lived with her parents.
90% of Breakthrough's activities took place in the span running from Norwalk in the west and Bridgeport to the east.
New York was the central hub because it was the place with the densest cluster of portals. 
Advance Guard chased criminals east down Post st. to Westport Stretch.
Dauntless appeared in the Northeast end of the city and rendered much of that end uninhabitable.
The Boston area sprung from several clusters where Boston used to be, south of New Brockton.
The Norwalk-Fairfield span is close to the portal for Earth N.
It is an active port, filled with heavy industry and crowded to the point of barely being contained by surrounding geography. The buildings are abundantly decorated with murals, many of them are nature themed.
New Brockton is noticeably haunted by the ghost of old Brockton Bay: some of city layout is directly copied (Towers, Downtown, Lord Street); and while current New Brockton is evading socioeconomic instability, which is rising in the greater megapolis, it is unknown if success is going to last long-term or the economic demise of the old city will repeat itself.
It is more of a district of the megalopolis, than independent city. The resemblance to old Boston is mostly cosmetic, with common to megalopolis early housing being decorated with brownstone and brick. Although calling the area "New Boston" is still unpopular.
In contrast, Boston cape scene mostly consist of independent individuals as Wardens influence did not spread there yet.
Connections and some degree of trade with other parallel Earths were established. Earth Cheit started providing prefab construction supplies and workforce, Shin - intermediary materials, and corner worlds as Earth N were tapped for their raw materials.
There was a immense and unparalleled construction boom, though for some reason it was made gold.
Long-standing tension produced by the infamous Fallen sect eventually boiled over into violent conflict, which culminated in the sabotage of existing multidimensional portals by unknown conspirators.
This incident added another critical strain to The City, increasing cases of riots and looting.
Blocks near portals are getting abandoned. Cell coverage and blackouts are getting worse, main roads are disrupted.
Jeanne Wynn of Mortari intends to assume a leadership position over The City, once all other competitors drop from the race. She eventually succeeded in the election and may use it as a stepping stone to greater positions of political power.
Refugee processing station suffered from open paramilitary attack, resulting in a heavy loss of lives among volunteers and refugees. According to Defiant and Dragon at this point the City was under constant, covert assault from Earth Cheit and Teacher agents.
Contessa made a mistake, dooming The City. Around three-fifths of the city were consumed by the dimensional rift. Luckily, at that point the evacuation of The City was mostly finished, leaving only tens of thousands stragglers.
Abandoned blocks of the City became a playground for Titans and a war-zone for capes and civilians.
↑Five thousand, two hundred and twelve parahumans had attended the final confrontation against Scion. Two-thirds of them had survived, [...] Of those two-thirds, roughly half had remained in Earth Gimel, stretched out over an area ranging from Maine to Boston to the old New York. Forty percent of those capes were heroes or something close enough to count, and eighty percent of the remainder had scaled down, retired, shifted priorities or sought lower-profile hero work, at least in the short term. - Excerpt from Interlude 14.z II
↑We’d bled into the areas surrounding the portals. Brockton Bay had been the first, but we’d had a few in a few major cities and New York was a big one. The cluster of settlements around the portals in the northeastern US and people’s desire to have ready access to that cluster and the resources, community, information and security it afforded had played a big part in the megalopolis forming.
One blob around New York, one blob around the New Brockton settlement, clusters south of New Brockton, near what would or should be Boston, and everything had spread out or extended from there, mostly hugging the coast and connecting to one another. - Excerpt from Daybreak 1.2
↑Gimel has five major points of settlement, with civilization finding its foothold around these points. The City, as of yet unnamed, is the primary US point of settlement and one of the primary waypoints. The City is a megalopolis with a commonly cited population of fifty million. - Glow-worm P.6
↑Of the five people contending for mayorship over the city, where roughly half of the North American survivors of Gold Morning were staying, he polled in fourth place. - Excerpt from ShadowInterlude 5x II
↑ 5.05.15.2[A18 11:11:47] Moonsong: And your family? Your parents? I liked them when I saw them.
[A18 11:12:00] Cap: alive. we’re in the city. they’re trying to come to terms with things [A18 11:12:35] Cap: things are really coming together like crazy. new skyscrapers every day, new stores. good and almost like a city in Earth Bet but it isn’t really home [A18 11:15:08] Moonsong: It isn’t. We’re in the city too. [A18 11:16:17] Cap: You and your folks? they’reokay? [A18 11:17:40] Moonsong: They’re good. Dad is taking a shot at mayor or councilman. We’ll see what happens - Glow-worm P.2
↑The skyline was a half-and-half mix of skyscrapers and buildings in progress. The latter were skeletons of tall buildings in the process of being filled in and put together, and hazard signs, tarps, the materials that made up the countless cranes and the painted letters on steel girders were all in bright yellows. The completed skyscrapers were paneled with mirrored or reflective glass that were tinted in that same hue. All put together, the light that bounced off of the city and reached skyward gave the clouds linings that were gold, not silver. - Excerpt from Daybreak 1.1
↑ 7.07.17.2The city was so vast it took half a day to get from the west end to the east end. Three quarters of a day to get from the southwest to the northeast, though the Dauntless Titan had kind of trashed the Northeast by appearing there, so it wasn’t a real consideration. - excerpt from From Within 16.2
↑“In terms of the bands that rope everything in together, we go by the cities and locations that were there beforehand. If you look at where Norwalk would be on a map, that’s the name for the region we’re heading to. If it’s east-west it’s a span. If it’s north-south it’s a stretch. But it’s all a part of the city.”
“What if it’s both?” someone asked.
“Then it’s neither,” Jasper said. “You just give it a name.”
“More accurately, you try to give it a name and end up in a heated, months-long debate about what to call the area, with way too many emotions tied up into things,” I said. - excerpt from Daybreak 1.2
↑We have no authorities. We have no system of government. We have no national cape team or licensed heroes. We can’t even agree on a name for Gimel’s megalopolis! - Glow-worm P.8
↑► Venturain Replied on August 22nd, Y1: the corner world places aren’t inherently bad tho, right? we (my family) just got into the city one month ago. right away pressure pressure. we can move into city but standardized rent and we need to earn wage and we may be asked to move. best option is to move to city periphery and farm. they say they will give us tools and resources to get started but good spots are taken or very far away and farming isn’t easy
corner worlds are closer in a way. go to noon, go to wherever from there.
if we aren’t reconstruction or farming we aren’t wanted. so why become cogs in the city’s machine? we can strike off on our own. minor risk but total freedom - Excerpt from Glow-worm P.6
↑We’ve got these long narrow bands of mingled city and agriculture connecting the primary settlement points, to the point it’s hard to say where one thing starts and the other ends. And instead of building five big houses they’d rather build an apartment building that hosts twenty, which makes things fuzzy with the distinctions of urban and rural. - Excerpt from Daybreak 1.2
↑So many things were reliant on resources. Money- they handled money and they had money. Kurt had arranged the trading dollar and he’d made it work. A city couldn’t run on barter, and a megalopolis was far more involved than a city. - Excerpt from Interlude 5x II
↑“I wasn’t happy about it being New Dollars,” Durbin volunteered. “She was nice about giving me more when the value dropped.”
Anelace nodded, looking at me. Unconventional currency for the unconventional settlement of Wailings. The Trading Dollar was the dominant currency across the Megalopolis. Other currencies were tied to natural resources, to other Earth currencies, but they had their issues. The New Dollar had its issues, but it was still used in places, on the fringes. - Excerpt from Torch 7.6
↑ 17.017.117.2Curious_Cephalopod: …the problem is we’re so geographically spread out. even if we discount R.
of5: I’m aiming to move into the city. There are complications - Glow-worm P.6
↑ 18.018.1Curious_Cephalopod: ? Did you disconnect? Heart_Shaped_Pupil: So I was thinking we should meet in the city. You were talking about logistics and I was thinking about where eveyrone was. you’re closest to me and we’re the same age I think? - Glow-worm P.6
↑Stratford station and the surrounding neighborhood were an area of the megalopolis I primarily knew for its airfield. Helicopters were in and out, and as someone who often had to fly past, I had to be mindful of the airspace. I usually flew low or gave it a wider berth, using the highway to the north as my guide.
Now that I was in the neighborhood and moving at a walking pace, I could see it was one of the quainter areas. It was one of the first areas to be settled, and the buildings were smaller, with more houses. Not too dissimilar to my mom’s neighborhood. Even the apartment buildings were three or four floors tall at the highest. Like many of the buildings in the early settlements, they’d been built broad rather than tall. - Excerpt from Shadow 5.6
↑I have access through the portal at the east of the city. When I go through I’ve been doing loops through the old neighborhoods to see what I can scrounge up. - Excerpt from Glow-worm P.1
↑“I’m thinking about the prison,” Tristan said. He stabbed a marker at the series of squares and lines that depicted the prison. “To get there, you have to travel to one portal, which is about twenty-five minutes away from the city, and then you have to travel for another twenty minutes to get to the next portal. That one’s where the guards and security are. That’s without the time it takes to reach the first portal. It’s deliberately set out of reach. What are our options?” - Beacon 8.7
↑The road was fairly busy. The timing of our trip meant we were traveling down the main East-West highway that ran through the city, and it seemed like a lot of the farming settlements were transporting stock out to the east, traveling in the direction of the Brockton Bay and Boston areas of the sprawl. That procession was compounded by the stream of construction vehicles heading toward the city center. - excerpt from Torch 7.3
↑“Standoff with the remaining Mathers Fallen and Narwhal,” I said. I assessed the situation. “I think Narwhal has it handled.”
“I’d think so. I’ve found the Crowleys, they covered their retreat, and now they’re on the move. They borrowed a fleet of cars from a town north of here, and they’re heading east.”
“East? Boston? New Brockton?”
“I’m betting the Boston district of the Megalopolis,” she said. “They’re taking a route using roads that are barely roads, they’re so rustic. If you take the major highway, you could get ahead of them with time to spare. Give me what I need and we’ll help.”
If this is to be believed, the Fallen went north, to the Meridian stretch, and then they’ll go east. - excerpt from Pitch 6.6
↑New Brockton felt like it sat on that brink between relevance and ruin. As a settlement, it was defined by tall buildings and the edifices of heavy industry. There were ships finding their way past each other on the water and big brick buildings with black plumes of smoke rising from their chimneys. Already back to the ways of an era that predated me, cutting corners to produce more at a cost to tomorrow. It was crowded and bursting at the seams, and it had been for a while now, trying to grow despite the constraints of water and mountain around it.
It didn’t escape me that the settlement continued to chug along while the gears and belts of the greater megalopolis were grinding to a stop under strikes and shutdowns [...] The racist graffiti no longer dominated downtown, though I did see some, with half of it partially painted over or altered. Many of the people who had lived and thrived in Brockton Bay had made their way here, after all. An attempt had been made to use wall space, to give the tenements-and-factories color when mirrored windows on skycrapers didn’t steal it from the sky or water. Murals now decorated many of the walls and building fronts, no doubt an attempt to leave less open wall space for the gang tags and symbols. Animals and symbols of humanity like clasped hands covered residential areas. Green trees, branches, and lush mountains painted almost ironically on the sides of factories and power plants.
There were places that mirrored home, in layout and the buildings that had been placed. The area that had been the Towers at the southwest corner of the city was still the Towers. Downtown was still where Downtown had been. A Lord Street stabbed north-to-south through the settlement. Despite the attempts, it wasn’t home. It came from something different. Excerpt from Glare 3.1
↑Boston. New Boston, but all attempts to make that stick had failed, in a stark contrast to how Brockton Bay had been so ready to rechristen itself as New Brockton.
Boston wasn’t a city, really. It was more of an Über-neighborhood, one set of tiles in the vast, disappearing-into-the-horizon expanse of city that was the megalopolis. It wasn’t really Boston, either. Attempts had been made to make Boston resemble its former self, but materials were different, everything was new, and the golden patina remained.
Fenway Station. A transportation hub, surrounded by quickly thrown-together homes that attempted to stay hidden or camouflaged among the brownstone and brick fixtures with gold-tinted windows.
The Boston neighorhoods had heroes of their own. Independents, and small teams separate from the Wardens. - Excerpt from Pitch 6.8
↑The government had sent people inside, and Tattletale had followed suit. It was technically her property, they had no evidence it was anything but the curiosity of an invested businessperson, and they hadn’t complained. - Excerpt from Imago 21.4
↑I had a sense of which materials had come from where, with a lot of the prefab building segments having come from Cheit, a lot of crude materials from Shin, and outright raw materials from Earth N - Excerpt from Black 13.7
↑“The second war is over the portal-wracked areas in the heart of the city. Those of you who are more used to working over there will recognize the names. Deader and Goner operate from a corner world much as we’re operating from the Bunker. Barrow is a corner world, in a manner of speaking. The Lords of the Pit have the villains of the Pitstop under their thumb. We think the best use of resources would be to put Advance Guard on this.” - Excerpt from Breaking 14.2
↑The Mayor motioned toward a screen, that same overhead view from before. Now it showed the damage that spanned three-fifths of the city, which itself more or less spanned everything between New York and Boston and New York and New Brockton Bay. Shadows from the dust that had reached the sky above the city cast it in a noticeably darker tint, as though it were night. - Excerpt from Sundown 17.z
↑“How many people are still in the city?” he asked.
“Thousands. Tens of thousands,” Citrine said, from the end of the table. - Excerpt from Sundown 17.z
↑The city was being patched together. In a way, without the civilians there, it was easier to do the necessary work. The cracks were being paved over, and where they weren’t in a position to do the paving, they had quick-deploy bridges criss-crossing over the gaps like sutures. Buildings were actively being knocked down if they were hazardous, and the ones that were stable were being supported and added to.
Here and there, there were the scavenger camps. Organized, with the option for people to buy in, quickly sell, and then walk away with cash or whatever treasure they managed to dig up. There were similar projects with tree planting, farming, and setting up houses in the corner worlds… which weren’t corners anymore. -  from Last 20.e4
