Iron Ring Atoll

It is easy not to be bothered by the noise of the Atoll if one's ears are just a pair of painted circles on a hollowed-out pumpkin.

The Iron Ring Atoll is an artificial, ring-shaped island located roughly three miles of the Coast of the Weeping Gods. it was created by the Ikona during the time of the Old Empire and initially served as an offshore harbor for the nearby city-state of Ilif. Following the advent of the synthetic Galylos River, this harbor function became less and less important and the Atoll was therefore converted into a major junction for the regional Ley line network.
The remains of the massive Cold Iron Rings, which were used to focus the energies of the Blue River into the Ley lines can still be seen in the center of the Atoll, though time, the exposure to the elements and of course the cataclysms of the Second Spring have bereft them of much of their former grandeur.
Yet while the various Rotartsnom-Arrays that used to power these rings have long since fallen silent, the deserted streets of the city itself are still filled with the sounds of grinding gears, clicking cogwheels and screeching metal, just as if the cities inhabitants were only out of town for a short trip to the mainland and could return any moment.

/* Yet while its former Empire crumbled around it, the Atoll experienced an unexpected renaissance, for its the rust-coated streets proved to be a fertile ground for the untamed Natural Energies which had been unleashed by the events of Second Spring.

History

City of Pillars and Rings

Similar to other Aineoms ("Ring Isle"), the Iron Ring Atoll was erected on top of nine enormous Cold Iron infused pillars which served as the foundation for the entire city and securely anchored the entire structure to the seafloor.
Following the conversion of the Atoll into a Ley line junction, two additional pillars were placed in the center of the Atoll, which then served as the construction site for three massive Cold Iron Rings. In addition to these Major Rings, numerous small Auxillary Rings were simultaneously constructed in the nine districts of the now mostly defunct harbor.

The Day the Clockwork Blossomed

One the day the Second Spring took place, all three of the Atoll's Iron Rings were currently undergoing maintenance given a major malfunction which took place just a single earlier. Because of this lucky coincidence, the Rings were not active when they were hit by the flood of untamed Natural Energies that had been unleashed by the Second Spring, which prevent the city from being completely leveled like many other cities that harbored Ley line junctions of similar size.
Yet while their inactive states prevented the Iron Rings from overloading and subsequently detonating, they were still highly conductive for the free-flowing natural energies, which caused them to redirect colossal amounts of untamed energies directly into the Atoll's fundament-pillars as well as the numerous Cold Iron infused structures of the harbor city.
Given that both the pillars and the city's structure housed hundreds of Adicipal-class Djins as part of an automated, internal repair system this titanic surge of wild energies caused the Djins to descent into an uncontrollable and undirected building frenzy, which caused them to randomly and indiscriminate add an uncountable amount of building compartments, ranging in size from small cogwheels and bolts all the way to entire rooms and partial buildings to the city's superstructure.
While the buildings located on the surface of the Atoll were only mildly affected by this reconstruction event, those below the surface quickly turned into inescapable mazes of stacked balconies, twisted corridors, and duplicated rooms
Despite this event only lasting for a couple of hours, it is commonly estimated that during this time the subaqueous parts of the city grew to a size more than eight times larger than their original size, though given that so far only a fraction of the Atoll's underground has been successfully mapped they could very well be even larger.

Architecture

While the Ikona were a bunch of arrogant pricks, they sure did know how to make a beautiful city.

Despite centuries of abandonment having left the Atoll's surface city in a pitiful state, the thousands of rusted iron rods and bent metal sheets that once had been masterfully folded into the city's buildings still managed to hold on to some of their long lost beauty, which enables those that possess the necessary imagination to grasp the true beauty, the city had during its prime.
Once one descends into the underbelly of the city this hint of former glory quickly fades and is replaces by an almost tangible feeling of unease and claustrophobia.

The Song of Plunder

Given the fact that the Atoll manage to survive the Second Spring, relatively intact it quickly began to attract the attention of an army of treasure hunters, scholars, and scavengers, which aimed to claim the now ownerless riches of the city.
While the buildings at the Atoll's surface have long since been picked clean of anything even remotely valuable, the underbelly of the Atoll presumably still holds more than enough treasure to turn a brave adventurer into a very rich one.

I don't know what this thing does, but I know someone that is willing to pay quite a lot for it and that is all that I need to know.

An Empty Grave

Even though the exact population numbers of the Atoll were lost during the demise of the city, it can safely be assumed that the city's inhabitant numbered in the tens of thousands, most of which presumably perished during the final day of the city.
Yet despite these sizable numbers of expected fatalities and the relatively small size of the Atoll, not a single corpse or even corpse part has been discovered so far, which naturally gave rise to dozens of tales about the supposed fate of the Atoll's inhabitants.
And with every expedition that wanders into the depths of the Atoll without finding a single piece of bone, these tales become just a little bit eerier.

Symphony in Rust

A dead city, should be silent.

While the city is long deserted, the innumerable cogs, metal rods, and branching pipes that were placed throughout it by the frenzied Djinns regularly interact with the waves, the wind and the omnipresent rain in order to create a screeching, grinding cacophony that serves as a requiem for the ruined city.
