The Over City Ruins are the abandoned urban expanse surrounding the inhabited settlements of the Third Floor. Streets, collapsed buildings, parks, and the remains of older institutions occupy most of the floor. Creatures altered by the catastrophe in the Over City's history inhabit this territory, while village guards protect only the surviving population centers during daylight. Carl, Princess Donut, and Mongo cross the ruins on their way to a skyfowl settlement and become involved with the remnants of Grimaldi's Traveling Circus. The district outside the villages is therefore both a route across the floor and the setting of encounters that change the party's available exits.
Extent and origin
The Over City is not a single inhabited municipality. Mordecai describes hundreds of villages scattered through connected tracts of abandoned city. He estimates the Third Floor at roughly 300,000 square kilometers and says that most of that area consists of ruins. The size matters to crawlers separated by the floor transition: two parties can arrive in different settlements with no practical way to reunite quickly, even if they can still exchange messages. Traveling from a starting village to a better supplied one can take a substantial part of the floor's eight-day allotment. The ruins are the intervening ground, rather than an optional site set apart from normal travel.
At the gate of Carl and Donut's starting village, the settled streets give way to crumbling, moss-covered brick buildings. Fog limits their view of the abandoned structures beyond. Mordecai identifies old buildings and overgrown parks as the ordinary terrain outside the settlements. His description ties their condition to the Over City's founding story: a civilization occupied layers within a dormant volcano until a monster's poisonous eruption killed or transformed much of its population. Descendants of survivors live in the villages; transformed creatures remain among the old streets. The ruins thus preserve the physical division produced by the disaster, although the sky and volcano setting are part of the dungeon's constructed scenario and the crawlers remain below Earth's surface.
The origin story has practical consequences in the present. Monsters are not confined to one designated arena, and some retain traces of occupations or communities that existed before the catastrophe. A crawler can enter an apparently ordinary street or building and meet something whose current behavior derives from that older city. The circus creatures, once performers, occupy several blocks as hunters and sentinels. Street Urchins, once kept to clean homes, continue to remove refuse after their transformation. These are different dangers with different responses to intruders; the condition of the city alone does not identify which creature is nearby.
The village boundary and the road north
Village gates mark a sharp limit to civic protection. The Third Floor's village guards are assigned to defend population centers from creatures roaming the Over City Ruins, but they operate only while the sun is up. Mordecai warns Carl and Donut that attacking residents or stealing from shops can bring an immediately lethal response. He also says guards will not pursue a fleeing offender into the ruins, although that crawler may then be unable to return to the village. Outside the gate, freedom from the guards' authority comes with exposure to mobs. The boundary is neither an absolute wall against monsters nor a promise that every village street remains safe after dark.
At a route marker beyond the starting village, Carl finds the medium skyfowl settlement signposted thirty-four kilometers to the north and a staircase only six kilometers away. Other arrows indicate saferooms and restrooms. The shorter route to a stairwell could take the party onward, but Mordecai directs them toward the medium settlement: it has a tutorial guild where he can meet them and shops better suited to their needs. The road across the ruins is accordingly a decision about supplies, training, experience, and time, not merely the distance to the nearest exit. The group has to make that journey while the Third Floor's collapse clock continues to run.
Saferooms and restrooms are distributed through the ruins, so Carl and Donut do not have to retreat to a village whenever they need shelter. Tutorial guilds are confined to settlements. One early refuge, the Belly-Rubbed Pug, stands at the end of a turning alley rather than on the main road. Carl, Donut, and Mongo run for it while hostile map markers gather in the nearby streets. Inside, the room resembles a tavern, with a Bopca protector and rentable sleeping rooms. Its position demonstrates the difficulty of using the floor's amenities under pressure: knowing that a saferoom exists does not make the intervening alleys safe, and reaching its door can require breaking away from pursuit.
Mordecai distinguishes daytime travel from nighttime travel before sending the party out. Ruin creatures remain active by day but become more dangerous at night. He cautions them against going out after dark until they are ready. Villages are safer in daylight, while after sunset even a village's alleys can become dangerous; their main roads offer more reliable protection. This uneven pattern makes the settled and abandoned areas parts of one changing urban landscape. A party cannot assume that crossing a gate, or remaining inside a settlement's nominal limits, settles every question of safety.
Ambushes among the abandoned buildings
The first circus-associated attack shows how the old city gives its inhabitants an advantage. A skull-faced juggling lemur appears at a second-story window and throws a knife at Carl. It does not appear on his minimap until the attack makes him aware of it. More lemurs then show themselves at windows while calls answer from farther down the streets. Carl and Donut retreat into an alley without exposed windows, but the cries indicate that the visible attackers are only part of a larger group. The encounter opens The Show Must Go On, the quest concerning the surviving circus. The ruined buildings are part of the attack: their upper floors and obscured approaches make a creature hard to spot before it strikes.
Carl, Donut, and Mongo later flee a swelling group of hostile markers toward the Belly-Rubbed Pug. Carl uses smoke and Donut's magic to create a path, but the wind shifts the smoke away from where he needs it. Their route then winds through side streets into the saferoom's dead-end alley. The episode makes the density of the ruins consequential. Streets offer room to run, yet turns, windows, and the placement of the next safe door determine whether a pursuit can be escaped. The map helps Carl choose a destination, but it does not prevent threats from appearing above street level or from converging behind the party.
On a later morning, the artificial sun casts long shadows over the wooden streets. Carl notices smoke rising from scattered places and a sulfurous, acrid smell in the air as the party resumes its journey. He checks a dungeon locator to confirm their direction toward the skyfowl settlement. The visual continuity of street after street does not give them a simple line of travel. They still need signs or the interface to orient themselves, especially after detours forced by combat and the circus quest. The visible decay and smoke also keep the catastrophe present in ordinary movement, rather than only in quest explanations.
Grimaldi's circus in the ruins
The remains of Grimaldi's Traveling Circus occupy a distinct part of the abandoned city. Juggling lemurs patrol the surrounding streets, while tents and other former attractions stand farther in. Carl approaches as the sound of a calliope grows louder. He and Donut shelter in a building overlooking the tents and worry about the approaching sunset because they have not seen another saferoom nearby. They can pick off some sentinel lemurs if they move carefully, but fighting across the perimeter costs daylight and risks drawing more of the circus toward them.
The circus's dangers reach beyond its tents. Heather, a transformed roller-skating bear, hunts mobs and crawlers and carries prey back for the clowns. Signet confronts Carl near the circus and draws him into her conflict with its infected inhabitants. The performers are bound to Grimaldi, who has become a vine within the big top; parasites and spores help sustain the cycle in which members of his circus return after death. The surrounding ruins therefore contain both roaming predators and the approaches to a long-lived, concentrated infestation. Carl's initial street fight does not reveal the full cause of the creatures' persistence.
The old structures also create hazards unrelated to an enemy's attack. When an explosive strike tears up the street near the circus, Carl, Donut, and Mongo fall into a ruined room below the main level of the city. It has stone walls, rotting barrels, and the remains of a staircase that once led upward. The opening above is their only apparent way out. Carl had not known there were rooms beneath the visible streets. This collapse exposes another layer of the urban remains and briefly turns ordinary rubble into an obstacle between the party and the surface route they had been following.
As Signet prepares her assault, Carl checks the map from the area around the circus. Hundreds of hostile markers lie at its edge, while other creatures move or wait throughout the surrounding neighborhood after dark. Signet's summoned allies are fewer than the circus inhabitants. The count explains why entering the tents requires more than defeating a few roaming monsters: a dense local population surrounds the boss, and the rest of the nocturnal ruins remain active beyond it. Carl ultimately enters the big top under circumstances shaped by Signet's attack, rather than clearing the district street by street.
Scavengers and a newly accessible exit
Street Urchins illustrate a different kind of ruin ecology. Before the catastrophe, these small nocturnal creatures were kept by wealthy residents to clean their homes. The transformed versions are larger and spikier, and their function has shifted to removing bodies and other refuse in the abandoned city. Their description warns that they usually leave others alone unless obstructed. When Carl encounters them amid wreckage, he discovers that placing pieces of debris in their path diverts them toward the material they are trying to consume. After he clears away the remaining sharp objects and rubbish around the group, the creatures lose interest. The same behavior later serves a grim civic purpose: GumGum says bodies found in the skyfowl town are piled outside its gates for the Street Urchins to remove.
The circus quest changes what Carl can see of the ruins. After the confrontation with Grimaldi and Signet, the tents and the bodies around them have vanished. A staircase to the Fourth Floor is now visible in the middle of the park. Carl observes that it had not appeared on his map before, even though other inaccessible stairways had appeared there. Mordecai explains that some exits on later floors become visible only when a quest is completed. The location of the new staircase suggests it may have been beneath Grimaldi all along, but Carl does not know that for certain. Its appearance turns the former circus ground into a usable route downward and makes the outcome of a local story materially important to travel across the floor.
