History

Founding and the Maze economy

Thunder City was created in the era of Lin Te Aisaike, while its surrounding estates were won through fighting the Lizardmen of the swamps. The Andes Family is credited with turning that inherited foundation into a great city. 11 182

Its defining early industry was the Maze: the “dungeon” drew thousands of young adventurers seeking treasure, faith, glory, ascension, or Saint Siss’s favor. When Grand Duke Campbell defeated the Demon Lord, dungeon commissions abruptly declined, leaving many adventurers unemployed and politically volatile. 11

The city welcomed Grand Duke Campbell’s return, but Mayor Mill privately resented Campbell rule and mourned the more independent Isaac-era past. The City Council’s consultation on a commercial-tax increase was largely performative, accepting opinions on wording rather than substance. 11

Demon Lord influence

Chaos corruption and rumors of undead activity unsettled the city, though Sheriff A De Lai dismissed an early report involving apparent undead as a minor matter. 56

Princess Erin Campbell’s arrival later stabilized public sentiment during successive Chaos incidents. At the same time, the Demon Lord’s agents and economic influence had already penetrated the city; the reopening of Mist Town increased adventurer income, and Leon judged Thunder City’s populace to be deeply compromised by direct and indirect benefits. 177 184

Leon subsequently entered the city under the identity of Imperial noble Roxsey Colin. His apparent wealth, overseas connections, and luxury goods rapidly won attention among both the elite and the general public. 186 190

Industrial transformation

Under Grand Duke Edward, Thunder City developed at a rapid pace. Its industrial districts expanded around textile mills, steam-boiler production, banks, and transport infrastructure, while refugees and former rural workers supplied much of the new labor force. 186 226 479

The city experienced sharp inequality during this transition. Factory owners such as Horace exploited desperate workers and refugees for cheap labor, while Empress Street’s wealthy residents spent lavishly on imported luxuries, hotels, watches, and branded mattresses. 190 226

Later reforms and growth improved conditions for many residents. Serfdom was abolished, dockworkers’ wages increased, and workers gained access to parks, theatre performances, and a wider consumer economy. 600

Economy and infrastructure

Trade and finance

• The city’s port links it to the Vortex Sea trade network and overseas markets. Merchant interest in the Gana Continent and the Gustav United Kingdom became a major source of speculation and investment. 477 487
• The Andes Bank finances importers and cargo owners, including transactions routed directly into Wind Howl Tribe accounts. 487
• Thunder City uses Gold Coins, Silver Coins, and the newer Silver Pound. The Silver Pound gained public trust after merchants observed major holders depositing Imperial Silver Coins with Andes Bank. 487
• The Silver Pound helped protect the Campbell Principality from the Imperial currency system’s economic drain. 600
• Colin Mining Company shares triggered a speculative boom, rising from 10 to 13 Gold Coins in a single day before Leon manipulated the market through Jack. 203

Manufacturing and labor

• The industrial district produces steam boilers used on Vortex Sea ships and reportedly on distant front lines. 186
• Horace Textile Factory became a major employer, eventually expanding its facilities, hiring refugees, and participating in city politics. 504
• The Invincible Group’s construction crews became known for extreme productivity, using disguised “Imposters” and player-led organization to complete projects at unprecedented speed. 479
• Technology from North Peak City and the Great Cemetery—including tractors, tank components, and industrial methods—was exported into Thunder City through player channels and private investment. 480 543

Transportation and public works

• The Campbell Royal Railway Company was established to connect Thunder City’s port with seventeen towns and Baron Territories across the principality. 500
• Thunder City later gained public steam locomotives, bicycles, cast-iron street lamps, asphalt roads, and rail infrastructure. 577
• The airship Truth arrived carrying Academy League students, becoming a visible symbol of the city’s technological ambitions. 577
• By the start of the Os Calendar year 1054, the city’s fire department remained dependent on civilian assistance and lagged behind newer firefighting organizations elsewhere. 504
• Thunder City’s drainage system, attributed to Lin Te Aisaike, is one of its longstanding advantages over comparable urban neighborhoods. 327

Government and society

• Thunder City is governed under the Campbell ruling family, with Grand Duke Edward directing major economic, military, and development policy. 485 660
• Its City Council originated from guild institutions and is portrayed as less established than Roland City’s Three Estates Council. 504 531
• New councilors include industrialists such as Horace, who helped divide Bill No. 6 into the Factory Law and the Work Injury Insurance Law. 504
• The city attracts refugees, laborers, merchants, nobles, industrialists, pirates, and swindlers from across the Vortex Sea coast. 577
• Security worsened after the curfew was lifted; the City Guard received newer equipment as crime and migration increased. 577
• Thunder City retains prejudice against Demonkin and mixed-blood Demonkin, who face racial segregation or worse under surface rule. 184

Culture

• Thunder City residents avidly follow consumer trends, stock prices, theatre, newspapers, fashion, and imported goods. 190 203 608
• The Colin Grand Theatre and Iris Troupe’s production of Bell became a citywide phenomenon, inspiring overnight ticket queues and public discussion of love, class, and feudalism. 530 542
• The city’s growing scientific culture encouraged residents to interpret the arrival of an airship as an invention of Thunder City University rather than a divine event. 577
• Fashion magazines, department stores, libraries, the planned Great Library, and an Encyclopedia project emerged alongside industrial growth. 576 608
