- The Crown Heights (Upper City): Glass towers, luxury apartments, corporate headquarters. Vampire Invictus territory. Clean, controlled, and utterly ruthless beneath the polished surface. The Spiral's influence is carefully managed here—wards and engineering marvels keep manifestations contained.
- The Academic Quarter (Upper-Middle City): Universities, libraries, research facilities. Here the Spiral is studied. Mortal scholars and supernatural beings mix in uneasy cooperation. The mortal faction's headquarters resides here, occupying neutral ground between territories.
- The Manufactured Districts (Middle City): Factories, workshops, residential blocks for workers. Vampire Carthians hold sway here, alongside Changeling Spring Court artists and makers. The Spiral manifests in strange ways—machines that work better than they should, art that moves when you're not looking.
- The Markets (Middle-Lower City): Commerce, legal and otherwise. Every supernatural Venue meets here to trade. Goblin markets hide in plain sight among regular stalls. This is where information flows and deals get made.
- The Deep Reaches (Lower City): Forgotten levels, abandoned infrastructure, sealed sections. Here the Spiral runs wild. Reality gets thin. Smart people don't go to the Deep Reaches alone—but the desperate, the curious, and the predatory all have their reasons.
Tessarion rises from the coast in impossible layers—a city built upward through generations of engineering ambition. The lowest levels date back centuries, their architecture ancient and mysterious. The highest reaches gleam with modern materials and cutting-edge design. Between them lie dozens of districts, each with its own character, connected by a dizzying network of bridges, lifts, and aerial trams.
The city's population skews young, educated, and ambitious. Universities, research institutes, and engineering firms drive the economy. The wealthy live in penthouses with literal clouds beneath their windows. The working class occupies middle levels where sunlight is filtered through the structures above. The poor and forgotten inhabit the Deep Reaches—lower levels where even the city's mapmakers have given up.
