Modern Talan is not a clean slate. The kingdoms, the rail network, the dwarven script that still mortars old place-names, most of what feels timeless about the continent was built, broken, or birthed by civilisations that no longer exist as themselves. The history page tells the chronological story; this section tells the institutional story, who these civilisations were as polities, what they actually did, and what they left.
Three civilisations have earned dedicated pages so far. Others will follow as the canon makes room.
Each of the three reached a height no other civilisation of its time approached, and each one is the catalyst for the era that followed it.
The Elden ended their own era by vanishing, and the void their absence left on the Material Plane is what allowed the gods to take direct rule of mortal civilisation for the three thousand years of the Gods' Era that followed. The Storveldi Denbora (the name some chronicles attach to the disputed Old Race) ended the Gods' Era when their downfall triggered the Week of Crimson Rain, the catastrophe that broke a Grand God's invulnerability for the first and so far only time. The Golden Empire ended its own Golden Era when its late-period mining programme breached a seal older than recorded history, and the Dark Era opened on what came out.
None of the three is the calm between catastrophes. Each is, in its century, the catastrophe, and each of the modern Talanese eras is downstream of one of them. The Gods' Era from the Elden's vanishing. The Lost Era from the Crimson Rain that followed. The Adventurer Era from the binding that followed the Empire's breach. Three civilisations, three world-ages. The continent has no clean foundation; it has layers, and these three are most of what's beneath the soil.
Their fingerprints are everywhere in modern Talan. Dwarven script fossilised in your kingdom's law-books. Elden rail principles under your Magitrain. The Azarketi who claim Elden blood and run the harbour. Each line of inheritance points back to one of the three.
