Twilight and Silence
After 900 years of glorious expansion, the Ikosian Empire realized it had run out of viable lands to conquer. To the east lay the massive, unified Grand Dynasty of Hsan. To the south was the impenetrable jungle of Koth. Overseas colonization in Blantyrre had failed horrifically, and pushing further into the hostile continent of Altazia was deemed too slow, expensive, and lacking in resources to justify further military intervention.
Stagnation and Decentralization
With no external wars to unify them, internal rot set in. The very system that fueled their rapid expansion—the House System—proved to be their fatal flaw. The Houses had grown incredibly autonomous, deeply entrenched in political backstabbing and regional control. Centralized rule fractured. While the Empire technically persisted for another half-millennium (enduring 12 dynastic changes and numerous civil wars), it bled territory.
The Five Towers Period (Altazia)
Far to the north, the Ikosian colonies in Altazia were officially abandoned by the retreating Empire. Left to their own devices, the largest of these colonies consolidated into independent city-states, marking the "Five Towers Period"—named for the massive architectural mana-gathering towers constructed over Dungeon access wells.
The Silence of the Gods (100 BC)
One hundred years before the Cataclysm, an event of unprecedented psychic and religious trauma occurred: The Silence of the Gods. Globally, and simultaneously, every single deity ceased communicating with their mortal worshippers. No miracles were granted. No prayers were answered.
The resulting hysteria shattered the spiritual foundation of the Ikosian Empire. The heavily centralized state church—already straining to mediate Imperial politics—lost all legitimacy overnight. Following 40 years of religious panic, the Empire descended into a devastating 60-year civil war. Even when a victor eventually seized the throne of Ikosia, the state was entirely exhausted, its population decimated, and its resources drained.
