About Tyrann[]
Tyrann was the 1099th planet settled by humanity in its initial galactic expansion. A world of rocky geography and an extremely arid climate, its harsh environment shaped a tough and aggressive species of colonists. The people of Tyrann, under the absolute leadership of their ruler, the Khan, launched a swift and brutal campaign of imperialist expansion across the Nebular Kingdoms.
The Tyranni conquest was remarkably successful, subjugating nearly a hundred worlds in just fifty years. Their victory was owed almost entirely to a critical technological advantage: their ships were small, agile, and equipped with advanced automatic controls that minimized the need for human intervention and allowed for incredibly precise hyperjumps. This gave them a decisive tactical edge against the larger, more cumbersome warships fielded by planets like Rhodia, which they defeated with ease. The only notable resistance they encountered was from the commercial world of Lingane.
However, the Tyranni Empire's strength proved to be its weakness. In a catastrophic strategic error, the Tyranni fleet eventually abandoned its successful small-ship doctrine. They replaced their agile vessels with larger, more conventional battleships in an attempt to project greater power. This decision stripped them of their only major military advantage. Without their technological edge, their expansionist momentum halted almost immediately and quickly reversed into decay. The empire became overextended and vulnerable, setting the stage for its eventual collapse orchestrated through the rebellion on Rhodia.
