The Holy Ordean Empire ushered in a new era of civilization for humankind. Merchant Barons rose in prominence and an age of trade and prosperity ensued. It peacefully co-existed with the Muaryians during the overthrow of Razen, the despotic Munkathan King, which preceded the emergence of the Empire of Mu. The Holy Ordean Empire lasted for almost two centuries. Having never married, Astera appointed her consorts and eldest son to rule as the empire’s potentates. The true political power, however, vested in the Ordean Ruling Council, which was controlled by the Vitaras or city leaders of Lagos, Helios, and Vedic Noir.
Historians argue the decline began with the death of its founding Empress and the abrogation of control to the provincial potentates. As time passed, and the potentates became insular and squabbled. Finally, it was only the superior might of the Imperial Navy and the sea trade it protected that united the Empire.
It was the Illanthaen arrival, led by an armada of refugees that led to the empire's ultimate demise. In a climactic battle fought at Termanin Sound, the Illanthean High Seas Fleet defeated the Ordean Imperial Navy. Its power base vanquished, the Holy Ordean Empire collapsed leaving ancient Tahkt as the only remnant of the Empire. Factional wars, pirate raids, and pillaging descended Tahkt into an unruly realm. The three independent city-states of Lagos, Helios, and Vedic Noir remained the only bastions of law and order.
