The most wide-spanning empire of Gloranthan history was the Middle Sea Empire, also called the Jrusteli Empire. Its core was city-states of the island-continent of Jrustela who were tightly allied with the kings of Seshnela, and in 789 they formed together the Middle Sea Empire.
Seshnela and Jrustela were ruled by Hrestoli Malkioni, although they had significant Theyalan influences, particularly in Jrustela. The Umathelan Coalition was part of the original alliance, and in Pamaltela, the Empire expanded to conquer Fonrit, Laskal, and Jolar (where it was known as the Six Legged Empire). Slontos was conquered by the Middle Sea Empire, and it formed a borderland between the Middle Sea Empire and the krjalki of the Empire of the Wyrms Friends, with its dragons and trolls. Akem in Fronela was also a stronghold of the Empire, which later expanded to rule much of Frontem (Loskalm).
The Middle Sea Empire ruled Teshnos, Teleos, and Loral and included the New Dragon Ring of Kralorela. The Dark Empire of Ralios was conquered in 740, and the Arkati secrets taken from the Stygian Archons formed the basis of the Mythic Maps of the God Learners, which enabled their great conquests. The Mythic Synthesis Movement enabled the God Learners to develop the Monomyth, a holistic understanding of all the mythologies of their allies and subjects. Cults such as Chalana Arroy, Issaries, Lhankor Mhy, and Wachaza were deliberately encouraged and spread by the God Learners, although the ruling caste was largely Hrestoli Malkioni, at least at first.And this is something worth keeping in mind – the Middle Sea Empire was not a Malkioni missionary movement. Each new culture it encountered or conquered had secrets and insights which were synthesized into the Monomyth, and the God Learners came the closest of any mortals to seeing the “whole mythological picture”. Their insights were adopted by their enemies, for example, Jrusteli information and trade filtered into Dragon Pass, where it was quickly appreciated by the rulers and used in tandem with their new draconic magics.
The Middle Sea Empire was primarily a naval power, with water elemental powered battle barges and used sorcery to command the waters. On land, it was typically less effective, relying on sorcery and heavily armoured horsemen.
