Under the Magnapuri Empire, the Sijivikh Rajdom legally encompassed the lands roundwards of the Badir Estuary, most notably the two cities of Sijivh and Badiribad. This had once been lands inhabited by the Siji and Barit wood elves, who were settled coastal peoples, reaping the rich rewards of the fertile land around the mouth of the river. Siji tribes were primarily settled in more coastal regions, while Barits mostly were found along the Badir River. Both spoke variants of the Barit tongue, which has survived in a form in the Low Magnapuri Baritani language spoken in 1181 YM, and their gods were largely absorbed into the local Gods of the Slaves. They were populous cultures, but not particularly expansionary, and quarrelled amongst themselves, and with the other nearby tribes - Ahqukh tales record both Barits and Sijis as having taken Ahquus slaves, and it is known the the Siquur Kings ruled up to the site of modern day Badiribad and had therefore conquered at least the Barit people, with some suggestion that the Sijis also paid tribute.
Dostipur had been founded a little before 500 YM, and traded with both tribes for some time - usually trading exotic manufactured goods for food and slaves. It is noted that there was a large settlement on the site of Sijivh in this time period, known as a trading hub and port town. This trading attracted greater interest in the region from the Empire, especially with the Line of Dost and Dast marrying back into the Line of Magnus, with Magna the Bloody pushing for a settlement to be built on the Roundwards bank of the Badir River in 621 YM. Initially the Magnapuri named this city Baritibad, for the people that they intended to attract to the new city for trade and a slow peaceful colonisation.
This did not go down as easily with the Barit tribes as intended, and soon there were scuffles between Barit people and the incoming Magnapuri - especially with the Magnapuri's slave races, who the Barits believed to be unnatural and disconcerting creatures. Many began to migrate towards Sijivh, causing tensions between Sijis and Barits that eventually sparked a violent revolt against the Magnapuri in Baritibad, and open warfare between Sijis and Barits in Sijivh in 628 YM. In typical fashion, Magna the Bloody responded with unreasonable and uncontrolled force, sending in her newly bred army of Orcs to attempt to quell the two peoples. Needless to say, this resulted in intense bloodshed, and the near destruction of both cities, before the Phoenix Guard had to be deployed to restore order, slaughtering surviving revolutionaries as well as the out of control Orc army. To this day this region has an unusually high population of Orcs, and a deep intolerance towards them.
Magna the Bloody promptly annexed Sijivh and declared all Barit and Siji people slaves of the Empire, and to spite the Barits, renamed Baritibad to Badiribad for the river. She appointed a Phoenix Guard known as Stormchaser who had distinguished himself in battle to be the first Raja of this new Sijivikh Rajdom of the Empire, and instructed him to bring the locals to heel. Stormchaser took for his sigil a fork of lightening over the sea, and performed admirably in bringing his new land in line with imperial standard. He moved his seat of government to Sijivh, which had been significantly less damaged in the turmoil, and set about building a floating palace and courtrooms in the bay from which to effect legal and less messy governance.
His descendants would continue to rule as Rajas even after the fall of the Empire, maintaining control of the region through the slave revolution by significantly curtailing the number of slaves, especially in more rural regions. This was largely done via widespread emancipation for fealty, and permission to practice the growing Bookburner religion as was being preached by the Masculists in nearby Salijh. Following this, the Line of Stormchaser did its best to keep its head down and avoid being a particularly favourable crusade target from the Bookburners. Though they worshipped the Gods of the Masters, they tolerated other religions and avoided provoking the Ignic Theocracy. This was made significantly easier by the nearby Magnacy of Tombranajar being significantly more of a threat and more obnoxious to the Bookburner clergy.
Thus for many years the Sijivh Rajdom survived the Fall of the Empire relatively intact. Unfortunately, this was not to last. Spurred on by republican ideals in Destrapraj, the Jisvic Hierarchy and Carabai, in 1149 YM the justices of the Floating Palace of Sijivh declared that the city would become a new merchant republic, and would no longer swear fealty to the old ways of a slavery worshipping Raja. They tried and executed Raja Thunderrumble (as he called himself - many called him Bellyrumble for his corpulence) with little fanfare, while much of his army was out of the city dealing with a border dispute lightwards with the Ahqukh Tribes. The justices declared themselves the Sijivhic Republic (using Baritani spelling, instead of the High Magnapuri Sijivikh), and held a sortition amongst themselves for Despot.
Thunderrumble's brother, a fitter and more able man named Stormbearer, who had been Thakur of Badiribad under his brother, crowned himself Raja seeking revenge and to recapture Sijivh. Meanwhile, Justicus, the first Despot, claimed all of the Rajdom for the new republic. A bloody on and off war followed, with both sides gaining or losing ground, signing a peace treaty and having a ceasefire for a couple of years before one thought it had the upper hand and started it up again. The latest peace was signed by Stormbearer and the new Despotissa, Sapphire, in 1176 YM, with Sijivh and its peninsula held by the Republic, but the rest of the region held by the Rajdom. History seems to tell that it is past time for the war to start in earnest once more, and only time will tell which side if either can emerge victorious.
