There is very little known about the desert continent of Roven Dor but a very well known event that occurred in the 5th millennia was when a large invasion of ramshackled ships landed all along the northern shores of both Eiden and Vilea containing orc, goblins, kobolds and harpies which was an extraordinary event because these races have never been known to work together but something or someone on Rover Dor has gathered all these monstrous races together to assault the mainland. Although the assault was coordinated in landing the forces themselves did not have the leadership to successfully make any major impact to the continents but did cause some casualties for multiple farmsteads and small towns as well as a good amount of injuries and deaths to the Asari and the Ulthan Kingdoms armies in the north. With the retreat of the invasion force the Asari sent diplomats to each of the major countries and suggests a plan to send forces to Roven Dor in an attempt to quell the creatures or at least prevent another invasion from occurring. With long discussions with the leaders it was finally agreed to form a special army corp for each country whose sole objective is to create a foothold on Roven Dor and keep tabs on the creatures of the continent. A large fleet built by the Naggaroth massed around the northern mouth of the Esol Canal and transported the three massive army corps on Roven Dor, as soon as the armies landed they were met with hostile forces that did not prove to be a major threat but caused great havoc in the landing process. Once the beachhead was secured the rest of the troops and engineers formed into their corps and proceed to their predetermined destinations to construct fortresses for the armies. Over time and constant vigilance the fortresses were built and safety could be provided to the armies. Over the millennia the fortresses have been defended and in a couple of horrible cases lost but eventually regained these fortresses are the mainlands only source of information about Roven Dor.
