Jagdas

Jagdas was a world inhabited by many peoples which later migrated to Rathnir. It was home to many predominantly Human nations and people before the Jagdasian Crisis, causing many of the Jagdasian refugees to migrate to Rathnir. Of the various states of Jagdas, only Yimmu-Audal migrated its entire government to Rathnir and survived as an independent state. While much of the information regarding the continents of Jagdas had been lost, a revival in research starting with the Escharian Expeditions that caused old maps to be discovered along with expeditions to explore the rest of the world.

Migration to Rathnir
The Corruption of Jagdas contributed to the migration of Jagdasian peoples to the lands of Rathnir. Many people claim that a great collapse of society occurred and that many disasters fell upon the continent. Under BlueMarble, Yimmu-Audal migrated entirely to Rathnir, keeping their name, government and traditions largely intact. Citizens of the Bimare Federation founded the Valdreach Imperial Republic. EasternKhan of the Eastern Horde settled the town of Shirûn as a successor to his Jagdasian town Maerûn. The Krobuny are also believed to have originated from Jagdas before making their way to the Maestro Peninsula.

It is also believed by some that the connection between Jagdas and Rathnir existed prior to the Corruption of Jagdas. Some academics argue that humans originated in Jagdas and began to migrate into Rathnir, displacing its native inhabitants. The suggested method of transport to Jagdas is theorized to have occurred via the End Portals littered across Rathnir, although this stands in contrast to some accounts from the era where Jagdasians still lived on Rathnir.

Location
While the theory that Jagdas lies in a dimension separate from Rathnir is commonly accepted, multiple fringe theories persist in academia, particularly in Eastern Rathnir. Some scholars from Nieden believe that Jagdas lies west of the Aurlûnor Velande. This contradicts the theories of the Elven Migrations as well as the findings of Aurlûnoren expeditions which traveled west to explore the lands across the Endless Sea.

In, the Escharian Imperial Navy under Admiral Kirvai led an expedition from Fernheim into the west of Rathnir. Upon his return in, Kirvai provided a completed map which was not recognized by academia outside of the Soleannen community. Based on Kirvai's map, the Soleannen clergy revisited the theory that Jagdas exists on the same dimension as Rathnir, further west than originally expected. Nive Pallas-Akerian claimed that Kirvai's map aligns with Aurlûnoren theories, alleging that Akan'nash and Siltor Inori are identical. It may also be possible that both theories on the location of Jagdas are not mutually exclusive, especially with regards to the discovery of Eldham to the east of Rathnir and the arrival of refugees from Kylorne.

More recent studies and research have proven that the Jagdasians headed south of their continent when they migrated, arriving from the northern Rathnir regions of Syltor, Nieden, and Plagos. In fact, the further south you head into the continent of Rathnir, the presence of Jagdasian descendants is less noticeable.
