Arenthian Verge

The Arenthian Verge is a swath of land in the border regions of Cyrodiil, Valenwood and Elsweyr, reaching from Anvil in the west to Rimmen in the east. It is a region independent from both the Vilpesian Empire and the Crystal Consolidate, serving as a buffer zone between the two factions in case either of them attempts to declare war. Its capital is its namesake, the city of Arenthia.

Origins and founding
The tension that started brewing in Tamriel after the founding of the Vilpesian Empire and the Crystal Concordate came to a boiling point in late 4E 206. The Concordate, intent on gaining dominance over the continent, launched a large offensive against the Empire from out of Valenwood, with the intention of conquering the Gold Coast and then moving east towards the Imperial City. However, the invasion force was soon met by fierce resistance from the Imperial Guard, and the offensive slowed to a crawl. The Concordate forces managed to capture Anvil in early 4E 207, but could not manage to progress further, as a more alarming matter arose to the east.

In order to relieve the pressure on the Gold Coast offensive, the Sixth Front of the Imperial Guard launched a counteroffensive on the Concordate, attacking Valenwood and the Khajiit kingdom of Anequina. Like the Concordate in the west, they conquered little terrain and their advance slowed to a halt quite soon, but they had at least managed to stop the invasion on their land.

In the months that passed, the Empire and the Concordate remained in a bloody stalemate, expending thousands of lives on both sides of the war but not winning any territory. The Concordate briefly attempted to alleviate the dire situation by launching a second offensive from Morrowind, but this initiative was quickly beat down by the Imperial Guard's Third Front.
