The War of Bend'r-Mahk increased the territory that is considered Skyrim considerably, allowing the Nordic counts to swallow up many miles of eastern High Rock and Hammerfell. Resistance by the Bretons and the Redguards is feeble in the cities of Jehenna and Elinhir, and more active in the border zones of the countryside. The city-state of Dragonstar continues to be divided into western and eastern sections, walled off from one another, each with its own government, and each with an atmosphere of mistrust and fear. There are few days without an act of terror from one resistance group or another, though, so far little territory has changed hands since the days of the Imperial Simulacrum.
Solitude, always one of the richest and most influential counties in Skyrim, has grown ever more powerful, controlling much of the northern coastline following King Thian's alliance by marriage with Macalla, the Queen of Dawnstar. It has sought to expand its influence further by annexing several former Imperial fiefs, such as the island of Roscrea, ruled directly by the Emperor since Uriel V conquered it in the 271st year. It has begun sponsoring exploratory missions even farther from the mainland into the misty waters of the Sea of Ghosts.
Winterhold, Solitude's ancient rival, has also experienced a renaissance of power and influence. Refugees from Morrowind, far from burdening the eastern city, have brought with them new ideas, enriching her culture and stimulating its old mercantile spirit. Scholars from all over Tamriel have descended on the county since it became home to the Ysmir Collective, a library rescued from destruction in the east, and the cornerstone of academic life at the College of Winterhold.
Hrothgar and Whiterun have not been as fortunate as their coastal northern cousins. A dynastic feud, attacks by H?rme bandits and frost trolls, and a series of annihilating winters of alternating floods, droughts, and fires has crippled the area that was once considered the Imperial City of Skyrim. The population blamed and then curiously exalted the leader of the local witches' coven, Jsashe, a self-proclaimed priestess of Lorkhan. The Witch-Queen of Whiterun, as she is called, now wields effective control of the county, though her magic has not brought it prosperity as of yet.
