In fact, the first order for Vsevolod, Grand Duke of Kiev is to re-assert his undisputed control all the way down to the capital to the south.
With the royal court in Kiev in such disarray, it would seem that any immediate military campaigns should be launched from around the trade capital of Novgorod. Positioned just off the eastern end of the Baltic Sea, Novgorod is presently one of the most important trade hubs in the region, while in Kiev, disputes over succession have destroyed any sense of organisation or unity. Kiev may actually be the royal capital of this Kingdom, and the site where the Rus' embraced Christianity, but it is far to the north that the true power of the realm currently lies. The Rus' are a people divided, though that is hardly a character judgement for the folk who live in the largest single kingdom in Europe.
