I kinda explained the D'Hara thing a long time ago...
But first let me say that the original Shadovar rebellion was performed by Mathias Ridder, who enlisted the help of Yoruk Bronzeweasel. Apparently Yoruk got shafted immediately after the rebellion was successful. lol @ Mathias for stabbing his friends in the back.
A few posts back someone explained the situation with Madina's capital.
As for D'Hara, it went through several adjustments since the original Shadovar rebellion. Katayanna seceded to form D'Hara. Later Cenarious rebelled and became the Dragon King in 2008. In 2010 or sometime recently Cenarious disappeared and now there's a new guy. Ask D'Harans for details.
