Forum:I wish to know more about Dambrath

I am curious about a particular part of Faerun called Dambrath. Here is what I know about it:

History:

211 DR: Four tribes of barbarians called the Arkaium fleeing the legions of Unther and Mulhorand settle along the coast of the Bay of Dancing Dolphins.

545 DR: King Reinhar I officaly founds the nation of Dambrath and leads an invasion of Luiren, conquering it’s halfling inhabitants.

802 DR: Miners in the Gnollwatch mountains make first contact with the drow city of T’lindhet.

831 DR: The drow invade and take control of Dambrath.

By 1358 DR Dambrath contains the cities of Cathyr, Herath, Maarlith, Purl and T’lindhet of the Underdark region. It is ruled by a group of elves known as the Crinti a product of human drow interbreeding.

Significant Geographical features include: The Bay of Dancing Dolphins at the centre of Dambrath, named for the Dolphins synchronized swimming in the bay.

Gnollwatch Mountains and the “Hills Of The Dead Kings” that form the northern border of Dambrath.

The river Ammath to the east. The river Dambron in the west flows form the Gnollwatch mountains.

Rethild (The Great Swamp) lies between the western border of Dambrath and the Eastern Wall of Halruaa. It is home to ruins and various monsters such as shambling mounds, tendriculoses and lizardfolk as well as a particularly clever dragoon named Valraxaxath.

The Kingdom of Dambrath is bordered on it’s east by Luiren. On it’s North by the Shaar. On it’s west by Halruaa. On it’s south by the Great Sea.

Religious:

The worshiped deities are: Loviatar, Lolth, Malar and Eilistraee.

I would like to know more about the region, important people, details of cities & towns, religions etc between the dates 200 DR and 900 DR in particular. Any information or books suggested or links you could provide would be most appreciated. Thankyou. :)
