Nedeheim

Nedeheim (meaning "Down-home" in the Giant language ) was an ancient kingdom of stone giants, during the Time of Giants of the Dawn Age ( to ).

Geography
This kingdom was located north of Shanatar and south of the Cloud Peaks. It stood beneath Mount Dodild, part of the Giant's Run Mountains, within a high mountain cavern that extended to a depth of $1/2$ miles. Spread out through a series of lava tubes and caves.

History
Being of the kingdoms that made up the ancient empire of Ostoria, Nedeheim controlled the Giant's Run Mountains and carved great roads and stairs through its peaks, as well as tremendous halls beneath its peaks.

It was one of the giant kingdoms that warred with the ancient dragon kingdoms during the Dawn Age and was also one of the few fragment kingdoms that survived past Ostoria's fall. It eventually came into a conflict with the dwarves of High Shanatar, a conflict known as the Giant Wars, that listed sixty years. Finally falling in -5350 DR, having lost half its population and reduced to scattered clanholds, whose remaining inhabitants fled into the upper Underdark where they grew to be backwards and reclusive. Living in small clans that over the years fended themselves against countless threats, such as the people of Korolnor, Oryndoll, and Torglor.

In -160 DR, a cairn by the title of Dodkong came to to the site of the fallen kingdom with the crown of Obadai, the legendary crown of Faerûn's first stone giant, and gathered its stone giants clans together,  refounding the kingdom under the name of Cairnheim.

Over time this kingdom grew slowly, until by 1372 DR it had a sizeable population of 546 living within it. In addition, more than a dozen minor clanholds of stone giants and hill giants acknowledged the Dodkong as their ruler. Several large tribes of hobgoblins and orcs would rally around him if asked to do so. And nearby human communities offered him tribute. Around this time some communities within the Underdark began to fear that Cairnheim might be preparing themselves to expand beyond their borders.
