Thousands of years ago, nestled beneath the Hunterhorn Mountains, Kal-Sharok was once the capital of the dwarven empire. Its close proximity to Minrathous led to a strong bond with the Tevinter Imperium, contributing to the military and infrastructure of the burgeoning human nation.
The few dwarves living here are said to be extremely reclusive and reluctant to re-establish contact with most of the world, as well as being deeply embittered towards Orzammar for abandoning them during past Blights. The thaig was allegedly lost during the First Blight, though it was declared "rediscovered" by the Assembly of Orzammar in 9:31 Dragon despite the fact that the dwarves of Kal-Sharok had been trading with Tevinter, Orlais, and the Free Marches for quite some time. Thus far, the dwarves of Kal-Sharok have been slow to welcome outsiders, however, and scholars are only recently learning what these dwarves had to do in order to survive so many ages in isolation. Descriptions of these dwarves depict them as physically different than those of Orzammar. They are described as being pale, and possibly "tainted" in a way that is hard to define albeit some have made comparisons to Grey Wardens well into their Calling. These dwarves also don't share the relatively recent cultural influences of Orzammar's extended interactions with the surface. While the two thaigs do share the same base language, that of the Trade Tongue, Kal-Sharok has a regional dialect that draws more on an older manner of speech that is still less influenced by surfacers.
Kal-Sharok does not put much emphasis on castes, however they do still honour their Paragon ancestors... just not those of Orzammar. The practice of nominating Paragons changed from recognition of past deeds into recognition of promised deeds. Moreover, they do not recognize King Bhelen's rule, choosing to govern amongst themselves instead with that of Paragon Elect being the highest elected government office. The likenesses of Paragons are not rendered as giant statues in Kal-Sharok, as they are in Orzammar. Instead they are honoured posthumously with wall carvings that subtly span vast lengths of the Deep Roads.
The Dwarven Merchants' Guild, based out of Kirkwall, recently sent emissaries to Kal-Sharok but have heard no news from the delegation since. The Guild remains doubtful that they will find their emissaries alive.
