Kingdom of Gardadth
Source: Dwarves of Golarion, pg(s). 8

The Kingdom of Gardadth was the first of the five dwarven kingdoms established in Five Kings Mountains. It was founded by Baron-mayor of Highhelm, Gardrick I in 1557 AR. The kingdom collapsed in 2497 AR, after the invasion of orcs and the five-year-siege of Highhelm, but Highhelm did not fall and remained to defend the dwarves and humans in Five Kings Mountains area during the nearly 700 years long Wild Era.1
