Tarquazhan

Tarquazhan is the capital of Tarq, the nation of Dwarves. It was built on the site of the second Ytarran capital, to which they relocated after the first Ytarran capital (on what are now the Illud Highlands) was cut off by the Thrashing Sea.
It is very likely the site of the tomb of Y'Solas Turi, which contains one of the three Ytarran Creation Matrices.
