Dragon Age: Bad Company
The human settlement of Gwaren is built directly on top of a dwarven outpost by the same name. Prior to the First Blight, in a time when Ferelden was not yet a nation and was still carved up into barbarian tribes, the outpost served as a source of salt and a means by which the dwarves could reach the sea-lanes of the Amaranthine Ocean. Unwilling to come to the surface, the dwarves made an agreement with the local teyrn to build a port and relied on the humans to ferry goods between the ships and the underground outpost. This made Gwaren a prosperous place and extraordinarily wealthy for a time.
When, in the Divine Age, the dwarven kingdoms fell to the darkspawn and the Deep Roads were closed off, so too did the dwarves disappear from Gwaren. The human settlement, the envy of surrounding barbarian tribes, was assaulted and sacked, its wealth stolen.
The town remained, however, and despite its remote location continued to find value as a source of fish and timber. As the first settlement liberated by King Maric and Loghain during the Fereldan Rebellion, Gwaren was eventually granted to Loghain when he became teyrn in 9:11 Dragon.
