The name Hirinsgate comes from the fact that the town sits on the only land crossing to the Isle of Hirin.
Hirinsgate is run by a Council elected from the ‘merchant’ class in the city. Though no longer the smugglers and crooks that inhabited the town during the war, they still take advantage of the relative freedom under which they can operate, and are not opposed to using their power in the Council to favour their business positions. Also on the Council is a representatives of each of the races present in Hirinsgate (Humans, Elves, Dwarves, Gnomes, Halflings and Orcs). The town pays and maintains its own city watch.
As the wealth and influence of Hirinsgate expanded, due to its regulations (or lack thereof) for trade, it has begun providing protection and governance for the entire region of Imdôr, though each town does still also maintain its own Council.
The sheltered and deep port at Hirinsgate also make it an ideal trading port, being able to cope with numerous ships in the bay between the mainland and the island.
