Gormagog

Gormagog, the forbidding bastion of Mount Gora, is a fortress-city on the fringes of Tyrrus ruled and populated almost entirely by Troglodytes. The city sits overlooking a narrow mountain passage within the uncivilised Ishkari Mountains, and is the only major settlement in the area.
The original fortress of Gormagog was built long ago, likely by the Rune Kingdom, but after their collapse it came to be occupied by trolls and ogres, who were smart enough to realise the importance of the location. The passage Gormagog overlooks is highly important, and profitable, as it is the only way of getting from Tyrrus to Izir by land, without going through the heavily-taxed routes through Whytehold. The passage can also take you from Tyrrus to Kaldinen, bypassing the Hinterlands and the Great Northern Wall.
The route is most commonly used by opportunist traders who want to avoid paying the extortionate taxes charged by Whytehold, or traders whose nations are at war with Whytehold. Gormagog still demands a tax, but it is far lesser. Unless the troglodytes decide, on a whim, to eat the traders caravan. Before the Worldshaking of 20.20, this route was sometimes used by Izirian cartels, who smuggled goods into and out of Tyrrus. The Kingdom of Whytehold itself uses this route to send supplies to their northern outpost, the Frozen Crown.
Gormagog is in a near-constant state of civil unrest. Conflicts over who should lead the nation are common, and there are often disagreements between the different varieties of troglodyte present in the city. The ogres are the strongest, but the trolls are the most numerous, and the harpies have the advantage of flight, while the Hags serve their own means and manipulate matters from the background.
