Gauntlgrym

Gauntlgrym is a subterranean dwarven city beneath Mount Hotenow nestled amid the Neverwinter Wood.

The party visits here as they head north, initially to collect some warm clothing.

As they approach the city, Hammerfeet relays the lore he remembers of the place-  In ages past the subterranean city was capital of the Delzoun empire. it's cavernous halls, some large enough to contain entire surface villages, were carved with unerring precision and their ceilings soared scores of feet overhead. Their towering statues of dwarven gods and heroes stood vigil over chambers and thoroughfares, the least of which was wide enough to march 50 dwarves standing abreast. The mines produced endless tides of iron, silver, gold, and mythril and booming trade brought goods and wealth to the city from across Faerûn. But it was a great forge that was the burning heart and true treasure of the city. Deep beneath the settled levels of Gauntlgrym, dwarven crafting and elven magic bound a slumbering primordial Maegera, a being of fire and destruction, harnessing incredible power to heat the forge. Hammerfeet mentions the place had been taken by Drow, then taken back by Bruenor Battlehammer who is currently reigning here.

The party encounters several regions of Gauntlgrym, including the Iron Tabernacle, the Vault of Kings, and the Great Forge.
