Hammerdeep

"Here in these ancient halls the sound of hammers rang day and night, and the fires burned so hot, even the gods shied away from it"
-Lethae Margon
Hammerdeep, known also as Nulzad-Dol (Warhammer-Mountain), is a forge city in eastern Kondrakis. It is the second largest city on the continent, after Arrowmight. It is located deep within Mount Khrozad, an active stratovolcano. 
The city is known for its smithing and metalworks. The city's location in the magma chamber of a volcano gives it a natural source of immense heat, allowing its forgers to easily smith weapons and armor of immaculate quality. As a result it has been conquered and re-conquered multiple times throughout its history. It is currently ruled over by the Red-Gold Empire, having been conquered from the House of Chalgrae at its fall at the beginning of the 12th era. 
The city is incredibly ancient, and no mortal soul knows when it was founded. The only true fact I can divine about it is that it's founder, Lethae Margon the Smith, achieved godhood in the Age of Myth, meaning that Hammerdeep is among the oldest cities in the world.
