Dwerren was the city of the Prime Dwarf , founded by The Blacksmith . It was a city of immense buildings, build with skill unrivaled for millennia. Dwerren was destroyed during the Second Age.
Dwerren was only ever populated by Prime Dwarves. No other races were allowed in to visit, much less to settle.
The Blacksmith ruled Dwerren through the caste system.
Set into the mountains of the far north, Dwerren relied on both high peaks and low temperatures to keep themselves safe. When war become a problem, walls were constructed at certain points, using the engineering skill of the Blacksmith.
