Thimdorlum Brasshand was the heir to Brazenthrone, the latest in a lineage of dwarves that had dominion over the mountain for thousands of years. The kingdom he inherited, however, was in its weakest state in generations. The production from the mines faltered, and with a dwindling populace, Brazenthrone was losing territory to hill-clans in the Snoutridge. Changes to the kingdom's structure were needed, which the High King recognized; however, he was poor at the subtleties of statecraft. When diplomacy was required, he tended to weaken his relationships with allies in the Kingdom of the Twelve Mountains through his bluntness and pride.
In haste to secure the region, Thimdorlum gave wide-sweeping powers to his soldiers who patrolled the central Snoutridge. While doing so stimied the advancing orc raiders, it caused further friction with the autonomous hill tribes. The situation got so poor that even his own clansmen, famous for their stubbornness, began to doubt Thimdorlum's leadership.
When a challenge came from Brufomura Blondebeard, he accepted, which lead to the Bending Of Brazenthrone and his untimely death. As he bore no children, this marked the end of his familial lineage.
