Clan Icehammer The Time of Troubles & Era of Upheaval Inspired By Ed Greenwood

Clan Icehammer was a clan of dwarves that hailed from Icespire Peak in the Sword Mountains during the 12th century DR. The dwarves of Clan Icehammer were avid and successful miners.

They dwelled within the stronghold of Icespire Hold on the mountain's surface, they constructed a mighty underground fortress of catacombs within. The eponymous weapon known as the Icehammer was a dwarven throwing hammer long-associated with the clan with which it shared its name.

Over time, they developed immense enmity towards frost giants and goblins that also dwelled on Icespire Peak. This hatred came to a head early in the 1200 DR's and the Frost Giants attacked the stronghold, some even say that a force of unknown creatures attacked from deep below the stronghold in the catacombs below through an uncovered passage that was supposed to lead into the Underdark, "this is all rumors and speculation though".
