Gruordock started as a make-shift mine, supplying gemstones to Thadir.
In the First Epoch, Gruordock was a hold of the Damizdaluk. When the white dragon Amaglothorn unleashed her wrath upon Inzurakthol, Gruordock was entombed in ice.
In 851, a decade after the ending of Amaglothorns Breath, a band of bugbears and trolls moved into the ruin. They would sometimes dig a dwarf out of the ice, thawing it and then feasting on the long dead cadaver. A century later, the place was captured by a Grimlock army led by undead illithid.
Gruordock is positioned over a series of waterfalls, which along with many other waterways, drain into Inderch. From the battlements of this keep, one can see far out into the Sea of Mourning. During the hotter months, Inzurakthol's melting snow and glaciers flood Gruordock's lower levels.
In 1576, the Cult of Worms sent an expedition into the place to find a powerful dwarven priest that in life had served Rioch Tetrax. They found him buried in ice, frozen to death for more than seven centuries. They promised to raise him, so that he could get revenge on those that had desecrated Gruordock and ravaged the bodies of frozen dwarves.
Today, a wight-king, a Taln'nazân Monarch holds sway over Gruordock.
