Taark Shanat

Taark Shanat (the Crusader) and his eight sons led a great exodus of dwarves out of Bhaerynden around -11000 DR to a new kingdom in the west. These emigrants eventually become known as shield dwarves and established the great empire of Shanatar beneath the lands of Amn, Tethyr, Calimshan and the Lake of Steam.

Background
Around -10800 DR, the Cloaker Wars broke out, in which Taark and his dwarves came up against the inhabitants of Rringlor Noroth. Taark slew four blue dragons in the Rift of Dhalnadar and the dwarves were victorious.

The skulls of the four blue dragons were brought together by a deity, probably Dumathoin, to form the Wyrmskull Throne, and the site was renamed Brightaxe Hall, founding the kingdom of Alatorin and this is what shield dwarves consider to mark the First Great Age of Shanatar.
