Nezznar was born in Menzoberranzan, into House Xorlarrin. The house was famous for its wizards, even giving the males status near to the females. From 1463 DR onward, House Xorlarrin possessed the Forge and much of Gauntlgrym, where they created fine weapons to export to Menzoberranzan. The entire house relocated to Q'Xorlarrin in Gauntlgrym in 1484 DR.
Nezznar's mission was to reforge the Flame Sword of Lolth in an attempt to win the favor of the goddess and aid in the Darkening to take the lands of the Silver Marches.
In 1486 DR, King Bruenor Battlehammer, leading an army of dwarves from the dwarven kingdoms of the Silver Marches, secured the upper reaches of Gauntlgrym. After pausing to fortify and begin repairs, the dwarves, with the help of the Harpells, descended into Q'Xorlarrin and retook it from the drow.
Nezznar escaped and swore vengeance on the dwarves, disappearing to seek a new Forge to recreate the Flame Sword. He hopes to follow in the footsteps of Tsabrak Xorlarrin, the archmage, who served as the conduit of Lolth in the spell known as the Darkening.
