Drizzt was born as the third son to Malice Do'Urden (the then Matron Mother of House Do'Urden) and was originally meant to be sacrificed to Lolth (the usual fate of the third son of any house), but was spared minutes before he was born, as his oldest brother had been assassinated by his second-oldest brother, Dinin, and thus making him the second living son and not the third. His father, Zaknafein, was the renowned Weapons Master of House Do'Urden and secretly hated drow society as a whole. He taught Drizzt the way of the blade, and more importantly, taught him a moral code.
Drizzt left Menzoberranzan in search of a better life, and eventually found his way to the surface after time alone in the wilds of the Underdark and a sojourn with the Deep Gnomes. Most people he met treated him with hatred and disgust, leaving only the most open-minded and open-hearted people to accept him. One of these people was Montolio Debrouchee (Mooshie).
