Drizzt Do'urden was born in Menzoberranzan in 1297 DR as the third son to Matron Malice Do'Urden, the Matron Mother of House Do'Urden (a type of family akin to a Scottish clan) or Daermon N'a'shezbaernon. He was originally meant to be sacrificed to Lolth, the Demon Queen of Spiders, being the usual fate of the third living son of any Drow house, but was spared just minutes after his birth when the oldest Do'Urden brother, Nalfein, was assassinated by the second-oldest brother, Dinin, during a raid on a rival house.
Drizzt's father was Zaknafein, the renowned weapons master of House Do'Urden. Zaknafein secretly hated Drow society as a whole and it was he who taught Drizzt his formidable martial skills, but more importantly, reinforced Drizzt's innate moral code. Drizzt carries this code with him through the entire series.
During a raid against a group of surface elves, Drizzt found himself unable to participate in the slaughter with his fellow Drow. He pretended to kill an elven child but actually helped her to escape. When the deception was discovered Zaknafein was sacrificed in place of Drizzt to appease Lolth. Following a war against another House, Drizzt cursed his family and the evil drow ways, and escaped Menzoberranzan into the Underdark. It was also at this time that he acquired the statuette that allows him to summon the panther, Guenhwyvar, from the astral plane from a drow sorcerer after slaying him. Guenhwyvar has been by his side, saving Drizzt, and the friends he gains, numerous times, as they traveled across the realms and many planes. Hunted as a traitor to his race, he found that most other people he met treated him with hatred and disgust due to the legacy of the drow, leaving only the most open-minded and open-hearted to accept him.
One of these people was Belwar Dissengulp, a svirfneblin or deep gnome. Drizzt wandered the Underdark together with Belwar and a polymorphed pech nicknamed Clacker, but after fighting off the resurrected spirit-wraith of his father Zaknafein, Drizzt left Belwar and found his way to the surface. On the surface Drizzt met up with a blind human ranger named Montolio Debrouchee. When Montolio began teaching him the ways of the ranger Drizzt realized that, unknowingly, he had been following these principles his entire life. From this time on Drizzt made his patron goddess Mielikki, Faerūnian goddess of the forest and of rangers.
After the death of his mentor Drizzt traveled the realms in search of a new home, and eventually found himself in Icewind Dale where he met dwarven king Bruenor Battlehammer; Bruenor's adopted human daughter, Catti-brie; the barbarian Wulfgar (Bruenor's adopted human son); and Regis (Rumblebelly according to Bruenor), a loyal but unadventurous halfling. The group had many adventures together and would come to be known as the Companions of the Hall, when one such adventure led Drizzt and his friends south, to Mithral Hall (a city of the dwarves), where they currently reside.
Thrice in his life Drizzt has regressed into a bestial and instinctive state of mind, in which he was identified as the Hunter. The first time this happened was when Drizzt fled Menzoberranzan and was living in the wilds of the Underdark. The second was when he went back to his homeland to prevent harm from coming to his friends, as told in the book Starless Night. The third time was during the war with King Obould Many-Arrows when Drizzt thought Bruenor and his friends had been slain by Obould's horde of orcs.
He has become tangled in many workings of dark parties, from Lolth-worshiping drow to evil surface-dwellers, and even monsters from other planes. His greatest enemies have included Artemis Entreri, an assassin from Calimport (and also the main character in The Sellswords series), and Errtu the balor.
After nearly defeating Obould atop a mountainside using the sentient magical sword Khazid-Hea, Drizzt left with his elf companion Innovindil to visit the grave of Ellifain, the elven child he had spared many years ago. Upon his return to Mithral Hall, Drizzt is conflicted by the idea that the formerly war-like orcs are trying to live together with the dwarves in harmony. By the end of events in The Orc King (Transitions trilogy, book I) Drizzt and Bruenor join forces with Obould, who now wishes to live in peace with the other races, against a power-hungry half-orc half-ogre named Grguch who is challenging Obould's right to rulership of the orcs. Drizzt also fights against a curious polymorphed wizard who has joined the orcish ranks named "Jack the Gnome".
In his latest adventure, in "The Pirate King" (Transitions trilogy, book II), his views of the world begins to change as he begins to see more than just the black and white between good and evil. The changes of the orcs living in the Kingdom of Obould Many-Arrows have forced him to add more color to the gray areas between the black and white. This plagues him with doubts as he joins his old friend Captain Deudermont, a scourge to all pirates of the Sword Coast, in an attempt to bring down the leader of the Hosttower of Sorcery, a powerful lich providing help to the pirates of the Sword Coast.
