Upon its destruction in 1339 DR , it was the eighth house . The house was reformed as the eighth house in 1484 DR by Matron Mother Quenthel Baenre . Headquarters . Pre - 1339 DR . The Do ' Urden compound was located in the district of West Wall in Menzoberranzan . It was in fact built into the wall , with stalagmites forming the posts for the main gate . The two - level cave complex housed most of the house ' s residents . The first level featured a maze of tunnels , residences , training grounds , and a two - story chapel along the back wall . No stairs led to the upper level , restricting entrance only to nobles ( who had levitation abilities ) , who could enter through the chapel or front balcony . The ruling family lived within a set of suites on the upper level . The patron lived in a two - room suite , and the weapon master ' s three - room suite included private quarters , a training area , and the house ' s war room . Post - 1339 DR . After the house was destroyed in 1339 DR , the compound remained in ruins for more than a century . House Barrison Del ' Armgo and House Melarn used the ruins as training grounds for their troops until 1484 DR , Quenthel Baenre ordered Bregan D ' aerthe to clear the grounds in preparation for the house ' s restoration . History . Rise of House Do ' Urden . House Do ' Urden was ranked tenth house in the city until 1297 DR . In that year , the day on which Drizzt Do ' Urden was born to Matron Mother Malice Do ' Urden , House Do ' Urden attacked House DeVir , the fourth house . Using the power involved in Drizzt ' s birth , Malice and her priestesses were able to create a spell capable of defeating House DeVir . With this defeat House Do ' Urden became the ninth house . House Do ' Urden was favored by the ruling House Baenre , and therefore by Lolth , for many years . However , during a surface raid , Drizzt saved the life of an elven child ( Ellifain ) , and House Do ' Urden lost the favor of Lolth . Other houses discovered the house ' s fall from grace , and in 1328 DR House Hun ' ett began its covert attack on House Do ' Urden . To regain Lolth ' s favor , Malice sacrificed Zaknafein Do ' Urden , the father of Drizzt , instead of sacrificing Drizzt . This action was the " last straw " that led to Drizzt deserting Menzoberranzan and wandering the Underdark for a decade . During that decade , House Do ' Urden and House Hun ' ett continued to feud , neither having the favor of Lolth and each weakening the other but never to the other ' s victory . Destruction . In 1338 DR , House Hun ' ett hired Bregan D ' aerthe to launch a full - on frontal assault on House Do ' Urden . However , Malice entreated Jarlaxle , the band ' s leader , with a better offer and Bregan D ' aerthe turned on House Hun ' ett . House Do ' Urden won the day and became the eighth house of Menzoberranzan . However , due the weakened state of House Do ' Urden , Matron Yvonnel Baenre ordered SiNafay Hun ' ett , formerly the matron of House Hun ' ett , to become a priestess of House Do ' Urden under the name " Shi ' nayne Do ' Urden . " Matron Baenre also insisted that House Do ' Urden take care of the renegade Drizzt in order to reobtain Lolth ' s favor . Drizzt ' s siblings Briza and Dinin tracked down their rogue brother in the wilds of the Underdark but failed to bring him home or kill him . Malice took her biggest risk and summoned Zin - carla , a spirit - wraith , to hunt down Drizzt . To gain the power to do this , she sacrificed SiNafay at the altar and used the long - dead body of Zaknafein as zin - carla ' s host . However , during his trek to hunt down Drizzt , the mind and senses of Zaknafein returned enough for him to jump into an acid pit in order to save his son . Thus , Zin - carla failed and Drizzt was not captured ; Lolth ' s favor was lost forevermore . Briza killed her mother for her failure , becoming the new matron mother , but at that moment House Baenre moved in to destroy House Do ' Urden on behalf of Lolth . Vierna and Dinin were taken in by Bregan D ' aerthe and survived . Legacy of the Drow . In 1357 DR , Vierna tried to rebuild House Do ' Urden by attempting to kill Drizzt . With the help of Bregan D ' aerthe and Dinin ( whom she turned into a drider ) , she attacked Mithral Hall . During the attack , Bruenor Battlehammer slew Dinin , and Drizzt slew Vierna , leaving Drizzt as the last known surviving Do ' Urden . Reconstruction . By 1484 DR , soldiers and driders of House Melarn , as well as soldiers of House Barrison Del ' Armgo , were using the abandoned Do ' Urden compound as a training ground . That year , Bregan D ' aerthe soldiers , led by Jarlaxle ( named Captain of the Guard ) , were hired by House Baenre to clear the compound in preparation for the reconstruction and restoration of House Do ' Urden as part of Matron Mother Quenthel Baenre ' s plans to conquer the Silver Marches . To form the house membership , Quenthel selected a number of drow from other houses , starting with her own sister , Sos ' Umptu Baenre , to serve as temporary matron mother . Sos ' Umptu was quickly replaced by Dahlia Sin ' felle after her capture and corruption at the hands of Gromph Baenre and Methil El - Viddenvelp . Tiago Baenre was to serve as house weapon master after his return to Menzoberranzan . Tos ' un Armgo , recently returned from the surface with his daughter , was to serve as house patron . The house ' s garrison and foot soldiers were taken from Bregan D ' aerthe , supported by House Baenre . The house was given a position on the Ruling Council as the eighth house .
