House Oblodra House Oblodra was a deceased drow house of Menzoberranzan . Base . House Oblodra ' s compound was located in the district of Duthcloim ( often referred to as Manyfolk ) , where it clung to a cliff face between the two " fingers " of the Clawrift . Its compound was small but protected on three sides by the Clawrift and guarded by soldiers on the other side . Most of the Oblodrans ' slaves were kobold s kept in pens and tunnels in the Clawrift . Although the Oblodrans claimed to have only 600 kobolds , the Clawrift was capable of holding ten of thousands more , and many houses suspected they were lying . Although the diamond - shaped compound was small , it was quite spacious relative to the number of inhabitants . Even lower - ranked drow had private chambers . Activities . House Oblodra was gifted in the rare art of psionics and its members were known for their fanaticism to psionics . They were considered reckless and insane by the rest of the city . It was rumored that the house sent its daughters away to train with ( and even breed with ) illithid s . The House of very secretive . House Oblodra ' s garrison was always smaller than that of other , lesser houses , in part because of soldier ' s participation in a dangerous duelling game called " Khaless " . Participants levitated in a magically darkened and silenced area over the Clawrift ; the first drow to leave the area ( either by giving up or falling ) lost . Many participants failed to adequately time their levitation and fell to their deaths . Winners were given various luxuries ; losing survivors were forced to clean kobold pens . Oftentimes , however , there were no survivors . House Oblodra backed the Brown Mushroom Mercantile Company . History . In 568 DR , illithids from Phanlinksal attempted to invade Menzoberranzan . The Menzoberranyr defeated the invading illithids at the Cavern of Severed Tentacles and fed the dead illithids to vampiric illithid s that House Oblodra kept as pets as the surviving captives watched . House Oblodra used its wild talents to ascend to the third house of Menzoberranzan by 1297 DR , obliterating many of the houses that stood in their way . Despite having smaller forces than houses behind them , matron mother K ' yorl Odran ' s wiliness in politics , as well as her skill in psionics , kept the house secure in its position . For much of history , the illithid Sept of Ill ' Ghact desired to destroy House Oblodra . However , when Methil El - Viddenvelp discovered in the 1340s DR that illithid tadpoles could be implanted in the drow psions of the house , the sept changed their opinions and began seeking the most powerful members of the house to use as hosts . A number of illithids that were notable in later years were spawned from Oblodran nobles during this year , including Galgast and During the Time of Troubles ( 1358 DR ) , when magic was unpredictable , House Oblodra briefly became the most powerful house in the city . They attacked House Faen Tlabbar and killed K ' yorl ' s rival , Ghenni ' tiroth Tlabbar . K ' yorl then gathered the Ruling Council in order to place her claim as ruler of the city . However , in the meantime , Lolth made a deal with the balor Errtu , who sent demons to aid House Baenre , led by Yvonnel Baenre , and attack House Oblodra . Yvonnel summoned a tentacle from the Abyss to sweep the entire house into the Clawrift . K ' yorl remained alive , but Yvonnel banished her into the Abyss to be tortured for eternity by Errtu . One of the other few survivors , Kimmuriel Oblodra , was taken in by Bregan D ' aerthe and later became one of the band ' s leaders . After the fall of House Oblodra , undead Oblodran priestesses were believed to haunt the Clawrift as witchlin s , stalking the kobolds that lived in the Clawrift . In the late fifteenth century , the priestess Minolin Fey - Branche contemplated releasing K ' yorl from the Abyss in hopes of House Baenre being destroyed . However , she feared Lolth ' s wrath if she did so .
