Menzoberranzan

Menzoberranzan, or the City of Spiders, is a gigantic underground Drow city-state. It is located in the Upper Northdark, about two miles below the Surbrin Vale, between the Moonwood and the Frost Hills. Menzoberranzan is possibly the most popular drow city in Faerûn. It was the home of Drizzt Do'Urden, and many of his adventures deal with the political intrigue and characters of the city.

The city has different factions, or houses, all of which vie for power. It is currently under the indirect rule of House Baenre which is governed by Triel, daughter of Yvonnel Baenre or Old Matron Baenre. Recently there has been a revolt in Menzoberranzan that was put down. At this point what this revolt will do to the current power structure of the city is unknown. But the loss of one of its trade partners, another Drow city, will most likely cause a huge shift in power.

Overview
The city has 32,000 inhabitants – one third drow and the rest humanoid slaves. The city trades poisons, tasty mushrooms, riding lizards, spell scrolls, wine, and water. The worship of Lolth is prevalent, and the city has the clerical academy Arach-Tinilith, a spidershaped building where priestesses are trained. One of the branches of the city's triune academies of Tier Brieche, Arach-Tinilith is neighboured by the warrior school Melee Magthere, and Sorcerer tower where arcane spellcasters are sent to study. These academies are the quarters of some of the most powerful spellcasters, clerics, and fighters respectively, and the title of master of an academy is coveted, since being the master of Sorcere or Melee Magthere is as high as the power ladder goes for some houseless drow or even noble males.

Menzoberranzan was founded by a priestess of Lolth named Menzoberra the Kinless. It is ruled by a council of matrons from the eight greatest noble houses; the most powerful House in the city is House Baenre, until recently led by Matron Yvonnel Baenre – a drow cleric who was the single most powerful political figure in Menzoberranzan for a few thousand years. She has been succeeded by her daughter Triel. A separate council of mages deals with affairs of the arcane – but as its members are all male, it is wholly within the grip of the matrons.

History
Menzoberra the Kinless, a powerful priestess of Lolth, founded the city that bears her name in −3917 DR. By the wishes of Lady Lolth, she led seven drow families into the Northdark from the southerly drow holdings of Great Bhaerynden. The drow families, having no immediate external enemy, fell to attacking and undermining one another, as was drow nature, to the greater glory of their evil goddess, who so loved chaos. Only fifty years after the city's founding, in −3864 DR, a great and terrible battle between the two most powerful Houses, House Nasadra and House S'sril, occurred. This battle led to the exile of House Nasadra (which later founded the city of Ched Nasad, and was the First House until the city's recent destruction) and to the rise of House Baenre as the First House of Menzoberranzan.

The city's internal machinations have continued unabated for millennia. The Houses that grow weak are destroyed, and newer Houses rise up to find Lolth's favor. The full history of each House would constitute a nearly endless logbook of treachery, spite, and unceasing ambition. Within the last century, this pattern seems to have accelerated. House Do'Urden ascended from the Tenth House to the Ninth House by destroying the Fourth House, House DeVir. It then ascended to the Eighth House with the much-needed help of Jarlaxle's mercenary band Bregan D'aerthe by destroying the Fifth House, House Hun'ett. House Do'Urden lost the favor of Lolth, however, when Matron Malice Do'Urden turned Zaknafein Do'Urden into a spirit-wraith by using Lolth's dread Zin-Carla ritual and failed to kill Drizzt Do'Urden with him. This resulted in House Baenre utterly destroying House Do'Urden.

In 1359 DR, during the Time of Troubles, House Oblodra, the Third House, aspired to be the First House of Menzoberranzan. Menzoberranzan was caught in a magic-dead zone, so magic currently did not work there. House Oblodra, however, was gifted in the rare art of psionics and seized upon this opportunity to strike at the other Houses. The matron of House Oblodra nearly reached her goal, but an avatar of Lolth answered Matron Baenre's pleas for help and came to Menzoberranzan after the Time of Troubles had ended. (The drow thought that she herself had restored all magic, but that is not true.) Although she loved chaos, she did not wish to see a House that did not whisper prayer to her to rule the city. Forseeing her temporary loss of power due to the Time of Troubles, Lolth had asked the demon Errtu to protect her worshippers, should she herself fail to do it. In return, Lolth relinquished the hundred-year ban from the Material Plane that had been placed on Errtu when Drizzt Do'Urden had killed him and gave Wulfgar over to Errtu as a prisoner. She then opened a portal for Errtu and his host of demons to lay siege to House Oblodra. By the time the Time of Troubles had passed, Lolth was restored to full power and single-handedly crushed House Oblodra, the remains of their stronghold being pushed into a deep chasm known as the Clawrift, and Matron Oblodra's spirit went to Errtu for eternal torment. Thus the ranks of the ruling Houses changed once again. All this she said was done for her greatest high priestess (although it was really done for herself), the two thousand-year-old Matron Baenre. All Houses in the city witnessed this great miracle and knew that House Baenre was the most favored House of the goddess.
