Descent to Undermountain (also known simply as Undermountain) is a role-playing game created and distributed by Interplay in 1997. It was developed by Chris Avellone, Scott Bennie, John Deiley, Robert Holloway, Steve Perrin.

"The stone belly of Undermountain below Waterdeep plays home to horrific monsters, dark magics, and unspeakable evils in DESCENT TO UNDERMOUNTAIN.

In this spell-ridden maze of dungeons and rips in the very fabric of reality lies the ultimate prize: The Sword of the Spider Queen, the Goddess Lolth. Stolen from her long ago, in a time when gods wrestled with the primal energies of creation, those who dared possess it were destroyed.

Based on an enhanced, SVGA version of the 3D engine from the immensely successful Descent game, all the horrors of the Abyss come to life with superior graphics that pay frightening homage to stunning detail. 360 direction movement makes no apologies for shameless attacks from behind. True to the AD&D system, you can develop your character from 6 different races, and create single as well as multi-class characters. Gain experience and discover magic items you'll need just to survive. In the end you'll trust no one but yourself. May the gods be with you."


In Eleint of 1370 DR, a hero was summoned by Khelben Arunsun at the behest of the Lords of Waterdeep to investigate the recent increase in kobold activity and thefts across Waterdeep. The Blackstaff handed the future hero two gold coins to pay for the passage to Undermountain through the Yawning Portal and sent him on his way.[1]

The hero uncovered the reason behind the kobolds' attacks: a drow High Priestess of Lolth, Azurna, was using the kobolds as part of her alliance to recover the ancient artifact that belonged to Lolth and bring ruin to Waterdeep. Continuing his investigation, the hero visited various locations within Undermountain and confronted Azurna's allies while collecting the pieces of a mysterious stone spider.[1]

Assembled Spider Statue of Lolth.

The Khelbenite confronted a Lolth-worshiping undead necromancer known as the Ghoulmaster in the Cassalanter family tomb on the Dungeon Level of Undermountain. He disbanded the operations of the sinister Shadow Thieves after their well-hidden return to Waterdeep under the leadership of the mysterious Xabash. He retrieved a lost heirloom that belonged to Maskar Wands from the Tomb of Ankh-Kephra, a Mulhorandi wizard. Later, he stormed an ancient dwarvish' prison taken over by the fiendish orc Horazak and his marauders. After that, he retrieved the Black Wand of Myrkul, aiding the Blackstaff's personal vendetta against the dead deity, and avenged the dwarves of the Clangeddin's Hearth, who had been slaughtered by Azurna's drow forces. The hero defeated the undead servants of Morik Stormhand, an old lich allied with the drow, as well as his fellow worshipers of Velsharoon.[1]

Eventually, the search for the spider pieces led to a confrontation with one of Halaster Blackcloak's apprentices, Ibbalar Thrul, who unleashed an army of spectators on the City of Splendors. Stopping the assault, the Khelbenite gained for himself the gratitude of both the city of Waterdeep as well as several noble families, such as Cassalanter, Wands, Phaulkon, Moonstar, and Ruldegost.

The final battle between the Khelbenite and the Avatar of Lolth.

Eventually, Lolth revealed the Khelbenite's search for the spider statue pieces to her priestess, Matron Azurna, and also gave her the location of the vault containing the Flame Sword of Lolth. The hero, who had gathered all the pieces of the statue, brought them to the Flame Sword's vault and re-assembled the statue. This gave the Spider Goddess access to the Prime Material plane via the Sword's divine powers. Taking the form of a huge female drider as her avatar, Lolth fought the Khelbenite. A fierce battle ensued, but the avatar was ultimately defeated. The hero destroyed the stone spider, banishing the avatar and making the Flame Sword disappear in an explosion of arcane magic. Waterdeep was safe once again, with the remains of Azurna's alliance destroyed or dispersed.[1]


The game partially derives its title from the use of the Descent 3D graphical engine. Undermountain allowed the player to interact with NPCs, monsters, and the general environment from a first-person perspective. The quest took place within the environs of the infamous super-dungeon of the Undermountain. Real-time combat would mix with puzzles to provide a variety of challenges throughout the vast dungeon.

The game was not the first to bring PC role-playing into a 3D environment, having been preceded by several titles such as Bethesda Softworks' Elder Scrolls Arena and Elder Scrolls Daggerfall along with Origin's Ultima Underworld series. It was, however, noted for being the first RPG to use a dedicated 3D engine such as that behind Descent to create a 3D world based on the Advanced Dungeons & Dragons license.

As the back of the box stated, the game included six different races that could take on single or multi-class professions with a variety of unique abilities such as thieves being able to climb walls. Over fifty different 3D monsters were in the game along with 160 magical items and forty different spells.


Players and critics alike have noted the unfinished feel of the game upon release. Cooperative multiplayer support, previously promised as a part of the title, was cut late in development because of severe technical issues to focus on the single player campaign.[2] The decision to use the Descent 1 engine was also cited as a design issue, as it required heavy rewrites to the code in order to support an RPG setting such as Undermountain.[3] Bugs, embarrassingly weak AI, the unappealing and shoddy nature of the graphics, and several other issues have attributed to a general consensus of the game as an example of a title that was pushed to release before it was ready.[4]

Further Reading[]


  1. After retrieval of the second stone spider piece, the Blackstaff states that Time of Troubles happened 10 years prior to the events of the game. Additionally, two documents in the game state that Halaster's Higharvestide happened the year prior to the game's events. Assuming Khelben was approximating the 10 years that passed since the Time of Troubles, Halaster's Higharvestide puts the events of the game in 1370 DR.
