Underdark

The Underdark is a massive underground complex of tunnels and caverns, sprawling beneath the surface of Faerûn. 
== Description ==
It is home to many subterranean races, including but not limited to, the Svirfneblin, the Duergar, and the Drow. Within the Underdark lie many wonders as well as cities, such as Menzoberranzan, possibly the most infamous and largest of the Drow City-States and is where both Drizzt Do'Urden and Viconia De'Vir hail from. The Underdark is infamous for being deadly to both outsiders and those who consider it their home in no small part due to being infested with monsters like Aboleths, Illithids, Beholders, Hook Horrors, and Umberhulks, as well as natural disasters like cave-ins.
== Plot recap and entry into the Underdark ==
Gorion's Ward is in pursuit of Irenicus and Bodhi. Clues obtained from Saemon Havarian, statements from Irenicus, as well as the First Journal of Jon Irenicus and Second Journal of Jon Irenicus all point to the underdark as the location of their quarry.
The party eventually transitions to the underdark, from either the portal in the Spellhold Basement or by way of the shaft and Magical Rope in the Underwater City.
Upon the transition, a cut scene plays exhibiting a meeting between Jon and a matron mother of Lolth in Ust Natha. Some insight is gleaned from this in that Irenicus has worked out some kind of alliance with the dark elves in the city. 
The party then arrives in the underdark, and shortly after another cutscene movie plays for the beginning of chapter 5, introducing the chapter's plot and a sinister description of the underdark.
Gameplay begins afterwards, and it is up to the party to explore and investigate this strange place and track down Irenicus. For a first-time player, the game does not specify exactly what to do, where to go, or any initial must do actions.

==Mod content==
===Tactical Mod content===
The Sword Coast Stratagems Mod makes various changes to Underdark creatures and assigns new AI scripts as part of various optional components selected during installation. The Balor, Mind Flayers, Beholders, Adalon the Silver Dragon, Kuo-toans, drow warriors and spell casting drow are all potentially improved. The game difficulty setting will adjust the numbers and type of creatures found as determined by the SCS Spawn scripts. Aside from individual creature improvements, there will also be potentially more enemies included in the Drow ambush, drow war party and Kuo-Toan bridge guardian areas, as well as more Umber Hulks and Mind flayers. The harder the difficulty, the more the challenge.
===Quest Mod content===
Afaaq the Djinni Companion Mod has significant new quest content added for the Underdark and Ust Natha. Afaaq, the party's djinni, will have much insight and banter here.
CoM Encounters mod adds a drow war party encounter with a Matron Mother leading them. This will take place at the landing zone as the player first enters the Underdark. This mod is compatible with the SCS mod's AI scripts and the Spell Revisions changes if those are also installed. On higher difficulty levels, this encounter is most likely more difficult than anything taking place in the previous areas in Chapter 4. There is little time to prepare for it, so beware. 
Eilistraee's Song Mod begins in the Underdark and adds a new adventure and quests that span beyond chapter 5.
The Quest Pack Mod adds a new area and a Lich to the Western Tunnels. Extra content is also added for A Mage's Proposal quest.
Adalon's Blood Mod introduces new choices and content for the Underdark and Ust Natha.
