Editing Mind Flayer Colony

{{SpoilerWarning}}
The Mind Flayer Colony is a [[List of Locations|location]] under the [[Moonrise Towers Prison]] in the [[Shadow-Cursed Lands]] in [[Act Two]]. This area is accessed by jumping down into a tower after the initial [[Ketheric Thorm]] fight on the [[Moonrise Towers Rooftop]].

[[File:MindFlayerColonyMap.png|right|thumb|Map of the Mind Flayer Colony]]

When arriving from the Moonrise Towers Rooftop, destroy the membrane and move forward. The colony has many intellect devourers running around, which will only become hostile if a fight breaks out nearby.

== Points of interest ==

=== Morgue ===

The morgue is run by [[Chop]], a strange bugbear who butchers humanoids to create new [[Intellect Devourer|intellect devourers]]. 

[[Us]] can be found imprisoned here if it was not destroyed on the [[Nautiloid]]. After talking to Us, you can convince Chop to give you a [[Morgue Cage Key]] with a successful{{Ability check|Persuasion|14}}, {{Ability check|Intimidation|18}}, or Illithid Wisdom. If freed, Us will reward the player with the item [[Summon Us]].

If the player threatens to kill Chop, he will respond as though he wants the player to kill him. Despite this, attacking him will still make Chop and the surrounding intellect devourers (except for Us) hostile. Nonetheless, Chop will comment that he is "free at last" as he is killed. The intellect devourers outside of the morgue will remain neutral.

=== Necrotic laboratory ===
Balthazar's [[Necrotic Laboratory]] can be found in the south-east of the map, at {{Coords|715|-49}}. When you enter the area, a battle with a large number of undead will commence, including: 1× Death Shepherd, 4× Winged Horror, 4× Greater Zombie, and 6× Zombie.

Further southeast is a [[Brain Mapping Puzzle|brain mapping puzzle]], consisting of four mental faculties (Emotion, Speech, Memory, and Reason). To solve this puzzle, you must connect each to its identical matching faculty on the far side of the puzzle by selecting intervening nodes. Successfully solving the puzzle will grant the [[Inspiration|Inspirational Event]] '''Brain Blast!''' ([[Sage]]) and access to the [[Blade of Oppressed Souls]] and the [[Waking Mind]]. Beside the Waking Mind is a skeleton{{Coords|750|-138}} with the [[Circlet of Mental Anguish]] and [[Braindrain Gloves]].

The Mind-Archive Interface at {{Coords|699|-117}} allows you to talk to the brain jars found scattered across the area.
* The [[Waking Mind]] found behind the brain mapping puzzle can grant a permanent buff: [[Githzerai Mind Barrier]].
* The [[True Mind]], [[Willing Mind]], [[Butchered Mind]], [[Closed Mind]] and [[Fresh Mind]] brain jars elsewhere in the Colony, as well as the [[Dark Mind]] and [[Slave Mind]] brain jars from the [[Nautiloid]], will only give dialogue.

[[Mol's Eyepatch]] and a [[Prayer for Forgiveness|note]] shedding some light on The Dark Urge can be found on a table near the mind-archive interface.

=== Tadpoling centre ===

[[Zevlor]] can be found here for the [[Find Zevlor]] quest. There is a long room filled with pods; some contain non-hostile humanoid characters, including Zevlor, while others contain [[mind flayers]]. A Neural Apparatus at {{Coords|689|17}} gives the player a choice between purging all of the pods (illithid and humanoid alike) and opening them all. 

If the player chooses to purge the pods, Zevlor will die; if they open the pods, they must fight several mind flayers and intellect devourers (though the newly-freed NPCs will fight alongside the player, providing significant aid.)

Zevlor and the other survivors can potentially turn hostile if they are damaged by the player, including via spell AOE effects such as Cloud of Daggers or Flame Wall.


In the next area, [[Mizora]] is stuck in a pod. The player may free her in order to advance [[The Blade of Frontiers]], Wyll's companion quest.

The left control is "annihilate," the right one is "unleash", each requires {{Ability check|Arcana|10}}. If Mizora is freed and Wyll is in the party, Mizora may be persuaded (DC 14) for a reward; this results in her giving Wyll the [[Infernal Rapier]], a unique Very Rare rapier. '''Important''': Killing Mizora via the "annihilate" button results in Wyll dying as well.

Interacting with the brine pool near Mizora ({{Ability check|Perception|16}}) yields a [[Mind Flayer Parasite Specimen]].

=== Barracks ===
In the north-eastern corner of the colony are the barracks, where the party will meet [[Kressa Bonedaughter]] and her Skull Lashers. After brief dialogue, you may fight Kressa or convince her to stand down with a successful {{Ability check|Deception|21}}. If friendly, Kressa can be persuaded ({{Ability check|Persuasion|18}}) to grant her blessing, {{Condition inline|Myrkul's Gift}}, to each party member that speaks to her. 

{{SpoilerDurge|Kressa will recognise [[The Dark Urge]], if present and undisguised, and recall the time spent under her ''care'' in the colony. This conversation inevitably leads to combat.}}

In the chambers are also several notes in the area that can shed light on The Dark Urge.

== Advance to Ketheric Thorm ==
{{main|Defeat Ketheric Thorm}}
[[File:Rick-van-den-berg-rick-vdberg-larian-bg3-act2-mindflayercolony-01.webp|right|400px]]To the east is the big showdown with [[Ketheric Thorm]]. Before descending down the lift use the Restoration Pod to the right of the lift to receive the benefits of a [[Long Rest]].

A cutscene will then play, wherein the player will see [[Ketheric Thorm]], [[Enver Gortash|Gortash]] and [[Orin]], learn of their plans, and meet [[the Netherbrain]], thus discovering the true identity of the [[Absolute]]. If [[Gale]] is in the party, the player will have the option to allow him to explode the Netherese Orb; this will kill the Netherbrain, all three Chosen, and your party, resulting in a very early endgame and the credits rolling. If this action is not taken and the party remains unexploded, this cutscene continues with the Elder Brain infecting [[Ulder Ravengard|Duke Ravengard]] with a Tadpole, before the Chosen of the [[Dead Three]] unleash their assault on Baldur's Gate.

=== Fight with Ketheric ===
If the player passes multiple Persuasion and/or Intimidation checks both atop Moonrise Towers and in the Mind Flayer Colony, asking him to repent, the first half of his fight in the Mind Flayer Colony will be skipped as Ketheric gives himself to Myrkul. 

Otherwise, when the second fight with Ketheric starts, Ketheric will begin by calling on [[Myrkul]] for aid. Ketheric remains invulnerable so long as he has the [[Dame Aylin|Nightsong]] captured. The player's initial goal is to free Nightsong with the Help action, as she is trapped inside a soul cage by Ketheric. 

See [[Ketheric Thorm/Combat]] for details of this battle. 

After the battle will be a series of cutscenes. The player will be teleported back to [[Moonrise Towers]] ground floor, where they can speak with some of the characters met in the [[Shadow-Cursed Lands]] before heading west to Baldur's Gate. This is the end of [[Act Two]].
