Mind Flayer Colony

The Mind Flayer Colony is a location you can find from the Oubliette under the Moonrise Towers Prison in the Shadow-Cursed Lands in Chapter Two. You can access this area once you have faced Ketheric Thorm for the first time on the Moonrise Towers Rooftop.

If you arrive here from the Moonrise Towers Rooftop, destroy the membrane and move forward. There will lots of Intellect Devourers running around the colony. They are not hostile.

There are a number of sub areas to the colony:

1. Morgue - You'll find Us here if they weren't destroyed on the Nautiloid. You can free Us to get the item Summon Us.You'll also meet Chop here.
2. Necrotic Laboratory - In the South East (X:715 Y:-49). This area has lots of undead and a brain mapping problem to get access to the Blade of Oppressed Souls and a wall decoration talking about the Mind Flayer Grand Scheme. On a skeleton here you will find the Circlet of Mental Anguish and Braindrain Gloves. Near the Blade of Oppressed Souls you will find a brain jar called Waking Mind that you need to insert into the nearby Mind-Archive Interface (X:699, Y:-117) and talk to the Slack-Skinned Head to gain a permanent buff - Githzerai Mind Barrier if you purge the mind. The nearby True Mind and Willing Mind brain jars do nothing.
3. Tadpoling Centre - You'll find Zevlor here. If you want to free him you will have a fight with some of the mind flayers and intellect devourers. In the next area you can find Mizora stuck in a pod. Free her if you want to advance Wyll's quest (The Blade of Frontiers). If you decide to free her then persuade her (DC 14) for a reward to get Infernal Rapier.
4. Barracks - Here you will meet Kressa Bonedaughter and her crew. Fight them or deceive them. There is nothing else of interest in the barracks.

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 get a free Long Rest.

You will watch a cutscene between Ketheric Thorm, Gortash and Orin and meet the Elder Brain and learn of their plans and the fact the Elder Brain is the Absolute. If you have Gale with you, you have the option to let him go nuclear and kill the Elder Brain. You will watch the Elder Brain infect Duke Ravenguard with a Tadpole, before the three unleash the assault on Baldur's Gate.

Fight with Ketheric

Time for the next fight with Ketheric. He'll call on his god for help and the fight will start. Remember that Ketheric remains invulnerable as long as he has the Nightsong captured. Your initial goal is to free Nightsong with the Help action, as she is trapped inside a soul cage by Ketheric. After the battle you will get a series of cutscenes and then Chapter Two will be pretty much finished.
