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.

Advance to Ketheric Thorm

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 Netherbrain 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 Ravengard 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. you'll teleport back to Moonrise Towers ground floor where you can talk to some of the people you have met in the Shadow-Cursed Lands before you head west to Baldur's Gate. Chapter Two will be pretty much finished.
