Location from baldurs-gate-3 by Larian Studios
The final dungeon of Baldur's Gate 3 — the Elder Brain assaults the city's seat of government while the Netherstones converge and the fate of every sapient creature on the Sword Coast hangs on one confrontation.
High Hall is Baldur's Gate's governmental heart, and by the finale it's a war zone. The Elder Brain, now freed and empowered by the Netherstones, squats atop the building like a cathedral of flesh, its tentacles punching through walls and converting citizens into Mind Flayer thralls in real time. The approach is a gauntlet — nautiloid wreckage, brain-jacked soldiers, and transformed companions if you lost anyone along the way. The final confrontation demands the combined Netherstones and a choice: dominate the Elder Brain and become a new Absolute, destroy it and free everyone, or let the Emperor/Orpheus make the sacrifice. Every companion's arc converges here. Every choice you made across three acts pays off or costs you. High Hall is where the story ends, one way or another.
