The Lore of the Elder Brain
The Elder Brain is one of the most important members of the Mind Flayer community, being equally worshipped and feared as a potent psychic entity. They are dominant, disembodied viscous spheres with rolling and swimming colonies of Illithids guiding them. They are both the heads and the wise of the colony, and they control the Illithid colonies through telepathy. As for the greater context of Dungeons & Dragons, Elder Brains are formed when illithids converge and pool their thoughts and experiences into one being. Their prime objective is expanding such a brain, an overall self-sufficient species.
In BG3, the Elder Brain—called the Netherbrain—incorporates more sinister goals. First captured by three powerful entities known as the Chosen of the Absolute, the Elder Brain alters the initial Fate of the Mind Flayers' control, elevating them to complete control of all sentient life in Faerûn using tadpoles. The protagonist's journey finally takes shape when it directly confronts this huge monster, intending to conquer Baldur's Gate.
Role in the Main Story
The Elder Brain's power grows ever more potent as the plot progresses. It orchestrates the events that nearly destroy the city of Baldur's Gate. Wielded by the three Chosen of the Absolute, Orin, Gortash and Ketheric Thorm, the Netherbrain becomes a lethal weapon of mass control.
To confront The Elder Brain, the players should ultimately defeat 3 of the Chosen who possess Netherstones Confronting the Elder Brain. This opportunity is the game's last mission and is called Confront the Elder Brain. It becomes apparent that there is no way to bring the Elder Brain down in a straightforward war; the only thing that will do it is a Mind Flayer who has suffered terrible trauma and has been gifted by the magic of the Netherstone.
The Final Battle with the Elder Brain
The battle with the Elder Brain is one of the most intense moments in the BG3. The battle starts in an underground location known as the Morphic Pool, where the Elder Brain dwells. To reach the Elder Brain, it is necessary to fight through hoards of enemies, including Death Knight Stalker Svignee and Mind Flayers.
Once the players have approached the Elder Brain, they must decide whether to destroy or attempt to control the Brain. However, before this decision can be acted upon, it is necessary to engage in combat with the psychical aspects of the Elder Brain. At one point, players can attempt to dominate the Brain via DC 99 check, which reduces the Brain's HP and gives them a slight advantage.
Psychic attacks, Mind Flayers, and waves of minions make the battle extremely tough. The Emperor Illithid, who teams up with the player, suggests that consuming the essence of Prince Orpheus, a Githyanki prince imprisoned in the Astral Plane, is the only option to become powerful enough to conquer or defeat the Elder Brain.
Decisions and Consequences: Destroy or Control?
The choices taken by players during the last battle are very impactful in terms of the narrative:
Control the Brain: This route involves becoming a Mind Flayer and using Orpheus or the Emperor to control the Elder Brain rather than destroy it. This achievement gives the player control of the Brain but makes them one of those beings they have been fighting to overcome.
Destroy the Brain: The other alternative left is to destroy the Brain. If the player refuses the emperor’s offer to eat Orpheus, they can rescue him and have Orpheus, or even a player character, become a Mind Flayer. In conclusion, the Brain is finally erased in an ending.
