What are the consequences of letting the Emperor control the Elder Brain in Act 3 of Baldur's Gate 3?

In Baldur's Gate 3, the decision to let the Emperor control the Elder Brain in Act 3 is one of the most significant choices you can make, with far-reaching consequences for the story, your companions, and the world. This choice occurs during the climax of the game, where you must decide whether to side with the Emperor, a mind flayer who has been guiding you throughout the story, or to pursue other paths, such as destroying the Elder Brain or seeking alternative alliances. Letting the Emperor control the Elder Brain leads to a specific ending where he becomes the dominant force in the world, reshaping it according to his will. Here is a detailed breakdown of how this choice unfolds, its consequences, and strategies to navigate it.

To reach the point where you can let the Emperor control the Elder Brain, you must first progress through the main story in Act 3. This involves completing key quests such as infiltrating the Absolute's stronghold, gathering allies, and confronting the Elder Brain. The Emperor will reveal his true nature as a mind flayer and offer you a choice: use the Netherstones to dominate the Elder Brain and allow him to control it. This choice is not made lightly, as it requires you to trust the Emperor, who has been manipulating events to his advantage. The mechanics of this choice involve dialogue options and narrative decisions that align with the Emperor's goals. You must choose to side with him over other potential allies, such as Orpheus or the Githyanki, and reject their offers of assistance.

One important consideration is the impact this choice has on your companions. Many of them will react strongly to the idea of letting a mind flayer control the Elder Brain, as it goes against their moral compass and personal goals. For example, Lae'zel, a Githyanki warrior, will vehemently oppose this decision, as it undermines her people's struggle against mind flayers. Similarly, characters like Shadowheart and Wyll may express discomfort or outright hostility toward the Emperor's plan. To mitigate these reactions, you will need to have built strong relationships with your companions throughout the game, using dialogue and actions to earn their trust and loyalty. This can involve completing their personal quests, supporting their goals, and making choices that align with their values.

A common mistake players make is underestimating the Emperor's manipulative nature. While he presents himself as an ally, his true motives are often unclear, and his actions are driven by self-preservation and power. Trusting him blindly can lead to unintended consequences, such as alienating your companions or losing control of the situation. To avoid this, it is important to carefully consider the Emperor's advice and weigh it against other options. For example, you may choose to explore alternative paths, such as freeing Orpheus or seeking the help of other factions, before committing to the Emperor's plan. This allows you to gather more information and make an informed decision.

Advanced techniques for navigating this choice involve optimizing your character build and combat tactics to handle the challenges that arise. For example, having a high Charisma score and proficiency in Persuasion or Deception can help you convince your companions to support the Emperor's plan, even if they initially oppose it. Additionally, preparing for the final battle against the Elder Brain is crucial, as it is one of the most difficult encounters in the game. This includes equipping your party with powerful gear, using buffs and debuffs effectively, and coordinating your actions to maximize damage and survivability.

From a D&D rules perspective, the Emperor's control over the Elder Brain reflects the concept of psionic dominance, a powerful ability that allows mind flayers to exert control over other creatures. This is consistent with the lore of mind flayers in Dungeons & Dragons, where they are known for their psychic powers and manipulative nature. The game's implementation of these mechanics is faithful to the source material, providing a rich and immersive experience for players familiar with the tabletop game.

In conclusion, letting the Emperor control the Elder Brain in Act 3 of Baldur's Gate 3 is a complex and morally ambiguous choice that requires careful consideration of the consequences. By understanding the mechanics involved, building strong relationships with your companions, and preparing for the challenges ahead, you can navigate this decision and shape the outcome of the story. Whether you choose to trust the Emperor or pursue another path, the choice will have a lasting impact on the world and the characters you have come to know throughout your journey.
