Players who reach the githyanki crèche in Baldur's Gate 3 eventually meet Vlaakith, and she makes the Planecaster look like a simple doorway. It is not. The decision sits at a strange crossroads in Act One: refuse the god-queen, and Lae'zel may break; step through, and Tav meets the Dream Visitor face to face. In 2026, years after launch, this moment still sparks debate because the obvious choice is not always the safest one. The good news is that the Planecaster itself is less of a trap than Vlaakith's command. The player can enter, listen, and still refuse to murder the Guardian. That route keeps the most options open.
The Short Answer
The best route is usually to enter the Planecaster and spare the Dream Visitor. Entering does not lock Tav into Vlaakith's plan, and it keeps Lae'zel in the party. Refusing outright can push the githyanki fighter into open hostility, which can end her story permanently. Sparing the Guardian also avoids an unnecessary confrontation and leaves room for later storylines. 🎮
| Choice | Lae'zel's reaction | Main consequence |
|---|---|---|
| Refuse the Planecaster | Strong disapproval, possible hostility | Lae'zel can die and leave the campaign; githyanki story content can end early |
| Enter the Planecaster | Approval | The Dream Visitor conversation happens; Vlaakith attacks after the party exits |
| Enter and spare the Guardian | Approval | Keeps party options open and preserves later Guardian-related content |
What Happens If the Party Refuses the Planecaster
If Tav refuses to enter the Planecaster when Vlaakith demands it, Lae'zel disapproves. This is not a mild frown from a companion who dislikes the decision. She may immediately turn against the party and side with Vlaakith, her queen. If that happens, the party has to kill her to move forward. That outcome removes the githyanki fighter from the rest of the game, cuts off her personal story, and makes any future romance with her impossible. It is a harsh consequence for a choice that can feel like simple caution.
The refusal path also leads to a difficult fight against a horde of githyanki warriors. The party can survive, and the campaign can continue through the Mountain Pass and into Act Two, but the githyanki storyline effectively stops there. Players who skip the Planecaster may miss later content involving the githyanki, including threads connected to Orpheus and Vlaakith's larger schemes. Refusing is not a dead end for the whole campaign, but it is a dead end for several character and faction stories. ⚠️
What Happens If the Party Enters the Planecaster
Entering earns Lae'zel's approval. The party appears on an abandoned slice of the Astral Plane and faces a glowing portal. Through it, Tav hears the Dream Visitor, the Guardian chosen during character creation. The Visitor warns Tav not to come through and, more importantly, not to carry out Vlaakith's orders. Naturally, Tav can step through the portal to see the person and place that have appeared so often in dreams.
The Dream Visitor admits disappointment that Tav did not heed the warnings, but the conversation quickly becomes more informative. The Visitor explains that they stole the Astral Prism from Vlaakith. The god-queen wants it back because she believes it can help defeat the Illithid Empire, as her gith ancestors did before her. There is a crucial flaw in that plan: Vlaakith does not actually know how the Astral Prism works, and only the Dream Visitor understands how the gith once used it. What is more, Vlaakith does not plan to let Tav or Lae'zel stick around long enough to learn the truth. Once the party leaves the Planecaster, Vlaakith and her subjects will attack.
Simply entering the Planecaster and talking to the Dream Visitor does not ruin the overall storyline. The Visitor may be disappointed at first, but that disappointment fades quickly. Tav can choose to trust the Guardian further after this event or eventually turn against them later. The next decision inside the Astral Plane is the one that carries more weight.
The Guardian Choice: Kill or Spare
At this point, the Dream Visitor kneels and hands Tav the sword from their back. It is a clear challenge, and the player can decide what happens next. If Tav chooses not to kill the Guardian, the conversation continues peacefully. The Visitor offers more warnings about Vlaakith's schemes and then lets Tav go.
If Tav does choose to kill the Dream Visitor, the sword goes into their chest. The Visitor muses that they expected more from Tav, then teleports away and returns completely healed. They are clearly upset, but they still speak plainly because they need their own plans to survive. This choice may strain Tav's relationship with the Guardian, but it is not irreparable.
After returning, Lae'zel has questions. Tav can attempt to deceive her, but a Difficulty Class 12 Persuasion check to explain the truth is usually the better approach. Failing that check can still cause Lae'zel to turn against the party in the coming battle with Vlaakith. This is a reasonable moment to reload a save if the roll goes badly, because the cost is not just a few lines of dialogue. It can reshape the rest of the act.
The Recommended Route
The strongest route is to enter the Planecaster, refuse to kill the Dream Visitor, and then face Vlaakith with Lae'zel still on the party's side. Entering is not the same as obeying. It gives Tav a chance to understand who Vlaakith is, what she wants, and why she needs to be stopped. It also keeps the githyanki storyline alive for later chapters.
Sparing the Guardian is the better choice because it keeps options open. The party cannot permanently kill the Dream Visitor anyway, and approaching them peacefully signals trustworthiness. The Guardian may be mysterious, and their interest in Illithid powers may not win them many friends, but Tav learns more about them later. Staying in the Guardian's good graces can also make a later encounter easier and help unlock a set of powerful Illithid abilities. For players who want to avoid a bad ending, keeping the Dream Visitor alive is the safer bet. ✅
Both Vlaakith and the Dream Visitor may return later in the game. They are both seeking an end to the war, and Tav can still choose a side. Githyanki player characters who swear fealty to Vlaakith might prefer to follow her orders without question. Mistrustful Tavs might avoid the Planecaster entirely, and some players may take the Underdark route to the Shadow-Cursed Lands and miss this quest altogether. In 2026, the advice remains the same: enter the Planecaster, hear the Guardian out, and spare them. The final choice still belongs to the player, but that path preserves the most story, the most companions, and the most future options in Baldur's Gate 3.
