Should You Enter The Planecaster In Baldur’s Gate 3?

The decision over whether to enter the Planecaster in Baldur’s Gate 3 is more complicated than it seems. The party may be faced with this choice if they progress in the githyanki crèche questline, which eventually puts them face-to-face with the githyanki god-queen Vlaakith. Using Shadowheart’s mysterious Astral Prism, which thus far has seemed to protect the party from Illithid influence, Vlaakith opens a portal to the Astral Plane, and demands that the party step inside and kill her prisoner. Unless the player has been following the lore very closely, it’s difficult to understand just what this decision entails until they’re already on the other side.
