To give you a little background on the events of this Baldur's Gate 3 opening cinematic, the mind flayer performs the ceramorphosis. The tadpole he puts in his prisoners' eyes will end up turning them into mind flayers too — their sworn enemies arrive: Githyankis. Their mission is to hunt them down wherever they are especially. The situation is even more delicate here because one of them is aboard the ship, and she seems to be an important character in the story!
The player wakes up after the crash, with a time bomb in his head in the shape of the tadpole.
There is still no release date for Baldur's Gate 3, but it will be available in Steam Early Access in a few months. It's not planned on consoles, just on PC and Stadia for the moment.
