[Revenge of the Sith] how do the events and galaxy change if Grievous actually killed Obi Wan?
gpt
When Padme goes to confront Anakin (now Vader) on Mustafar, Anakin convinces her to come with him and that the Jedi turned on the Republic. She doesn’t know and will never know that he killed younglings at the temple. She goes with him and gives birth to Luke and Leia, but would still die.

Palpatine needs Padme to die to fully push Anakin to the dark side so she can’t live anyways. She must die in child birth.

Anakin raises the twins as power force users in the dark side. The Rebellion is crushed by Vader and his two children. Galaxy falls into permanent darkness as Yoda is eventually hunted down and killed.

The spark is out.
