Everything needs a backstory these days but the truth behind Darth Vader's castle on Mustafar could end up having major ramifications for Star Wars Episode IX. We first visited the Sith Lord's home in Rogue One: A Star Wars Story but Charles Soule and Giuseppe Camuncoli's Darth Vader #22 reveals that he's hoping to use it to reunite with his dead wife, Padme Amidala.
On the advice of a mysterious Sith artist called Momin, Vader is hoping to tap into the locus at the planet's core so he can tap into ancient powers which will help the villain pierce the veil of death and communicate with the woman he murdered in anger and the mother of Luke and Leia Skywalker.
The comic also confirms that there's a very good reason Vader's castle looks like a tuning fork; it's because it is! The Emperor appears to be aware of his apprentice's plan so whether or not he's being manipulated is hard to say. However, if Vader does manage to reach Padme, what if Kylo Ren ends up visiting there in order to speak with his grandfather or even Supreme Leader Snoke?
There have been rumours that we'll see Ren visit Mustafar in Episode IX so we'll just have to wait and see but there has to be at least a slim chance that these comics shed some light on what comes next!
