When Darth Vader arrives, he follows the disturbance to the refinery that led to his downfall, where a man stands brandishing a sword practically his height and flowing white hair. Feeling it in the center of Vader's greatest defeat, the Emperor orders his apprentice to go strike down this threat to them. Motivation: a great pressure is felt in the force, it's power almost immeasurable that it's impossible for Sidious and Vader not to sense its disturbance in the force. Location: Mustafar, replacing Obi-Wan and Anakinīoth have their standard abilities, feats, and equipment (Sephiroth's feats will work like this (remake feats and movie feats take priority, older games come second to help prove points, with Dissidia being used only as a last resort to help clarify feats, equipment, etc.))
