I recently made a bit of a breakthrough and put the finishing touch on my sequel mega-edit, namely how we transition from TLJ into TRoS and the context of Kylo’s final prayer to Vader’s mask.

After receiving a mysterious broadcast in his darkest moment at the end of TLJ Rekindled (thanks to poppasketti), Kylo Ren (using footage moved from a later scene) beseeches guidance from what he believes to be his grandfather’s presence, or essence, which leads him to Mustafar in search of a hidden ancient power. This in turn leads him, inexorably, to the true phantom behind the mirror, Palpatine.
