Meanwhile, Supreme Leader Kylo Ren has traveled to Mustafar, chasing whispers of a rumored Imperial fleet that would allow him to destroy any threat to his power…
Hmmm…not sure about this. Wouldn’t it be better to mention a hidden clue to an unknown Sith Planet aka Exogel instead of an Imperial Fleet. As Kylo did not know about the hidden fleet until he gets to the planet. The Wayfinders gives direction to a
hidden a Sith planet that is not on any known maps.
