For example, how the Zeffo in the tomb of Kujet seem to be frozen in pain in front of Kujet, similar to the Jedi and Sith below Malachor’s surface. Or how Momin’s attack on Mustafar might have been the war that caused Lord Corvax’s death, jump starting Mustafar turning into a lava planet. Or how Momin’s plan was to freeze the Mustafarians in their moment of most pain and dread, similar to what happened on Malachor and Dathomir (the tomb), which means he could’ve created the super weapon on Malachor and the technique that Kujet used.
