I’m making progress on the editing for Mortis now.
I’ve just learned that the dagger, in the original version, does have metaphor assigned to it! Its altar is reminiscent of the Ring of Fire from the Wagner opera ‘Siegfried’, which Siegfried passes through to reach the valkyrie Brunnhilde, “who shall work the deed that redeems the world.” Our dagger, therefore, represents Obi-Wan’s ability to redeem Anakin, and his failure to wield it properly in this metaphor-world represents his future failure to prevent Anakin’s fall and the events that follow.
