Cuttlefish That Loves Diving
I'm going to toss out wild speculation. What if the lines of Lumian's "fate" were split. One became the instigator of the ritual, and the other was the original vessel or sacrifice. At any rate, whether this person is just a doppelganger or the "real" or "original" Lumian, the version that we know and love is the one I believe will usurp or reclaim his rightful place. Thanks for the chapter!
