Legion20
Considering this tribulation and Liths comments during the fight, I suspect that morgar is shaping lith into the guardian of the dead. Not death, the end of things, but of those who had died and needed help to pass on or be at peace. It’s a wildly different idea from where I thought his arc might go in my early speculation to Liths accention to guardian but it feels perfect at this moment.
still waiting to figure out whats going to actually trigger the tribulation. maybe its Lith's choice of what to do with the souls after the fight is over? his body should of naturally formed more cores, maybe tiamats need to use souls instead to form them, which would kind of place him in a divergent path from the rest of awakened and divine beast in how they reach the strongest. divine beast have bloodlines that compliment their magic/path to violet core, Lith's bloodline directly overrules the typical path to violet my current working theory is that lith needs souls to progress because they would act as anchors of sorts for him (and he would be their anchor as well). As shown in the last 2 chapters it seems like Lith's abilities work best when the demons have autonomy and actively try to help him. Lith has never manifested chains to those still alive, but his demons have. If he makes souls part of his core these limitations may disappear (honestly he may instantly become a guardian or pseudo guardian upon this happening since he is already under a tribulation... honestly not sure how many tribulations it takes to become a guardian)
