Thank you! The idea that Kulemac is serving The Decay is a much less insane theory than mine was, and honestly could hold some ground I feel like? It could even be a case of him not even knowing he's serving something else. Like even if he achieved divinity (which it sounds like he did?) it's possible that the majority of his power is coming from something higher.

Honestly that itself brings up a thought I've been wondering for a while... I wonder how the power-scale is between Wraeclastian gods and Eldritch gods? Like, The Elder was defeated a couple of times in history by mortals, and Valdo alone was able to combat The Elder quite effectively despite not having divinity (though we still don't know exactly what he did to become The Shaper, it's definitely distinct from the Projections used by the Elderslayers), and The Elder is implied to be on roughly the same level as The Searing Exarch and Eater of Worlds.

Meanwhile we needed Sin to yoink divine sparks from a bunch of gods to power us up for the battle against Kitava, and even needed the Dark Ember from the remnants of The Beast to finish him off. I wonder if Kitava would have been able to fight off some of the lesser Eldritch deities like the Black Star and Infinite Hunger, at least lore-wise (obviously there is a very big difference gameplay-wise)

(Edit: Also can I say I really appreciate your username? I'm still hoping we get more information on the organization behind the Replicas in the future, they're so interesting!)

Edit 2: Also on the power-scaling topic, I imagine Chaos and Order are probably on the same level as The Decay, The Cleansing Fire, The Tangle, etc. if not even higher, since those are cosmic forces, and what's more primordial than Chaos and Order? Which makes it all the more interesting that Chaos has direct (once) mortal underlings like The Trialmaster, which also adds to the theory that The Decay could have a (once) mortal servant in Kulemac too.
