Three Kingdoms? Dayum, I really hope your poison resistance has improved thor, because I can expect that the next volume will be full of poison, and I hope you can neutralize as much poison as possible and make us readers comfortable to read it. Stay healthy Thor😍 (Honestly if it wasn't for how interesting volume one and two were, I would have skipped volume three.)
I can see where the author is going with this. If Reinhard is to take the mantle as the one and only sole god upon the Throne of Chaos. He needs to face the trial and challenges over the Four Chaos Gods role. The Sparta Arc derives at the thralls of Khorne. Where blood is spilled at the tides of carnage, insanity, and vengeance. If the Three Kingdoms period is the next arc, it's a playing field who outsmarted outsmarts. It's actually the perfect condition over Tzeench, the chaos god of knowledge, trickery, truth, lies, and so on, about a being that embodies the sapient adaptation and changes. I could see of Nurgle next play in my opinion in Mesoameric that deals the Aztec-Mayan deities. Although in Warhammer 40k lore, Nurgle awakened during the Black Plague that wiped out half of Europe population. And Slaanesh, maybe unto Extra timeline at Moon Cell, BB and Kiara.
