Thanks again for enjoying my content. God that video is so old, I made it before season 4 even aired. To address some of the things you said, I’ve always thought the Holy Kingdom was inspired by Korea, since it’s a peninsula that’s divided by north and south. Also compulsory military service which Korea also has. Obviously Chinese influence too with the Great Wall. Not confirmed by the author or anything just something I’ve thought. Your England parallel is interesting to consider though too. Never thought of that. Also yeah, Calca is in the trailer but barely. It’s understandable for people who don’t know who she is to not even register her appearance in the trailer. It’s like half a second. Others in the comments have already explained the gods thing. It’s a little weird and I still don’t know exactly why it was changed for other nations. Thanks for liking the content. Always like to see people getting into the lore. Stuff is so freakin complicated but makes the series so much better IMO. Thanks again.

8:32 Holy Kingdom just threw out 2 Gods out of pantheon

Awesome! We got another Overlord video. Regarding the religious difference , the four great gods are a deviation of the original six great gods. Instead of worshipping the six, the Holy kingdom religion recognizes only four of the six gods namely, God of Fire God of Water God of Wind God of Earth Additionally, contrary to Theocrasy who only worship the six, Roble Holy kingdom also have a pantheon of lesser gods like, God of Business: Existing only in the Web Novel, all trade of currency has this deity's mark. God of Theft: A subordinate deity to God of Earth. Buddha: A central figure of a variant religion, most people viewed him as a follower of the Four Great Gods. PS - above info taken from overlord wiki

Thanks

Iirc, the 4 gods are the human/humanoid race gods of the 6

Demi humans are also trying to live and human meat is tasty.
