The Tamazians are a lot like the Sumerians in that they are the first to settle and live in the delta. Also the Tamazian lifestyle is like that of the Sumerians. However a lot of things about them are like ancient Vedic and Hindu culture, a rigid caste system chief among them. They also have similar purity rules. They also have some aspects similar to the Israelites in that they were brought to their current homeland by their deities and see it as a sort of promised land.
The Vabbians are actually more like the Semitic invaders then any Indo-Europeans. The Semitic speakers invaded and founded such cities as babylon and Akkad, actually in the region I've made the city of Arkech has some similarities to Babyl. A giant tower built by slaves from many nations, and a city of magic users.
Sabylians do have that Hittite flair. But also a bit of Persian, same with the Sinatic speakers.
In truth each ethnic group is a mix of peoples and customs.
The Vabbians have more that sort of relation to their Gods. Ziel is the uncaring passage of time, cruel father time dealing out everyone's fate, no matter how cruel. And Nazrael, while enchanting and sexy is also passionate and at times capricious, like the sun it gives life but burns your skin and dries the land.
I do plan to add some things about Mizarom though, He frequently delivering punishments to both the living and dead.
In a way I'm trying to combine a lot of mythology. Part Mesopotamia, Part Canaan, Part Persia, even a bit of Hindu.
Technically the Gods are unknown if they specifically created the world or are just powerful entities who interact with it.
