Sorry if I sounded vague. For time frame, I'd like to think of it as a futuristic scenario where humanity has evolved. Again, it's a society that practices both magic and science, but these two are ultimately intertwined. For example, the ability to pass through walls is granted through a technology that increases the movement of molecules or something along those lines. Basically, it's magic but it's explained magic in a future society. Despite this though, true magic still exists in the world but it is rare to see someone practicing it. Society looks down on those who do not incorporate both technology and magic, and instead focus on only one aspect.

Zyaxomort is considered a God figure in this world, though there is many doubt to its existence. Furthermore, it exists as more of a concept than anything else. The Ultimatum however is very much real and serves as the authority or government controlling society and all other aspects. Because of its vast technology and power, some have even related the religious concept of Zyaxomort to the rule of the Ultimatum.

Hope that explains things and please feel free to ask more. Sorry I wasn't more clear.
