Open World Human RP Planning

Okay so what i had in mind was that aside from the open world map that Orion provided, I had the idea for this to be a rp in around the 18th century tech wise, just to try and keep with rules, and then mostly?? it was up to speed with our own time in terms of a lot of the basic culture. I already, kinda had a place for where the rift opened up and if we get a specific year for this world? I can tell you when it opened and closed.

I thought this out a lot more from when i pitched it, but its still pretty open in terms of in-depth lore and history.
