I suggest getting a map or pictures of the world. I guess you could say the world have been reborn? How much of the radiation is gone? Wastelands?
Would some past technologies have survived, maybe as relics? I like the idea, but you might want to work out how exactly you want it. Or at least write more details. ^^
Thanks for some of the ideas! For the map, I'll make one, but it will take some time and it will likely be bad. The world itself has been reborn with most of the radiation gone. Only a few spots called 'Heatzones' exist where the radiation still remains. So much so that a person dies within seconds of entering it without some kind of ward.
Some technology and cities are still around. You won't be seeing a downed bomber, but a bunker with some old tech like a computer still lay around. Some of the old world even managed to make it like Judaism(cause making religions takes time and there will be a few in this Rp). Most cities have been turned into dust and rubble with the remaining ones into walled medieval-Renaissance styled buildings. A few old buildings like the Leaning Tower still exist in those cities. Just the fact they're considered to be items left by god(s).
Another thing is robots. Yep, they existed, but most were destroyed and the remaining ones stuck in an area known as the Barrier Mountains. I'm planning on including a bestiary of fantasy creatures as well.
One thing mentioned were the Immortals. They're undying humans, elves, dwarves, etc. and the oldest are all human. They're not available for players due to their undying, insanity, and coldness towards the world. Few still cling onto shreds of their sanity, but overall are slowly losing it.
Anyways, thanks for the ideas!
