I've had this idea bubbling in my head for some time now, but I'm woefully ignorant about one thing and I'm hoping someone on here can help (if they're interested in this). The foundation of my idea is a pre-apocalyptic world. Ice/snow is steadily creeping down from the north: the thousand year Ice Age that people from all over the world have foretold about in one form or another is beginning. At the end of the thousand year ice age there is supposedly going to be heaven on earth, but except for a few survivors everyone will die. And no one wants to die, they (the players and NPCs) fight against their destiny, because not doing so will be death. That's the basic premise of the story. The part I need help with is about Roman/Greek/Viking/Ect. mythology. My knowledge of this is zero, but I want to craft a world like our own, but set with these gods/goddesses and beings like monsters and demons (if they exist in those mythologies). Think God or War; that is what I'm looking for in this RP. The reason being is each player will be a Champion for a god/goddess with long life (600+ years), stronger bodies, and some powers granted to them by their god. Is anyone like a walking Wikipedia about those mythologies that would like to help? The pre-apocalyptic world doesn't have to be an ice age, I chose that because it is easy. If either of those mythologies have an end of the world scenario that better fits my god -> champion mechanic feel free to say so so I can change the ice age to that.
