Ragnarok being the WIP name, of course. I've got some ideas mulling around for writing a story. The main ideas boil down to a Ragnarok-esque war of the gods has happened, but the world itself continued. Now the world is in the throes of tumultuous war upon war, the World Tree is dying, the great libraries of the world have been set aflame, etc. Basically, the world has been thrown back into some WAY dark ages, and all in all, the world is boned. But now people have begun to take on the mantles of godhood, reinstating themselves as the new gods.

So, my question before I begin mapping a world, is this: If the gods of a world died in a war of insurmountable proportions, how do you think the world and the terrain would alter?
