You'll be playing as the right hand man of a god. But wait, there's a catch! You have greatly displeased your god, so much so that he/she has seen fit to strip you of all but your most basic powers and banish you to limbo. You see, in this multiverse there are an infinite number of planes and limbo is one of them. You haven't visited other planes and why would you? You come from a plane where your deity has reigned supreme for time beyond measure. The societies of your planes have adapted to the influence of your god and have structured their lives accordingly. In fact, it seems as if the entire world has shaped itself around your god.
Limbo is not nearly as interesting a place. In fact, it's the most boring place you can possibly imagine. It's white in every direction. You are floating. There is nothing and I mean nothing, else to see.
