Fantasy exploration context involving mages on two sides (the "good" and the "evil"), perhaps? Nothing too grand or really, that original in terms of the premise - just something with a little plot, assuming this very broad concept has any merit, that builds up and perhaps can build up to be something more if it catches your interest. Introduces with your char being a total magical novice that is taken in by my char and trained to be a rather effective warrior for the "good" side, and the plot goes from there. There's more thoughts in my head on that point, but I figured I'd pitch this little bit out first.
