I started to come up with a background to help me get inside his head. It can be changed, but one idea I like is that he's done a little of everything. He'll probably be multi-classed up the wazoo, or at least have a few. I was also looking at Harper Mage in FR:CS, maybe Loremaster, and maybe a single level of Alienist (Tome & Blood) for fun. Another background idea was that maybe he comes from a rough place, but in a natural sense. Born in the wild forests, most of his siblings are killed off from literal predators. The family "escapes" to a more urban environment and he begins his education. So he's got a little bit of survival skills and knows about the real world, but he still prefers his books.
Any ideas or suggestions?
