I haven't read everybody's posts, but what about a rogue/wizard? I have an idea for a young human, orphaned and brought up by a heartless innkeeper, who develops rogue skills initially (sneaking around and breaking into rooms, picking pockets, and so on) but is actually very bright, and fascinated by the acquisition of knowledge.
I would see him leaving his "father" as soon as he possibly can, and somewhere along the way discovering the way of the wizard.
By the way, I played first edition for several years, had a long hiatus, and then came back in time for 3E. I play (rarely), DM (occasionally) and play a number of PbPs here, as you can see from my sig.
I can post daily (usually) and often will post more than once a day. My posts tend to be longish, with dialogue and roleplaying where appropriate, but there are times when RL intrudes, and my posting is a bit patchier. Having said that, a regular posting schedule keeps me in character, and so I find it easier to post, even if only briefly.
