A few paragraphs is all that's required, though you can give me more if you're feeling inspired.  The main thing is to cover the salient points: who is this person (if "person" is an applicable label), where did the advantages and disadvantages come from (the stranger ones, anyway), how'd he end up at IOU, and how is he paying for school?  (I'm going to be lenient with explanations for scholarship students who don't meet the usual IQ 13 requirement, for the sake of further wackiness.)
