Just a few concerns to take care of, first, for his AU history, as outlined, it would work if he was from just BEFORE the time of the Savior. Post-Savior, that kind of tech simply would not be available, and a settlement that close to Union simply would not exist (it's worth noting too that the Mausoleum is in an area that's part of the Old City so it's directly underneath Union). I would suggest he have had the form change during the war, and have him have been active at that time.

Also, both of the samples, especially the first person sample, are a bit short, I would like to see stronger samples on both. If desired, you may instead answer 6 of the questions instead.
