I really like these ideas, but holy fuck info dumping. You need to exercise brevity, especially with descriptions. All the information you need to recall in am AU in addition to your canon is part of why games like these have failed in the past. My suggestion especially for locations would be to use images and do a small blurb for each.

Also, some nontraditional classes would be great. Steal some ideas from Final Fantasy sand Tales of and the like. Or at least be inspired by them.
