>A-Eon didn't reveal it so far (no idea why), but as there're still discussions on this and questions occuring at various places I'm going to tell how I perceive this "quite a story" came along in chronological order:

Everyone should keep in mind that Andreas is probably right about this sequence of events (in fact, his explanation is the only on that fits the facts), but this is still speculation.

Obviously, for the reasons stated in Andreas' summary, Trevor and the rest of A-eon haven't been able to reveal some of this information.
