'Tis where it gets a bit complicated, really. I had sealed myself within a structure called the Crystal Tower to sleep until the star could make proper use of the technology within. When I woke, it was with memories of one who took another path. Another version of myself that had been awakened two hundred years from the time I had sealed myself away.

Thus upon awakening, that version of myself alongside the people of that age decided to send him and the Crystal Tower back in time. To undo what had been done.
