It's worth remembering that the unsundered had no memories of Meteion when they were alive, and yet Amon was able to remember her. This includes moments on Elpis that none of the unsundered were present to witness. 'It was only when I was granted the seat - and memories - of Fandaniel that I knew these visions to be true.'
