I found the official archives. The people who run them admit that most of the records of the transition period have been lost in the Info Wars, their records are more recent. Some of the under-archivists are willing to go so far as to think it plausible that there could have been some minor things swept under the rug due to the loss of records, but I it doesn't feel like there was a vast historical rewrite. Didn't find Margot Bellarion, or what the "temptations" might have been. Sorry I didn't have time to do more looking; I wanted to check university archives, and maybe some private ones. But without knowing more specifically what you're looking for, this could be a really long search.
