It's called using historical uncertainty as a plot device, lot of historical novel do that by fill the blank of history record with their own intepretation.

In this case they explain that the reason Abigail are gone from record simply because she left with Carter. They explain that Abigail throwing fit on the original salem witch timeline is caused by Great old one and she simply unaware of their existence try to reason it as caused by witch because not in her wildest dream that she's a vessel for cosmic horror. That this singularity are made by Raum to let the great old one descend rather than letting whatever happened to original Abigail on history to happen that clearly failed to summon the great old one in proper history.
