I love the implications of the seven birds being from a more technologically advanced world than faerun (knowledge of TV, understanding of machine guns "count the shells", using microphones ect) because how many things was Lucretia not able to erase? Across 99 planes, it's impossible that she managed to get everything. And how well was she really able to introduce the more medieval concepts of faerun into their memories?
What did the THB think everyone was doing just waving swords around rather than pulling out guns; did they just accept it and move on? Imagine Lucretia trying to explain them to a weapons development department of the BoB to equip her employees. Lucretia, a records keeper, who cannot have a great understanding of the inner workings of firearms. Vaguely describing rectangles that explode to a reception of horrified looks.
Or Taako repeatedly asking Sazed to supply him with various kitchen utensils he insists are vital for the recipe that just Do Not Exist. Magnus, complaining that he can't play little games on his stone of farspeech, while everyone around is completely baffled at the concept. Everyone around them not only not getting their pop culture references, but being fundamentally incapable of understanding them.
I just think there is something so funny about them functionally time travelling and then promptly forgetting they were from a different era at all. And just. Having to get on with it.
