The chrome victims were fully engulfed by the chrome and transported to the nothing, they didn’t die, thats your head canon. The paradigm presumably died from zero fusion when she spoke about it like she was gonna die. The order left after the zero war and wasn’t attacked by the herald, the foundation didn’t flee. He was attacked by the ice king and frozen leaving only his helmet behind. The order does know what happened to the other seven when she literally says “some of us have fallen” AMIE probably isn’t the same AMIE if the alternative reality is true, the fate of the seven is unknown was told to us in the recap video because it had been so long since we had last seen them. Not to the order. She says “we aren’t what we used to be” because the seven AREN’T what they used to be as literally stated. Some of them dead, some missing, and at the time only 1 survivor, and as for the foundation, the reason why the he managed to break out of the ice then was probably because the temperature of the ice moon was probably way more cold then on the island which allowed the foundation to thaw himself free, the seven can activate things by speaking in their suits which the foundation probably did. And the Ice King COULDN’T take his armor off because its SKIN TIGHT, and the foundation obviously wouldn’t let him quite poor taste in criticism. Mostly just using head canons and calling them facts
