That was the illusion Arceus gave some people, but Noctowl didn't fool anything, Skyla and Falkner really had eternal life, invincibility and they would stay at their current things forever, and that's really true and can't be changed.
Sorry, and I can't force you all to do this, but could we all please stop the things that make stuff others say undone? That way, the story can actually move forward instead of everyone constantly undoing what others did. It's not very good if you post something, knowing that the next person will undo what you did.
