Did Elysia sacrifice herself?

I'm curious to know, did Elysia truly make the ultimate sacrifice? The story hints at her willingness to put others before herself, but did she actually go through with it? Was there a moment of hesitation, or was her decision to give up everything for the greater good an absolute one? And if she did indeed sacrifice herself, what were the consequences of her brave act? It's a compelling narrative, and I'm eager to hear more about the depth of her commitment and the impact of her decision.
