If the blessing is tied to Hydaelyn and that there was an image of her looking dark/ turn into Zodiark then getting out blessing removed could be a blessing in disguise?

We are her tied to her as her warrior of light and IF she ends up being consumed by Zodiark then that might also mean that we'll then end up automatically tied to becoming Zodiark's own warrior.

It seems like the echo is a separate thing entirely and that it really is the 1st step in communicating with otherworldly beings.
