Speculation time: Part II
Watch this:
Near the end, Hector turns the Curse into "something harmless". But, as per Julia's speech at the very end, we know that the curse still took root in the hearts of humans and would take time to disappear. Even so, it does look like Hector rid the land of something extremelly powerful.
My question is: Could we actually figure out what did Hector turn the Curse into? Sure, we see that ball of light and we have a big exploding show, but... What then? That's it? Just a bunch of lights? We know his technique infuses a soul into something supposed to come to life, but we see nothing come out of it, just a bunch of lights.
Also, have you dudes noticed that the Devil Forgemaster Crest appears under the ball of light as Hector holds it?
And, something minor here: In english Dracula says that "his soul may return to the abyss" but in japanese he uses the word "darkness" ("ankoku"). Some people think that the abyss he's talking about is THE Dawn of Sorrow Abyss. But no, he's probably being general here with the use of the word "darkness".
