Mmm... Easy... I'm not sure, but this is possibly an Emperor (or at least someone with high authority), maybe a feared individual, who undergo great sacrifice to achieve his goal. She is also talking about judgement of heaven, which I interpret as having suffered a prejudice so big only the divine can cleanse it fully.

I don't know what an EX Oblivion Correction means, but I'm sure it goes beyond what a human being can take to achieve revenge... mmm...

I have a candidate in mind but let's ask this : is there a famous sword attached to this character?
