I think Hyadelyn just hit the proverbial jackpot when she gave us the blessing, and wasn't someone soul she specifically went out her way to try and give it too. Having it be a coincidence would be better than her actively choosing and falls in line with what Elidibus said in 5.2 that she is always calling out for anyone who listen, we just happen to have Azem's soul just like Ardbert did.

Now all this talk has me wanting to ask Venat/Hyadelyn another question, did she want us to kill the Ascians or just stop them?
