Ok, explain to me what he needed to hijack the stormfather's visions for, which somehow the Stormfather didn't notice, so that he could try and make either a Bondsmith or Herald. Yet felt no need to rush them, but rather focused on finding the perfect individual to fit the job.
What could that accomplish that somehow forming his own kingdom is faster at?
If he has his blade why worry about not having the right person for the job? He could make anyone the right person.
His plans did not change immediatly, he dicided that Gavilar was the wrong person, he says "If I try again I will do it differently" at 57:40 He still wants someone to say the words.
Additionally Gavilar is probably the only one who thinks he is going to become a Herald "Oh Gavilar, there is so much you do not know. So much you assume, and the two never do manage to meet." 53:02
