User blog comment:Dovahsebrom/Theory: Who is Konahrik?/@comment-84.202.99.234-20170613132739

I personally think that Konahrik was the chief dragon priest, but he grew to despise the harsh treatment of the mortals by the dragon priests and dragons and began secretly spreading negativity against the dragons, planting the seeds for the Dragon War. Alduin figures this out, and orders the other dragon priests to kill him when they all gather at Bromjunaar (Labyrinthian). The other dragon priests except Krosis (Which means sorrow) are happy to do this, hence his name. He still agrees to do so of course. Problem is, when the dragon priests spring their trap, Konahrik proves far too powerful for them to defeat, fighting them to a complete standstill. Alduin has to get involved, but realizes that Konahrik may make a better asset than a corpse. He then orders the other dragon priests to curse Konahrik, binding his soul to his own mask and killing his corporeal body. The whole 'need-all-the-masks-to-get-Konahrik's' thing is basically a safeguard to make sure no one with the magical know-how could resurrect him, and that Alduin could have access to Konahrik whenever he pleases.
