Kulle's Journal
Part 1
Finally, I have unlocked the secret of the soulstones once given to the Horadrim by Tyrael. An impressive creation, to be sure, but one that I am certain can be duplicated. No, not just duplicated - improved upon. My soulstone will be made to contain the souls of many demons, or even angels! -- Zoltun Kulle
Part 2
I believe with this soulstone I will finally be able to unlock the true power of man. In ancient times, our kind possessed power unmatched in this dreary age. With the soulstone, I will be able to elevate myself to the strength of my ancestors. -- Zoltun Kulle
Part 3
The Black Soulstone will be my greatest work, my legacy, and my gift to humanity. There will be wars to come between man and the creatures of Heaven and Hell. The power housed within my stone is the very thing needed to set mankind free from demons and angels forever. -- Zoltun Kulle
