(Note: This concept is meant to be a PREQUEL to Morrowind)
Voice: Ah, Lord Indoril Nerevar. I know you. You are Azura's champion, the true Hortator and Saint to all decesendants of the Chimer.
Your voice forged and united the three Great Houses, and also made peace with the empire and Dwemer alike. However, such notions of "peace" are fraile and fleeting. You were ultimately forced to wage war with the dwarves because they believed that they could transcend their own mortality and travel off of the planet of Nirn.
Ironically, the true enemy was your own council, for they did not understand how to use Kagrenac's tools properly with my heart like the cautious Dwemer tried to do.
Lorkhan: Yes. I am also the first selfish thought of Sithis, the thought that refused to end. Nirn is my corpse, it's moons my severed limbs.
I tricked the other Aedra (planets for the lack of a better word) into giving up parts of themselves to form a new planet, Nirn. However, Nirn was actually an extension of my existence, and in my betrayal I easily ate their "presence" on Nirn, and weakend the other Aedra forever. Unfortunately, I was punished, and banished into an existence from which I could not escape: My own heart. I have been forced to grow and eat my own flesh from within so that I may survive long enough to become hungry again.
Your precious "Morrowind" exists because my heart dwells within Red Mountain. I am the blood in every vein and the selfishness in every heart. My sweat formed the oceans,and my bones degraded into mountains and eventually other life
such as yourself.
Ah, but your pathetic story is almost as ironic and sad as mine. Before you die, know that I convinced your own wife into murdering you in exchange for temporary "immortality". Know that I will eventually resurrect Dagoth Ur and spread my divine curse to all of Tamriel and beyond! I will eat in an unending feast to restore what is rightfully mine!
I wonder how you will taste Lord Nerevar, because I am starving for something different....
Give Azura my regards, tool, for she will have need of a new one after I am done with you.
