This was the Undertaker's speech from 1/11 RAW-- 

"They lay me down in a grave as if it would be my final resting place.... filling it with the Earth's rotting soil. They tried to destroy me, wishing I would just go away. But what is it? What have they really done? The simple minds of mortal men... they sent me back to the place that is my origin. Destroy me? The more they try, the more powerful I've become. And now, I've risen from my Earthy grave and I will slay the ones I once saved. The reckoning is upon us. The day that the Ministry of Darkness seizes the land, destroys all that you hold dear, make play things our of your heroes and devours your innocence. The plague of Darkness is coming; an all encompassing evil from which there is no escape, no mercy, no hope. Its called the future. And in the future, I will look down upon thee and I will decide whether you are an Agent of Darkness, or are you just mere kindling for my fires. The Power of Darkness shall be offered only to a chosen few. And those that resist the temptations of my Ministry, pain becomes synonymous with punishment. Embrace the Darkness and relish in the unearthly delight that pain has to offer. Resist and there are no limits to the torment you subject yourself to. Don't fight it. It will tear your soul apart. So let my servants be few and secret. They shall rule the many and the known, for I am the Reaper of men, the Chaser of souls, the Weaver of nightmares. I am the Heart of Darkness. I am now and ever will be the Purity of Evil. The Hell you were threatened with as a child is no longer an option. It is a reality, a living, breathing reality and you are all right in the middle of it. Yes, Hell has relocated to Earth. Now you will know why you are afraid of the dark and you will learn why." 

UT's speech from 1/18 RAW: 

"Poor wretched souls. Your world is polluted with rotting souls. Seven nights past, you witnessed one of these souls become one with the power of the darkness. Minion. He was once a forgotten face in a vast ocean of individuals abused by the corrupt politics of your world. Now, he sees what you cannot; he feels what you cannot. Seven nights ago, Dennis Knight ceased to exist and Minion was given everlasting life as was all of my ministry. Tonight, I speak of prophecy and what I will shall be done. The sacrifices are not over. And the ceremony has been scheduled. For all who walk on the mortal side of life, take heed. On January 24th, the next sacrificial lamb with be led to slaughter. And your simple minds won't allow you to believe who the next victim will be. So attend if you dare. Resist, and you subject yourself to agonizing pain and extreme suffering. So until we meet again, accept the Lord of Darkness as your savior. Allow the purity of evil to guide you."
