Threats:
"Fear me, for I am your apocalypse!"
"It pains me to know that your unclean blood will stain this place."
"Your skull had better not be thick enough to nick my weapon."
"Listen, [AUDIENCE:RACE]! The whispers of the wind speak only of your death. The world itself begs for your blood!"
"Once I've killed you, I will hunt down your friends and your family and they will curse your name before they die long and painful deaths."
"I grant you a moment to consider your path and repent of your sins. Good. Now you will perish."
"If only there were a bounty on your head. Then, I'd soon be a little richer and a LOT happier!"
"I salute you before your death."
"Ugh, you're covered in blood and vomit! I had been hoping to clean my blade on your cloth once it had slaked itself on your blood." *note: this assumes the adventurer is just like every other adventurer... covered in the remains of previous creatures
"I am destined to be your last foe."
"Embrace the end that awaits you!"
"May the jackals feast on your flesh when I am through with you!"
"May you find your forebears in the world beyond."
"Look into my eyes and see that there is no victory for you. My determination is absolute. You WILL fall here and now and by my hand!"
"Finally, you have come to me. Know that I am your doom, [AUDIENCE:RACE]. Your training means nothing, for I am better than you. Your strength means nothing, for I am stronger than you. Your speed means nothing for I am faster than you. Your anger, fear and determination will wash against me and turn their flows to your destruction. Hope will die in your heart even as I wrench the life from your body. Yes, worm, I will end you."
