Ah, so you've decided to meet your end in battle after all. It please me greatly to see such misplaced valor, human.

~ Demise
“
Extraordinary. You stand as a paragon of your kind, human. You fight like no human or demon I have ever known. Though this is not the end. My hate... never perishes. It is born anew in a cycle with no end! I will rise again. Those like you... Those who share the blood of the goddess and the spirit of the hero... They are eternally bound to this curse. An incarnation of my hatred shall ever follow your kind, dooming them to wander a blood-soaked sea of darkness for all time!
