"I was born in 1712. My deafness lead me to do something... Wrong. I would regret this for years... No centuries to come."
A white kitten, 7 months old, was following his mom through a forest in Nicaragua. He was deaf, he could hear nothing. His mom stopped, and signaled for the kitten to stay there. The young cat sat down and watched his mother run off. Then, for the first time in his entire life, he heard a sound. When he looked to the right, he saw a cave, shining a glorious light out of it. He wanted to stay and wait for his mother, but the kitten couldn't fight the temptation. He wandered into the cave. He kept following the light, knowing it was guiding him somewhere. Seconds of walking turned into minutes, and one hour later he finally got to the end of the cave. There was a large lake in the cave, and crystals hung from the ceiling to give light to the cave. The kitten was slightly scared, he wanted to turn around and run away, but he couldn't find the will to leave. He heard a voice. "Hello kitty. Why are you frightened. Embrace the light. Embrace MY light". The kitten had never felt so much fear, yet so much comfort at the same time. "You. You are deaf aren't you?" The cat nodded. "How would you like to hear? Finally hear the loving voice of your mother? All I ask is one thing". The kitten sat, confused, but listening. "I want to give you a life that will last... forever. And you will pay in blood...". The kitten never got a choice, everything went white. He was then infected by Bloodlust, a disease only he has. He would live forever, but he had to drink the blood of things with no lethal diseases, freshly killed or still living, and he could never drink from the same life form twice.
This cat would go on to be known as Overkill.
