I was going to write an entire chapter, but this will do for now.
I think this wraps up the background story for Louie so far.

---

"Yes Tobias, I can hear you now." Louie mumbled to himself after another night chained to the walls like a beast.
Insanity had been his closest companion for years and now it seemed it had taken a corporal form and it was feasting on the things that belonged to him.
The being outside the wooden door to his makeshift home had to leave before it succeeded in it's malignant plan.
The voice of his old mentor soothed Louie in the night as a shriek of pain came from his living room.
"You are not an evil person. Are you?" Louie shook his head in an answer to his own question and with newfound strength and confidence he rose to his feet and gave a firm tug at the shackles that bound him.
Dirt fell down over his face and he growled as the iron cut into his wrists.
"Do not disappoint me Louie, I have taught you more than this." He pulled at the firm rings again and clenched his teeth. Tears sprung in his eyes as his wrists started bleeding.
"Tobias, I do not have the strength anymore." Louie sank down on his knees, his arms being held up over his head and he let his head hang in shame.
The door unbolted behind him and the shadowy figment of his deluded mind walked in with fresh food.
"You can not be real, begone foul being." Louie spoke with little enthusiasm, he was ready to give up and let go.
"If I were not real, would I be able to do this, fool?" He forcefully threw yet another young maiden at Louie's feet. Too tired to struggle she let herself fall towards the floor.
The vampire stood up, devoted to his intentions never to feed on an innocent being again. "Do what you will to me, I refuse your gift."
"So much spirit, so much... good." The shadow told him, repulsed.
Tobias' voice spoke to Louie again. "Make a stand, we need you. We all need you." Louie looked up and for the first time the shadow saw in his eyes the thread that he posed.
He rose to his feet and broke the shackles behind his back, he growled and slammed the shadow into the wall.
"I refuse insanity, from now on I will be in charge of the things I do." And with these words, the shadowy figure and the dark part of Louie's soul disappeared.
The girl at his feet let out her last breath and lay motionless on the floor, her peering eyes on him. A pool of dark blood underneath her, diluted because of the sweat and tears.
He closed her lovely, big, blue eyes with the tips of his fingers and took her in his arms.
He wept because he could not be there for her sooner and carried her out into the garden, hiding behind the overgrown plants out of sight from the curious eyes of the villagers like he always did when he went out.
Louie carried her into the mausoleum and put her in the coffin that had once belonged to him.
Her beauty had not yet ebbed away a half hour later when he put a lid on the casket and hid her from the face of the earth until her remains had turned to dust.
"Tell me what to do now Tobias and I will listen." He waited for hours, the sun set and it rose again. He fought against the oncoming hunger for blood and the insanity.
On the third day of calmth and patience a voice spoke to him, much clearer than that of his old mentor. Much more angelic and pure as the soul of a newborn hare.
"Never forget which powers you possess, child of Carrotus." She soothed him to sleep echoing the word 'Patience.' until he had slumbered off.
