THE DAMIAN CHRONOLOGY
Present Day
It was 10:30 on a Friday night. The video store was cold and devoid of business at this hour. A woman walked deep into the store dragging around a heavy box filled with tapes to reshelf. The clerk looked at his watch torturedly. He then took a sip of his Slurpee, grabbed his guitar magazine and reclined in his chair.
The clerk tensed up as he heard the electronic bell announce a new customer. Glancing away from his magazine he saw a man in is early to mid twenties, shuffling through the “bargain bin” in front of him. Judging from the stranger’s heavy black trenchcoat and long, blonde hair which is short in the back, one can assume he's a street punk. A large, wide brim fedora hat is hanging off his shoulder. We know him by the name Damian Warrington.
"Can I help you?" the clerk said irritably, his eyes never leaving his magazine.
Damian stopped in his tracks and glared at him through his thin red sunglasses. "No, thank you, I'll think I'll manage sir." Damian spoke in a Cockney accent. The clerk heavily sighed and did not respond to anything else Damian did. He then headed off to the Horror section of the store. Damian always loved how wrong horror movies were.
While browsing through the large library of tapes, he saw a beautiful Asian woman crouched over on the other end of the section, reshelving the "Faces of Death" tapes. Her figure intrigued him. Grabbing the tape he wanted, he walked a little closer to her, and silently watched her shelf for a moment. He was enticed by soft look of her face. He then broke the silence.
"Good Evening, miss" He started. She looked up at him, fully showing her face.
"Saw II is in the new releases". She automatically, yet tiredly uttered, completely interrupting him. She then went back to work.
The full image of her face froze in his mind, and a small pain in his head made him wince. After opening his eyes, the woman appeared in an elegant black dress, and her hair up in a bun. On her side and neck were large bloody gashes. He stared in horror for a moment, as his heart pounded. He shut his eyes and opened them again. She looked normal again, only looking at him a bit irritated. He dropped the tape and quickly walked out of the building. The clerk jumped out of his chair as Damian sped across him.
He dropped to his knees in the parking lot beside the store, firmly grasping his chest, and panting loudly. Saliva coursed in his mouth, and with his final convulsion, collapsed on the pavement. Slowly collecting himself, he weakly rose to his feet and hoofed it to the alley across the street, entering a door with a sign that reads "The Stake."
The Stake is an underground "blood bar", where vampires can feast on willing human "fan-girls and boys", as well as get a stiff drink. The air was pungent of blood, and sweat, at least to Damian, who has a keen sense of smell, as is usual for a vampire his age. The vampires in the tables around the bar are talking up a storm with their seemingly adolescent hopefuls.
He slumped into a stool, and ordered up a shot of Jagermeister.
“Something wrong, mate?” The bartender lisped in an Australian accent.
”A great deal” Damian weakly replied.
”That drink should perk you up then!”
Thoughts coursed throughout his mind.
1918... After all these years, the memory remains
Damian was 45 years old when she died. Her name was Akiko Kitano, his human companion. She not only was his lover, but assistant in his work as a freelance soldier. Her death was very damaging to him. Somebody merely looking like her can make him sick to his stomach with the pain of loss.
4/5/1918
Damian limped as he carried Akiko to the foyer of his house, lying her down gently. He had a large cut down and across his eye like a cross. A dagger the size and shape of a Bowie knife was sticking out of his back, a pain all too familiar to him. Blood seeped out Akiko's side and neck, running through the spaces of the tile floor. Quickly grabbing gauze, he began patching up her wound, shakily saying "Youre going to be alright. Stay calm."
Calmly, she smiled. The look in her eyes was a sign of euphoria, a symptom of massive blood loss.
Her eyes widened. The smile was quickly wiped from her face. At the same time, a large black rod burst from her chest, with a torrent of blood. Her body rose from the ground as the owner of it emerged from a portal in the floor. It was a male humanoid figure dressed in a dark green two piece suit, and top hat. Akiko was limply impaled on his cane. Throwing her off, he walked over to Damian.
"It hurts you, doesn’t it?" The intruder hissed. Looking over at the body, he smirked. "Actually, it probably hurt her more. I told you to stay out of my affairs, Mr. Warrington, you revealed my business, and now I’ve reached my wits-end."
"You ruin human lives!" Damian retorted, with eyes ready to tear up. From off a plaque on the wall, He ripped a particularly large sword with the word BANESTRYKE etched in the hilt. One side of the blade had three leather buckle straps. With tears flowing from his eyes, he screamed "GEOFF! SHOW ME WHAT KIND OF A MONSTER YOU REALLY ARE!"
He charged at Geoff with the extremely large sword. Damian slashed it with great force considering his bodily proportions. Geoff stood there, with a large dagger like the one in Damian’s back, ready to block a potential decapitation. With an abnormal ripping noise, like tearing meat with bare hands, He sliced Geoffs stomach deeply.
Not so much as a squeal came from Geoff, who still was smirking evily. He put his hand on the wound, pushing in a piece of flesh hanging out of his belly.
Suddeny, his image flashed and changed. His figure was now a red skinned, large, limbless, bulbous creature. Saliva reflected in his gaping blue mouth. A hypnotizing glare came from its singular green irised eye. A large, wide-open cut is across from where his cheek would be.
He is a Cacodemon: an Interdimensional creature capable of traveling on two sides of the world in an instant.
Damian dropped to the ground, terribly exausted. The creature bellowed a low frequency howl of pain, and warped away in retreat.
After desperately crawling toward Akiko’s lifeless mound, Damian sunk his fangs in her cold neck with tears in his eyes. Feeling her flesh, he'd found that it was too late
“Why…?” The sobbing faded off into the distance.
"Remember when you were a kid and you thought your dad was Superman, then grow up and realize he's just a drunk who wears a cape?"
