Reinhard Metzger

Race:  Human
Class:  Witch Hunter
Army:  Empire

Reinhard Metzger is a tall, broad-shouldered man in his forties.  He has long white hair that he sometimes ties back but is usually messily falling back over his shoulders.  He wields a bastard sword named Pennance and wears a dark cloak over chain mail.  His warhorse's name is Horse and his warhound's name is Dog.  The fact that he didn't name his sword Sword is often debated by those who know him.
Metzger didn't become a Witch Hunter because of any overwhelming hatred of Chaos or sorcery.  He simply thought it was a cool job and a quick way to power.  A few years of hacking through ancient tunnels and dusty mansions searching for evil books plaguing the land or withered old necromancers hiding in crypts changed his mind.
His defining experience started when he was chasing down the necromancer Filip Vyle.  Vyle had been an apprentice to the ancient necromancer Tulmoniam, whose army had just been defeated on the fields of battle by agents of the local Elector Count.  Metzger had fought in the battle at the head of a regiment of flagellants.  His job had been to make sure that nothing escaped the field of battle.  He failed.
The elector count decreed that it was Metzger's job to find the necromancer and bring him to Sigmar's justice.  The Witch Hunter was dispatched with fifteen Imperial soldiers and a few of his most loyal flagellants.  The track took months as the necromancer fled through evil marshes and dark forests.  The little towns he stayed in for the night were always tainted by his presence, and Metzger always had to stop to cleanse them.
He had to stop at one town to fight off an attack of Beastmen on the town's stockade.  When reinforcements arrived Reinhard hurried off to make up for lost time, but not before eight of his soldiers had been killed by Beastmen.
Finally the two met in a ghost town on the edges of the Empire.  Reinhard strode forward confidantly, declaring that the necromancer's reign of terror was over.  Vyle only laughed.  When the Witch Hunter advanced to dispatch the evil man, the necromancer raised his hands and started shrieking a spell.  The ground around them erupted with undead, and the Witch Hunter's band found themselves fighting for their lives.  Metzger, with the help of Dog, fought his way through and managed to somehow overcome the necromancer.  Vyle was still smiling when Pennance drove through his black heart.
With the death of the necromancer the Imperial band prepared to leave.  Metzger made sure to dispatch the necromancer properly and said the prayers to clean the area of the evil that had been around it.  Just as they were about to leave, a soldier ran over to Metzger.  He told him that during the fight he had fled for his life and taken shelter in the largest building of the town, apparently a disused church.  Inside he had found several children, no doubt stolen by the necromancer for disciples of his own.
When Metzger investigated he found most of the children dead, apparently from the backlash of evil from their dying master.  Only one, a dirty and terrified little girl, was still alive.  Metzger knew that she was tainted and should be destroyed, but he stopped his sword long enough to talk to the girl.
She tearfully said that she had been forced from her village by Vyle and wanted only to go back.  She pleaded tearfully with him and the Witch Hunter's heart was moved.  He agreed to let her live, but only if she went and studied at the Imperial Academy to learn to use her magical potential for good.
He dropped her off a few weeks later.  She was cleaned up and her eyes shone with the chance to learn magic.
Ten years later Metzger was in Sylvania hunting an ancient Necrarch.  From frightened villagers he heard tales of a new queen that had awakened the vampire and unleashed his hatred upon them.  After several skirmishes with the vampire's minions he cornered the beast in an abandoned chapel deep in the forest.  Metzger had been forced to leave Dog behind, for he was now very old and useful only for tracking.  Horse had died years before, and a new Horse had taken its place.  No horse, however brave, was willing to enter that evil part of the forest, however.  So Metzger faced the vampire alone.  After a terrifying fight he overpowered the vampire and destroyed it.  The fight had cost him greatly, and the powers of the ancient thing had turned his hair white.  As he slumped out of the house, a figure rose up to stop him.  It was a young woman, beatiful and dark, barring his way almost nonchalantly.
She raised a hand to destroy the Witch Hunter, but hesitated.  She looked at him, dripping there bloodily and gasping for breath, and a laugh escaped from her mouth.  "Recognize me, Witch Hunter?" she asked.
In an instant Metzger realized that this was the same little girl he had spared a decade ago.  He was speechless, and stared in mute horror at his own death.
Black fire wreathed the sorceress as she prepared to destroy the beaten man before her.  She laughed, the sound echoing off of the ancient trees around.  As Metzger closed his eyes and breathed a prayer to Sigmar to accept his death, he heard a low, rumbling growl.  He opened his eyes to see Dog, his faithful old warhound, emerge from the trees.  The sorceress half-turned before the dog was upon her, massive jaws locked around her once-flawless throat.
Metzger watched, amazed, as his old companion mauled the body of its victim.  Its job complete, it limped painfully up to its master.  It was not a young animal any more, and the Witch Hunter was amazed that it had been able to catch up to him at all.  The fierce loyalty in the hound's eyes made Metzger realise that here was the one being that he could ever count on.
The walk back was a long one that day, as both of them were getting older and had been through too many fights.  It was a thoughtful one, though, and was good for them both.

Origins:  I've wanted to make a Witch Hunter character ever since reading the Mordheim rulebook.  This guy came from signing up on the Warhammer World forum.  The name comes from looking for "German names" on the internet.  Metzger, of course, means Butcher, and Reinhard reminded me of sticking a sword into somebody.
