There are many tomes reputed to tell the tale of Black Marentail, first of necromancers. However, none of those fools ever had to live with him.
Marentail first took up the study of magic among the city-states of Misake. A young, bored noble, it was expected of him to learn the arts of war. Though in this he trained, he had a mind for books - and a talent for magic. So long as he performed as his parents demanded of him, he was allowed to pursue his hobby of magic, so long as it did not interfere with his "true" studies.
However, Marentail was always cruel and his parent's indulgence and air of superiority made matters worse. He'd killed his hunting hound by strangling it when he was only seven after it failed him in a fox hunt.
Animals were not the only things he was cruel to; he'd conspire to dismiss his father's servants just to see their agonized faces, and he'd advise his father to have those he dueled with among his father's guard sent to the front line, just to smile as their bloodied corpses were returned after a battle.
When only seventeen, his temper took it's first human life; he ran through one of his father's generals for reprimanding him. He'd often lashed out against those around him, and after that incident, all too often the result was the death of those nearest to him. His parents looked the other way on too many occasions, but even they could not forgive him when not only refused to marry the wife his parents had chosen for him, but drowned her out of scorn. With his murderous temper, he could call no being his friend and it only made him more callous towards others.
When his parents threatened to take him from his magical studies and enroll him in a military academy, he poisoned them to blackmail them into relenting; this I know because he himself told me this on several occasions. He did so quietly, and it took years for the poison to finally kill them. Those who knew him best had no doubt that Marentail was somehow responsible for the death. Regardless, by the time Marentail was nineteen, he'd inherited his parents wealth and lands, and the soldiers that went with it.
He'd faced a ghost when he was only twelve, and though he'd bested it, that experience had turned his hair white. His encounter with the ghost had sparked some mad desire to learn more about the undead. He would use those who fell to his wrath as fodder for his magical experiments. Quickly, he learned how to animate the fallen corpses into undying soldiers who were tougher and more pliant to following his commands. By the time he was twenty-three, he was no longer surrounded by the living; all that he commanded were undead. And he desired to expand his empire, for he needed more fodder with which to experiment.
As much a conqueror as a sorcerer, Black Marentail rode with his undead horde into the surrounding lands, establishing a kingdom of his own. When once a few brave fools dared to raid his undead keep to steal one of his magic tomes for a wizard on our town council, I came under his fell gaze. He traced those who stole from him back to our town, arriving moments only after our glorious councilor teleported away to save his own hide.
Black Marentail spared no one in our town in his wrath - no one but me, that is. That day, something in my sorcerous blood sparked. It was something as simple as a Charm Person, unconsciously unleashed by my terrified mind, that saved me. Marentail told me he was impressed that I did not cry or recoil at his or the undead's approach, but I know the secret truth that saved me that day.
For seven years, I have labored as his apprentice. He has tortured and defiled me, but I have not flinched within his presence. Still under the sway of that ancient spell, he calls me friend, and I will not allow him the pleasure of seeing my pain, fear or hatred of him. For most important of all, I have survived. Perhaps, because of me, others have as well, for now there are eight apprentices under Marentail, where once there were none. Marentail has even adopted a daughter, which he has taken to teaching her magic.
In the upper reaches of his great tower, he toils between cullings of the countryside on mastering the depths of magic. When he can no longer control his hunger for companionship, on those horrid nights he tells me of the secrets he is slowly unlocking. He has mastered the spells of the eighth circle, standing on the verge of grasping those of the ninth. He rants into the night of his quest for spells of the tenth, eleventh and twelfth circle - daring to reach into the magic of the very gods and snatch it from them for his own use.
However, I am under no illusion how tenuous my position is. Those apprentices foolish enough to show too much promise too quickly have fed his unsavory appetites, their knowledge devoured and then their bodies destroyed, or simply destroyed when Marentail could not fathom the secrets they held. Every night I dream of the corpses of my parents and kin who toil the fields outside the tower, and I dream of some way escaping. I dream of my revenge against him.
For I know what terrifies my master - he fears his own death. I have heard him awaken in the nights, howling that his own servants are rending the flesh from his very bones. I know what horrors he has seen, for I have often been forced to assist him in his labors; these labors of such horror that he fears falling prey to them at the hands of the undead he has created or the apprentices that he teaches.
I swear that one day, I shall be his doom. I will be the hammer that crushes him against the anvil - the tool that shall see him strapped to his own Bloodforge and drained of the life and magic like he has done to so many others.
