Count me in
Name: Vic (I'm always too lazy to think of cool names for my characters in DnD or other games, so I use my real name

)
Race: Human
Occupation: Goes from town to town and does minor magic things for payment, in the meantime he experiments with his magical abilities
Equipment: Quarterstaff (Hand Weapon), Ritual Knife (as 2nd hand weapon), light leather armour and a really strange looking traveler's cloak (actually a Sea Dragon Cloak).
Background: As a child (around the age of 14), his village was attacked by a raiding group of Dark Elves led by a Sorceress. His parents and most of the village were murdered in a despaired try to hold the intruders. The others, including him, were taken as slaves.
Vic was really scared when they tried to put him in chains, and from somewhere deep within some ancient runes "popped up"

P) in his mind. As he spoke them the corsairs that were trying to shackle him were thrown away. Confused from what he did he froze there for a few seconds before he tried to run away, but by that time the sorceress was already coming for him and was whispering some shadow words of power. Before he knew, he was already lying unconscious on the ground.
~~Kinda lazy to continue like that, so I'll shorten in down:
The sorceress "erased" his mind and decided to 'train' him as her apprentice, because Vic looked a lot like her lost little brother, that she cared for when she was a child before a lot of decades, so in a moment of humility she decided to take care for him.
After a few years of training he was showing great potential, but something was holding him from being able to use magic. The sorceress was getting impatient with his slow progress and one day after his failure to do anything she realized that she doesn't really have a reason to keep doing this and cursed her weakness a few years ago.
Without explaining anything she took Vic to the sacrificial chamber (or whatever dark elves use) and without any hesitation bonds him to the altar - his blood would wash up her moment of weakness.
In that very moment the human felt the same way as he did back in the village - he saw the same ancient runes, but this time... this time it was different. In the few years of training, although he didn't have much of a success, he was a diligent student and this time those runes didn't scare him. He knew exactly what to do, and the dark elves though him well - he didn't feel anything as he concentrated his powerful magic at his former teacher.
The sorceress wasn't prepared for this (rolled double 1 to dispel) and felt how with every second passing, she was getting old with decades. In a matter of seconds everything was over, and Vic was standing in front a pile of dust. He grabbed her ritual knife, quarterstaff and found his way out of the dark elven village (or whatever dark elves live in).
What he did was incredible - probably with a lot of luck, he managed to do the same thing Nagash came to after years of studying the DE magic - he found his own kind of necromancery.
With the death of the sorceress, his memory came back and he decided that one day he'll get his revenge on the elves for what they did to his entire village.
to be continued...
this story is kinda stupid, but is what I have as a general idea for my character, and that's my explanation why he has access to some necromantic spells.
