This was a "PC villian" I have always had in my head and used in various campaigns as a Drow+vampre+ninja (yes i said ninja)... But I have never bothered to make him for 4th edition as of yet.
Barra'Quortek Buki'Jesshc has lost his true name to time, this is a good thing as true names hold power. Barras name was lost at the fall of his city, his city in the sence he is the only living survivor and therefor the only one right to claim its herritage, but who would want to claim a ruin as theirs?
Mind me I am ahead of myself.
Barra was unimpressive, a male in a Llolth-bound house he was looked past by almost all, he had little station above a servant and seemed quite comfortable in the shadows, often unseen even when in a room as his name was bellowed for attendance. For years he was the 'good' son, saying little and doing nothing to disturb his house, letting all honnor and praise fall to his siblings while he seemed to ride the coat-tails of his family name.
It is an odd thing what people will say or do when they think no-one is looking, rumor starting lies here, passionate trysts there, occasional "natural deaths" in the hallway alcoves and suddenly "missing" treasures. All watched by unimportant eyes. As time passed his siblings dwindled, from five sisters and two other brothers at his childhood, to only three sisters and one brother when he was ready to begin his training, all done in by one anothers hand while he simply watched and was ignored.
When it came to the time of training, he did well enough, his magical talents were nominal with particular flair for illusions and in the school of melee he was passable with his short blades, but the one thig of note from both schools reports was his stealth and subtlety. From the minimalist gestures and words needed for his spells to outright misleeding of his gestures to push out an entirely different casting from the mages school, to the stealthy defeat of his fellow students, many often left robbed, bound and gagged for others to inflict their wickedness unpon a helpless drow with one time of note that a victim was left as bait for an even bigger prey.
These ever so cunning defeats warrented the attention of Tui'jor, one of the few non-drow in the city and the only non-drow of anything resembeling noble status. Tui'jor was a Deepdwarf trapmaster and security consultant. As part of his consulting, one of the other houses brought Barra's skill into question as a credible threat to other houses and Tui'jor arranged for a meeting with this sub-rosa child involving a sleep spell and a large bag.
Barra awoke to find himself floating over an open pit. After the inital screaming and scrambeling he noticed his piwafwi had a note pined with a stilleto explaining he was in an invisable maze and if he escaped he would be rewarded, failure was death. The test was far shorter than most had expected as the first trap was a simple pitfall to the abyss below. Taking slow measure of the pits edges, length, hinged side, ect. He managed to climb down the hingedside of the open floor and used his natural levitation with a strong braced kick to coast out and away from the middle of the abyss to the edge of a wall and started to climb up, bypassing the maze entirely.
Declaring himself escaped under his own conditions he was greeted by the deepdwarf at the lip of the pit with an open hand to pull him up, on all instinct Barra put the stilleto hilt deep right into the pale dwarfs chest. As shocked a face the dead dwarf had, it was Barras turn to be suprised as the dwarf gingerly puled the knife out of his chest and slammed it into the side of Barra faster than he ever thought a dwarf to move, then the drow poison got to work and he was soon asleep once more...
The next time Barra awoke, he was being tended to by Tui'jor who seemed to show no malice to this victim and calmly explained that Barra was going to become a warrior of the shadow and the mind. Going to, no questions about it but a decleration, here his training began. While normaly this would be the montage of doing handstands over burning coals it was actualy much reading, blueprints, anatomy, herbalism, alchemy, geneology, Llolth scriptures... he read for years.
As time passed the books became less and the hard work began as he was forced to apply his readings to build his own weapons, armor and tools. Knowing the deepest workings of his spring-loaded balistic knife to the smokesticks and tindertwig bundles to his first hand carved blade and persoanly crafted chainmail armor with links as fine as any gnomish jewlers necklace.
(Stopping here for now as it is 5 AM, more next time.)
Interesting.
I am now waiting for next time. 
EDIT: So far he sounds like he could make for a cool PC. I'm guessing, however, that the dwarf will not turn out to be a follower of Eilistraee....
Having been gone so long it was no suprise his family declared him dead and with more important things to do it was easy to overlook another male servant. For the moment Barra was a spy within his own house, simply taking notes and little more, when raids came he was always somewhere else to avoid the casualties and recognition. When hunting parties patrolled the caverns was when he worked his physical prowess, doing all he was trained to place a slowed or maimed foe before another to finish off, all the while watching and learnig how the others fought as well as who kept their weapons or other trinkets on themselves untill they died in the tunnels and slightly less treasure was divided amongst the survivors.
For half a decade he practiced under his own roof and under the noses of his family untill Tui'jor came to upgrade the security to his families home, under this guise Barra gave five years of reconasance and lifted items to his teacher and given his first grisly assignment: To assassinate one of his twin sisters. Immediately fearfull that such a task was beyond him, Barra asked for an alternate assignment and recived a broken rib from the deepdwarf for doubting himself. The only tools he was given was a vial of poison even he couldnt identify and a strange wooden dagger, strange in the fact the wood was not of any mushroom he had ever seen.
Steeling himself he used what he knew of his sisters to pick his target, the cleric was obviously too dangerous to go missing in a house of Llolth, but the mage would be missed far less, especialy if set to be in doubt of Llolths favor. This came about far easier than expected as it only took one remembered lesson from the mage school. He came upon the sisters chamber while both within and begged for forgiveness as he proposed a question:
"Magi Se'sahna has many powerfull spells in her arsenal, all which could destroy him in an instant, but does not the spell of spider climb require eating a spider to imbune oneself? Eating the spider takes its life and even a female drow, the adopted children of Llolth, is not above slaying the true child of Llolth without being put to death themself by an agent of Llolths will such as Vicar Le'aiana?"
Se'sahna's face twisted into rage at his impudence and as she began to speak the word of pain she was struck forever silent by the one person who had known her every moment of her now ended life. Expecting his fate to be the same as his dead sisters, he was shocked by the soft sensation upon his face. Looking up he saw his priestly sisters hand upon his cheek, the other hand held her black bladed sacraficial dagger lodged to the hilt in her twins neck. "You have spoken truth, therefor you live, if I see you in these halls again I will kill you." The sister left just as easily as she slew her sister, presumably to pray to the goddess she just defended.
Not wanting to end up with more than broken ribs, he slid his sister onto her bed and slipped the vials contents down his dead sisters throat to plant the poison before he looted the room for arcane treasures. He was working upon the contents of her bookshelf when he heard the words of arcane power being chanted. With eyes upon the door this whole time he was stunned that anyone could have gotten past him when it came to the realization that the voice was his sisters, his dead sisters.
Her voice was strained due to the open hole in her throat, but also the inch long fangs protruding from her mouth that her lips seemed to have a hard time wraping around to pronounce her spells correctly. This was all the opening Barra needed to rush in fast and plunge the wooden dagger into her heart, a natural cause of death in the drow world, with the strange side effect that her black skin began to pour off like ash from a campfire, leaving not even a bone for her jewlry to rest upon. Thinking swiftly he scooped up the ash and left with his horrifingly well earned gains and many grim questions to be answered.

Go on please, the story was wonderful!
