Vyxin is a night elf / blood elf hybrid. For the first portion of her life, she lived with her Father in Darnassus. During this time she was very content and carefree. Though, when she was about 10, her father was called to battle and he never made it back.
Therefor she went to Silvermoon to stay with her mother.
Once living with her mother things changed dramatically. Her mother was very expectant and judgmental about Vyxin. Nothing was ever good enough and it seemed Vyxin could do no good, in her eyes. Because of this, Vyxin pushed herself to the breaking point. She was constantly training, studying, doing work and trying her best to earn her mother's approval. Everything was strict and structured, and had to be exactly perfect. Through this upbringing, Vyxin became quite the scholar, and became one of the very best Warlocks in all of Azeroth. Her work ethic was unmatched and her focus unwavering. Vyxin's main area of expertise quickly became demons. She learned to speak fluent demonic, could tame even the most unruly demon, given the correct circumstances, and seemed to be respected even among the most ruthless of them. This made her the go-to Warlock for anyone seeking information or instruction on demons and realms. And, on several occasions, Vyxin was called into fights against the most formidable of demons or other Warlocks, due to her expertise. Her imp came from such an occurrence. After defeating a malicious warlock terrorizing Azeroth, the imp clung to her, pledging his life and his loyalty in exchange for her saving his life. He is very protective of her, and fiercely loyal. Defeating this Warlock also had her world renowned and held in the highest regards. However, it still wasn't enough to meet her mother's outrageous standards.
Vyxin set off on her own, at this point, no longer abiding by any form of structure or rule. She traveled as she pleased, did as she liked, and acted how she wanted from that point forward.
these days she's a rather happy, giddy, loner, traveling around Azeroth on whims and doing what she wants. She still offers her advice or information when asked for it, as long as she's adequately paid or accommodated. It's very hard to get her serious, due to her use of hallucinogens and her general lack of caring about serious matters. However, she can be a rather great force to be reckoned with, when she -does- get serious
This was so spawned from an idea Cerzz and I were tossing around XD don't know if she fits the bill, but this is what I came up with XD
