Name: Urubec

Sex: Male 
Age: 56 (very young for an elf) equivalent to twenties 
Height: 5 foot 10

Class: Assassin Thief

Appearance: Urubec is a typical dark elf, he sports long white hair, completely black eyes and slate gray complexion. Being a Spirit Walker he can shapeshift into his spirit animal at will. For Urubec this a black python. Otherwise he looks like a typical elf in his normal form. 

Background: Trained and raised in black markets and the legendary Thieves Guild, Urubec is a master of deception. His father was a well known trader as was his mother. Once they found his aptitude for sneaking they sent him off to be trained in the art of stealth. Through many years he became a deadly assassin and accomplished thief. He is considered one of the best of his time. 

Personality: Noble as all elves, Urubec is keen on taking higher moral standing and is well collected. His thief trade has made him much more adept at showing emotion than the rest of his elven brethren. He is loyal to those he deems good and is sharp in wit. 

Equipment/weapons/clothing: sporting the typical tan leather armor and black cowl of an assassin for the Dark Elves, Urubec carries with him twin daggers both crossing behind his back, he carries throwing knives at his left side in a leather sheath, and he carries various other tools for assassination and thievery in hidden niches across his suit and belt lined with several compartments. He takes gloves of leather, and boots meant for climbing. Standard fare for the stealthy. 

Special: able to shapeshift at will into a python, his size and strength in this form depending on how much energy he has at the time of transformation.
