This looks like a sound RP. 

Just to say, I wasn't sure whether a 'free-running' skill could be counted as a speciality, as most thief guild rp's tend to have that as a default skill for characters, but I've put it as a speciality for my character for the time being. Please let me know if free-running is considered a default ability in this rp and I will gladly change it to something else. Also, in my character's bio I alluded to some vague aspects of the Guild's organisation, please let me know if these don't fit in with your own established background and I'll change it accordingly.

[centre]Slender and lean in build and height, Shae cuts a perfect figure for flighting across the rooftops and slipping into the shadows unnoticed. Though the majority of her is slim, almost lanky, there is a noticeable definition in her upper arms, as well as a stretching bulk of muscle in her legs that allow her to sprint across the tiled upper reaches of any town easily.[/centre]

[centre]Her skin is a pale ochre colour, whilst her hair is a dark-russet that hangs on either side of her face in sharp strands, before curving upwards shorter and shorter until the back of her head, where her hair is cut in a close shave. She is known to, at random intervals, get fed up with the weight of her hair and shave it all off.[/centre]

[centre]Shae uses every aspect of her body to her advantage and, whilst she is rarely seen without a hood-mask covering the lower half of her face, she presents her sharp, green eyes freely, as their piercing keenness has been known to throw off some opponents, sometimes long enough for Shae to dismantle their attack and escape. When bare-faced, Shae is seen to possess almost fox-like features with a tight face and a slightly upturned nose, and her strong jaw allows a subtle androgyny. Light dustings of freckles are scattered across her pale body, most prominently on both of her shoulders, and she possesses two tattoos, a small string of words written in a dead language around her right ankle, and two impaled arrows on the inner flesh of her left forearm.[/centre]

[centre]Personality:[/centre]
[centre]Quiet but very curious, Shae is friendly enough and can cooperate well with most others in the guild, should they be friendly themselves. However, if her teammate is particulary agressive or standoffish, Shae will lack the will to truly work with them, and this can lead to her ignoring their plans of attack, or even abandoning them all together if the job falls apart. This behaviour comes from a desire of self-preservation, where Shae seeks to simply survive and benefit herself, not out of any large amount of greed but instead from teachings instilled in her from a young age.[/centre]

[centre]Preferred Weapon(s):[/centre]
[centre]Bow and arrow, throwing knives, Shae also employs a small arsenal of smoke bombs as distraction and escape techniques[/centre]

[centre]Abilities and Specialties:[/centre]
[centre]Sharpshooting, Free-running[/centre]

[centre]Bio:[/centre]
Born into a dying Mother's arms on a dark and cold street on the cusp of winter, Shae was traded into a workhouse where she grew into a coy and guarded child, known and scolded for dirty hands and feet from attempting to dig an 'escape tunnel' from the workhouse and from climbing up the pipes and bricks to try jumping over the high walls that surrounded the workhouse. On one of the workhouses many 'open days' where lower Houses and Guilds would visit to appraise the array of children on display and assess their skills and worth for service, Shae sought to use the commotion of the crowd as a distraction so she could safely scale the walls and escape without notice. When she was discovered, the ease with which Shae delivered a bludgeoning projectile blow to a caretaker with a piece of roof tile from a fair distance, caught the attention of the Head of House Mag, a small but warm family weighed down with bad luck and unfortunate circumstances. 

The Head of House Mag, a merchant with a fondness for the bow and arrow, brought Shae and set her to work in his houses' kitchen and, in an odd show of interest in a servant, began to teach Shae the basics of archery, having her accompany him and his two young sons on hunting trips, and gifting her with her first bow, a shabby piece of work that Shae dutifully kept clean none the less. Three years passed, and at the age of ten Shae had surpassed her master in the bow and made a point of expressing this, and her desire for further education, by climbing to the roof of the small manor House Mag resided in and shooting sparrows out of the sky every morning. However, fond as he was of Shae, the Head of House Mag could not afford to provide Shae with such education, as his business and house fell into deeper and deeper debt, to the point where bandits, hired by various debt collectors, were camped outside the manor. The stress and fear soon overwhelmed the Head of the house, and he was found one morning, body slumped across the damp bank of the pond in the manor gardens, his head beneath the murky surface of the water. 

Ashamed by her Husbands suicide and fearful for her and her childrens safety, the Lady of House Mag quickly handed over the manor and most of their possessions to the bandits and debt collectors and, when it still hadn't covered the amount of debt, turned over the bulk of the house staff, including Shae, in addition. And so Shae found herself in the possession of bandits who made use of Shae's shooting skills, which they had spied when camped outside the manor, and had her catch birds, allowing her to keep her bow as she, along with other staff, were herded across the country to the Capital, to be sold in the market. 

Eager to fetch a higher price, the bandits had Shae perform archery for the crowds in the market, her skill impressing one hidden figure in particular, a scout for the Thieves Guild. Returning in the early afternoon with several superiours, the scount pointed out the skill Shae had with the bow and persuaded her superiours to purchase the girl. After a short, concise meeting with the bandits, where coins were exchanged and maybe some daggers held to throats, Shae was brought into the Thieves Guild and given a newer, firmer bow that serves her well to this day.

It is in the Guild where she learned to master her skill, delivered into the charge of Olos the Bowmaster, from whom she learned a great deal in the art of projectile weaponry, and was moulded into a quiet, cunning but overall more approachable being under Olos' firm and wise tutelage. Within the Guild, Shae became known for her swift delivery and quick hands, and was soon branded with the insignia of her chosen weapon class, two arrows impaled into her flesh, one arrow for her past and one arrow for her future, as Shae looks to push herself higher and higher until she can soar alongside her arrows in the air.

Other info: I should also like to, if I can find the capability, to write Olos and his daughter, Lim, into the rp, however they'll only be minor characters and should only appear in relation to Shae, so they won't require a CS. Also feel free to decide for yourself how well known Olos is within the Guild, or if he can even be considered a Bowmaster.
