Chapter 1: The Birthday Girl.

I claim no rights to the Sherlock universe, BBC or otherwise. Any dialogue from the show is not my own.

Every now and then, though it cannot be measured in Earth time, a Being will fade through dimensions and manifest itself in a human body that is close to death, yet not deserving of dying. The process itself is unknown to the Below dimension, but the sole purpose of the events is to do good.

That is not to be said that they cannot do wrong; no, that is entirely possible (depending on the situation), but the outcome of their actions must always do at least one group of people some form of good. Murdering to save lives is always an option for them, even if some people would argue the opposite.

Our story starts sometime in January, though the year is uncertain. A young girl by the name of Kayla Robinson was running down the streets of London, pulling her mother by the hand, who was following her contritely. Kayla was very exited, and for good reason, as she had turned ten that very day, and her mother was taking her shopping, where she could tell all of her mother's friends that she was 'almost eleven'.

However, in the instance between New Oxford street and Oxford street, many things happened at once: Firstly, the mother's phone notified her of a text, and she stopped rather suddenly; secondly, dear Kayla toppled off the edge of the sidewalk, gaining her balance on the road; and thirdly, a car came whizzing around the corner. Kayla's mother rushed out on the road to fling her child out of the way, and she succeeded- but Kayla hit her head in the gutter, and fell unconscious, her life-blood pouring into the drain from a horrible gash on her scalp. Kayla's mother died on impact.

These are the events that lead to darling Kayla's body becoming the vessel of a fallen angel, whose only purpose was to help a small group of people devoted to helping others. Now, you need to remember what is written next- it is very important. This story is just an idea, something that has come out of someone's head. But, in the words of Albus Dumbledore:

"Why of course it is happening inside your head... … but why on earth should that mean that it is not real?"
