Time's Child (A Doctor Who Fanfiction)

There is an ancient time lord myth that their is someone known as the child of time. More powerful then the time lords and even time itself. They have the power to do anything to time no consequences. They are more powerful then anyone as their will only ever be one time child. If they are to eventually die their soul will be passed to the next child capable of being the time child.

But If course it's just a myth.

It had been a while since the Ponds had left and the eleventh doctor was now traveling with a girl named Clara Oswald.

They were heading on a trip when the TARDIS landed them in a home for young girls with no parents where they meet Kaya or Kay Pond the twin of Melody Pond and Amy and Rory's lost daughter they never knew about.

Well at the house and sometime round Kaya they get weird readings. Powerful readings that make things go off the charts but sometimes they aren't their.

Could there really be a child of time? And if so is it Kata or someone else?
