Gallifrey was the home world of the Time Lords. It was believed to have been destroyed in the Last Great Time War but was, in fact, frozen in a pocket universe by the first thirteen incarnations of the Doctor, and later discovered at the End of the Universe. The literal translation of Gallifrey was "They that walk in the shadows".

I am planning to add an interior and possibly the village around Gallifrey. Perhaps even the time vaults, un-tempored schism, ect
