it just kept mushrooming and never quite went where I wanted it to so decided to do the hack and slash technique to it and try again but then realized the grave didn't have to be the Doctor's and the 'big bad thing' didn't have to be destroying the Tardis, etc... I kind of liked leaving it open and seeing what other people came up with (and I was a little amazed by the whole world created by fannishwaldo a few comments above yours)
