Un-born

"Just as the human mind cannot comprehend time, so it cannot comprehend the damage that will ensue if we presume to tamper with its laws."

- Professor Saul Croaker.

"Un-born" is the term used to refer to someone who vanishes into nothingness, as a result of a disturbance in time itself, in which someone travels back in time and, due to their influence, history is changed to some degree, culminating in the disappearance of people in the present, as the events leading to their births are prevented or altered in some way.

When Eloise Mintumble travelled back in time to the year 1402, in 1899, there was a major breach of the laws of time, with catastrophic results. For one, Madam Mintumble was stuck in the 15th century for five days, and when she was finally retrieved to the present, her body had aged five centuries and she later succumbed in St Mungo's Hospital for Magical Maladies and Injuries. Also, there were at least twenty-five people (all of them descendants of people Mintumble had met in the past) who vanished into thin air, effectively becoming un-born. Finally, the Tuesday that followed the ordeal lasted two and a half full days, while the following Thursday lasted only four hours.
