Un-born

Un-born is the term used when a confusion in time happens where a person travel back in time and changes history causing certain present-time people to disappear as the events bringing those people are prevented.

This accidentally happened to Eloise Mintumble, a witch from the 1800s who travelled back to the year of 1402 via Time-Turner and accidentally got stuck during that year for five days. She did something that would change the history totally, and when some specialists finally got her back her body had aged five centuries, twenty-five descendants of the people she had met vanished into thin air and the following Tuesday lasted two and a half full days while the Thursday lasted only four hours.
