Edward Grainger

History
During childbirth, Edward's mother and family were under attack by a Demon. The Demon wanted to possess Edward's body and use it as a vessel so it could live in the real world. The Doctor, however, managed to banish the Demon before it caused any harm to Edward. (ST: Prologue)

When Edward was 8, The Doctor came to visit his house to investigate voices that Edward was hearing in his gramophone. The Doctor found that an alien had been trapped in the player while it was being made and was trying to escape by screaming for help. The Doctor freed the alien and allowed it to go home, while the Doctor was laving he told Edward that he would lead a very eventful life. (ST: Echoes)

Later in Edward's life the Doctor came to visit Edward and took him on one last adventure in the TARDIS to the village where he was born in 1906. Edward slept in the TARDIS during flight and was called in his dreams to the Eye of Harmony. A voice told him to open the Eye and in doing so Edward released the Master. After a long search with the Doctor to find the Master, Edward sat down in the TARDIS to rest and died in his sleep. (ST: Forgotten)
