2003

Likely the most significant event of 2003 was the April death of Liz Shaw. By the time of her viral-related death, she had become Chief of Operations at Tranquility Base on the Moon. (NA: Eternity Weeps)

2003 also saw Ruby Duvall became a reporter for the Sunday Seeker (NA: Iceberg).

On the 23rd of August, the Doctor, Ace and Bernice Summerfield arrive at the Pinehill Crest Hotel in time for: A demonstration of spiritual channelling, a show of a temporal accelerator and a cross stitch convention and an attempt by the Scourge to manifest in our reality.
