From Tardis Wiki, the free Doctor Who reference
The Testimony Foundation was an organization created on New Earth in the year 5,000,000,012 by professor Helen Clay of theUniversity of New Earth. Its purpose was to allow the dead of the past to give their testimony of their lives in order for future generations to learn from the past. In exchange, the deceased would be granted a new form of life as glass avatars in order to interact with humans. (TV: Twice Upon a Time)
